    You'll need to do some light through-hole soldering to attach the headers onto the HAT circuit board. If you would like to stack multiple HATs onto one Pi, you can also pick up a 2x20 stacking header and a set of right-angle 3x4 headers that should be soldered on instead.

    Please note! This kit does not come with Raspberry Pi, servos, or required 5V power supply.

  • 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.

  • MegaPi Born to Motion Control (MegaPi)

    Please note this item only includes the MegaPi board. Servos, motors etc is for demonstration purposes only.

    What is MegaPi?

    MegaPi—Born to Motion Control

    MegaPi is a microcontroller board based on ATmega2560. With abundant motor driver interfaces, it can control and combine different kinds of motors rapidly, drive 10 servos and 8 DC motors/ 4 stepper motors simultaneously and have a maximum output current of 10A.

    MegaPi can be programmed with Arduino software (IDE) or graphical programming language. It is even better that MegaPi works perfectly with Raspberry Pi, by which makers will be able to drive motors and sensors with Python!

    With strong motor-driving ability and ease of use, MegaPi is an ideal option for 3D printer, CNC, robotic project etc.

    How to Use MegaPi?

    Take it easy! It is quite easy-to-use though with great capabilities. If you are a fan of Arduino or Raspberry Pi, we believe that controlling Mega Pi will be a piece of cake to you, since you must know Arduino IDE or Python programming very well. (Controlling MegaPi through Python programming requires a Raspberry Pi, and you have to weld their communication interfaces together.)

    Graphical Programming

    We also prepare graphical programming for the beginner of Maker, making creating robot very easy. We even add the control program of MegaPi into our App, which enables you to control MegaPi with iPad! As congeneric products, MegaPi also need to control motor by motor driver. However, the driver interfaces of MegaPi are encapsulated and anti-reverse, so that you can insert or pull out driver module conveniently.

    Driver modules types:

    • Stepper motor driver: http://makeblock.com/megapi-encoder-dc-motor-river

    • DC/coding electric motor: http://makeblock.com/megapi-stepper-motor-driver-v1

    Thus, don't forget to buy motor driver if you intend to do some projects with motor. We prepare some instructions :

  • ModMyPi PiOT Relay Board (MMP PiOT relay)

    Raspberry Pi board not included

    The ModMyPi PiOT (Pi of Things) relay board is smart! Not quite Skynet smart, so you can tell John Connor to stay at home and play with his Raspberry Pi. But it's much smarter than your average relay board! We've created a Raspberry Pi Relay Board that does away with the complicated wiring and fiddly jumper configuration of your standard relay board, and bundles that control into an on-board PIC, making configuration faster, easier and safer. The PiOT relay board can be connected directly on top of the Pi, or via a GPIO ribbon cable (not included), and also features mounting points for the Raspberry Pi Zero. Each is board is fully assembled, and ready to plug and play! We also stock cases for the Raspberry Pi B+/2/3 & Raspberry Pi Zero.

    The PiOT relay board allows you to bond a GPIO pin to a relay with the touch of a button. No need to tie pins using resistors, and no need to re-wire the circuit when you want to change which GPIO pin fires which relay. Simply select your GPIO pin using the on-board tactile buttons and two-digit 7-segment display, and switch that pin high or low to fire your designated relay!

    The on-board display can be configured to show the Pi's BCM or Pin number system for GPIO/relay bonding, and also demonstrates visual feedback of the relay on/off status for easy monitoring. The display can also be used to test relays before configuring them with your Pi, in addition to providing menu access for setting configuration.

    The PiOT relay board also features multiple innovative start-up modes designed to combat "chatter" on the GPIO which can lead to unexpected behavior. Variable delayed start-up allows users to pause activation of the relays for a short period during boot, ensuring that GPIO pins are correctly set prior to use, or the alternative handshake mode utilises a specific pulse train to enable activation and de-activation of the relay board at the user's will. No more accidental switching of relays at boot!

    The PiOT relay board uses low current (~100mA) PWM (pulse width modulation) to significantly reduce the current required to hold the relays on when compared to other relay boards. This means that relay boards can be stacked up to 5 high without requiring additional external power.

    Warning! Relays can be used to switch large voltages and currents. Please, please, please be careful when undertaking any work with this type of power - it can kill!

    The ModMyPi PiOT Relay Board Features:

    • 4 x OMRON G5LA-1 Relays for Switching up to 10A @ 250VAC, or 10A @ 24VDC
    • 4 x Tactile Buttons for GPIO/Relay Bonding
    • Two-Digit 7 Segment Display for Visual Feedback & Setting Control
    • Micro-controlled GPIO/Relay Setting & Switching (No Jumpers Required!)
    • 40 Point Raspberry Pi GPIO Modelled Input
    • 5V & 3.3V Input Compatible
    • Low Holding Current via PWM ~ 100mA per Relay Board
    • Stackable Relay Board (Up to 5 Without External Power)
    • Multiple Start-Up Modes to Negate Boot GPIO Chatter (Delayed/Handshake)
    • Pi Zero Mounting Points

  • Pi Supply Gert VGA 666 Hardware VGA for Raspberry Pi (Gert VGA)
    PLEASE NOTE: SOLDERING REQUIRED - Loose componets kit form
    Raspberry Pi Not Included


    The Gert VGA 666 (6 bits per colour channel, hence 666) is a breakout/add on board for the Raspberry Pi Model B+,Pi 2 B and Pi 3 B (will not work with Model A/B as the additional GPIO pins are required). It is an open source hardware design recently released publicly by Gert van Loo who was one of the hardware engineers that was instrumental in the initial design of the original Raspberry Pi (also one of the chip architects on the BCM2835 chip at the heart of the Raspberry Pi) and someone that many of you may have spoken to at Raspberry Jams or on the Raspberry Pi forums. This was announced on the Raspberry Pi website and the full design files, schematics and other details are available onGitHub.

    The Raspberry Pi has an HDMI port to connect a display. If your monitor only has VGA, you have to use an adapter. Because this requires a digital-to-analogue conversion, those adapters can be quite pricey, and they can draw lots of power. So our friend Gert van Loo  has created a VGA adapter that uses the Pi’s GPIO.

    This wasn’t possible on the Model A or B, but now the B+ and newer models exposes 40 GPIO pins, there’s more to play with. As well as just allowing you to connect a VGA monitor natively, it also means you can use it as a secondary monitor alongside HDMI. And unlike composite video, the DPI interface can be run independent of the HDMI. The software for dual screens is still under development, but we expect that to arrive in the next couple of weeks. Running two screens at maximum resolution will consume SDRAM bandwidth, and is yet to be tested. (And there’s a catch: as the board uses most of your GPIO pins, you lose access to them.)

    The VGA output supports the same resolution as your HDMI one: from 640 x 480 up to 1920 x 1024 at 60fps. At the highest resolution the pixel quality is almost as good as HDMI. The adapter uses a simple resistor ladder network as a digital-to-analogue converter, so the colour quality depends on how well-balanced your resistors are. There is slight colour banding, and with 6 bits per channel you have a maximum of 262144 colours.

    Dom has been working on the software side and the new DPI (read: VGA) driver software has been added to the latest release.

     

  • PiBorg - