Adafruit DC & Stepper Motor HAT - Mini Kit (Adafr DC & Step Mini Kit)

Let your robotic dreams come true with the new DC+Stepper Motor HAT from Adafruit. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control.

Raspberry Pi and motors are not included.

Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins.

In fact, you can even stack multiple Motor HATs, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include.

Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel and 3A peak current capabilitya big improvement over L293D drivers and there are built-in flyback diodes as well.

We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested here at Adafruit so all you have to do is solder on the included 2x20 plain header and the terminal blocks.

Lets check out these specs again:

  • 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
  • Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
  • Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
  • Big terminal block connectors to easily hook up wires (18-26AWG) and power
  • Polarity protected 2-pin terminal block and jumper to connect external 5-12VDC power
  • Works best with Raspberry Pi model A+, B+, Pi 2 B or Pi 3 B.
  • Install the easy-to-use Python library, check out the examples and you're ready to go!

Comes with an assembled & tested HAT, terminal blocks, and 2x20 plain header. Some soldering is required to assemble the headers on. Stacking header not included.

Raspberry Pi, motors, and battery pack are not included but we have lots of motors in the shop and all our DC motors, and stepper motors work great. Check out Adafruit's detailed tutorial for tons of info including schematics, wiring diagrams, python libraries and example walkthroughs.

Raspberry Pi Spy Camera (spy camera)

Is your house haunted? Or, rather, are you convinced that your house is haunted but have never been able to prove it since you've never had a camera that integrated with your raspberry pi but was still small enough that the ghosts wouldn't notice it?

Luckily, the Spy Camera for Raspberry Pi is smaller than a thumbnail with a high enough resolution to see people, or ghosts, or whatever it is you're looking for. It's about the size of a cell phone camera - the module being just 8.5mm x 11.3mm - and has a stick-on back so it's easy to mount in a doorbell or behind a teddy bear's eye (might as well be creative!)

The camera comes with a 289mm (11.4") long cable so you can extend and mount your Pi away from the camera. Like the Raspberry Pi Camera boards, it attaches to your Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data.

The camera is connected to the BCM2835 processor on the Pi via the CSI bus, a higher bandwidth link which carries pixel data from the camera back to the processor. This bus travels along the ribbon cable that attaches the camera board to the Pi.

The sensor itself has a native resolution of 5 megapixel, and has a fixed focus lens onboard. In terms of still images, the camera is capable of 2592 x 1944 pixel static images, and also supports 1080p30, 720p60 and 640x480p60/90 video.

Adafruit PiTFT 2.2" HAT Mini Kit - 320x240 2.2" TFT - No Touch (Ada no touch 2.2)

This product contains only the display. Raspberry Pi, case and cables are shown for illustration purposes only and not included.


The cute PiTFT got even more adorable with this little primary display for Raspberry Pi in HAT form! It features a 2.2" display with 320x240 16-bit color pixels. The HAT uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top of your Model A+ or B+ and fits into our case quite nicely.

It's designed to plug directly onto the Raspberry Pi 2 or Raspberry Pi 1 Model A+ or B+ . While not specifically designed for Pi Model A or B,you can use it with A/B if you solder in an extra-tall 2x13 header (not included) instead of the included 2x20 header.

This design uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25. All other GPIO are unused and are available on a 25-pin long breakout line. Since we had a tiny bit of space, there's 4 flat tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.

Comes as a fully assembled display PCB and an additional 2x20 GPIO header. Some light soldering is required to attach the 2x20 GPIO header to the HAT but it's fast and easy for anyone with a soldering iron and solder. You can also swap the plain female header we have with a 'stacky' type that lets you plug in a hat or GPIO cable on top or a slim ultra-low-profile header.

Technical Details

  • Board Dimensions: 65mm x 57mm x 6mm / 2.6" x 2.2" x 0.2"
  • Screen Dimensions: 55mm x 40mm / 2.2" x 1.6"

Tutorials

To make it super easy for use: Adafruit have created a custom kernel package based of off Notro's awesome framebuffer work, so you can install it over your existing Raspbian (or derivative) images in just a few commands. Their tutorial series shows you how to install the software, play small videos, or display images such as from your PiCam and more!

PiTFT Mini - 320 x 240 2.8" TFT Capacitive Touchscreen (ada 2.8 touch)

Raspberry Pi not included

Adafruit's best-selling PiTFT just got a fancy upgrade, now we have a version with a capacitive touchscreen! That's right, instead of a resistive touchscreen, which requires a fingernail or stylus, you can now use a fingerpad. The screen looks much nicer, with a black bezel and glass overlay.

Featuring a 2.8" display with 320x240 16-bit color pixels and a single-touch capacitive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top!

It's designed to fit nicely onto the Pi Model A or B rev 2 but also works perfectly fine with the Model B+ as long as you don't mind the PCB overhangs the USB ports by 5mm, see the photos above. Model B rev 1 have an older layout for the I2C pins and won't be able to use the touch screen

Uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. All other GPIO are unused and you can still share the I2C pins with sensors, LED drivers, etc. Since we had a tiny bit of space, there's 4 spots for optional slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button. See below for the link to get the optional tact switches, they're not included.

The screen is the same size as the resistive type so you can use this with the PiTFT PiBow or any other enclosure you may already have. We also use the same SDL device and signals so PyGame and X11 based programs can be swapped in with no changes in code.

This version comes as a mini-kit, with a 2x13 extra-tall female header (to connect the plate to the Pi) and a 2x13 male header that can be used to connect an IDC cable or cobbler from the side. The photos above also show the optional installed slim tactile buttons. The tactile buttons are not included. Some basic soldering is required to install the headers. You can also pick up an extra-long Pi stacking header if you want to install that instead of the 2x13 female header installed.

Technical Details

  • Display current draw is mostly based on the backlight, with full-on backlight the current draw is ~100mA.
  • Screen Dimensions: 50mm x 69mm x 4mm / 2" x 2.7" x 0.16"
  • PCB Dimensions: 56mm x 85mm x 2mm / 2.2" x 3.4" x 0.08"
  • Weight: 44g

Adafruit TB6612 1.2A DC/Stepper Motor Driver Breakout Board (1D2 Adaf TB6612 stepper driver)

Fire four solenoids, spin two DC motors or step one bi-polar or uni-polar stepper with 1.2A per channel (3A peak) using the TB6612.

 We really like these dual H-bridges, so if you want to control motors without a shield or HAT these are easy to include on any solderless breadboard or perma-proto.

We solder on TB6612 onto a breakout board for you here, with a polarity protection FET on the motor voltage input and a pullup on the "standby" enable pin. Each breakout chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. Just make sure they're good for 1.2 Amp or less of current, since that's the limit of this chip. They do handle a peak of 3A but that's just for a short amount of time. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver!

There's two digital inputs per H-bridge (one for each half of the bridge) as well as a PWM input per driver so you can control motor speed. Runs at 2.7V-5V logic. The motor voltage is separate from the logic voltage. Good for motor voltages from 4.5V up to 13.5V! This wont work well for 3V motors.

Comes as one assembled and tested breakout plus a small strip of header. You'll need to do some light soldering to attach the header onto the breakout PCB. Arduino, motors, and power supply not included. Check out the handy tutorial on assembly and wiring!

Adafruit Raspberry Pi B+,2,3 model B Case Smoke Base With Clear Top (Ada case smoke/clear)
This enclosure was designed by Mike Doell over at Adafruit - just like their elegant, beautiful, and functional Pi Case for Raspberry Pi Model B.  Made of ultra-durable, super-glossy polycarbonate, it is both good looking and tough enough to toss into your bookbag or toolbox. It has slim openings for all your cables, an easy-to-remove beveled slot for your Micro SD card, slots for both your Pi Camera and upcoming Display, and a space for your GPIO cable to extend out from the Pi.

The Pi snaps into the base and the lid fits snugly onto the top.  If you want to break out your Pi you can use your case without the lid and add hats to your Pi with ease.

This case works for the Raspberry Pi Model B+ only.  It does not work for the Raspberry Pi1 Model A or B.

Adafruit 12-Bit DAC w/I2C Interface (MCP4725) (Ada DAC converter)

Your microcontroller probably has an ADC (analog -> digital converter) but does it have a DAC (digital -> analog converter)??? Now it can! This breakout board features the easy-to-use MCP4725 12-bit DAC. Control it via I2C and send it the value you want it to output, and the VOUT pin will have it. Great for audio / analog projects, such as when you can't use PWM but need a sine wave or adjustable bias point.

The ADDR pin is broken out so you can connect two of these DACs on one I2C bus, just tie the ADDR pin of one high to keep it from conflicting. Also included is a 6-pin header, for use in a breadboard. Works with both 3.3V or 5V logic.

Some nice extras with this chip: for chips that have 3.4Mbps Fast Mode I2C (Arduino's don't) you can update the Vout at ~200 KHz. There's an EEPROM so if you write the output voltage, you can 'store it' so if the device is power cycled it will restore that voltage. The output voltage is rail-to-rail and proportional to the power pin so if you run it from 3.3V, the output range is 0-3.3V. If you run it from 5V the output range is 0-5V.

Adafruit have an easy-to-use Arduino library and tutorial with a triangle-wave and sine-wave output example that can be used with any 'duino or ported to any microcontroller with I2C host. Wiring it up is easy - connect VDD to your microcontroller power pin (3-5V), GND to ground, SDA to I2C Data (on the Arduino Uno, this is A4 on the Mega it is 20 and on the Leonardo digital 2), SCL to I2C Clock(on the Arduino Uno, this is A5 on the Mega it is 21 and on the Leonardo digital 3) and listen on VOUT.

Adafruit 4 Channel I2C 12-Bit Analogue to Digital Converter (ADC) (Ada ADC converter)

The Raspberry Pi does not feature an Analog-to-Digital Converter (ADC), so if you want to measure analogue singals, you'll need this 12-Bit ADC!

The Adafruit 4-Channel I2C 12-Bit ADC is a high-precision ADC and features the ADS1015 chip, which provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier,with up to x16, to help boost smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter. 

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet and interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5 in downloads below) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs. 
 
To get you started, we have example code for the Raspberry Pi - Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.
 
The Adafruit 4-Channel I2C 12-Bit ADC Features:
  • Wide Supply Range: 2.0V to 5.5V
  • Low Current Consumption: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
  • Programmable Data Rate: 128SPS to 3.3kSPS
  • Internal Low-Drift Voltage Reference
  • Internal Oscillator
  • Internal PGA
  • I2C Interface: Pin-Selectable Addresses
  • Can run from 2V to 5V power/logic
  • Measures a large range of signals and is super easy to use.
  • 12-bit precision at 3300 samples/second over I2C.
  • Configurable as 4 single-ended input channels, or two differential channels.
  • Includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range.
  • Breakout Board equipped with ferrites to keep the AVDD and AGND quiet
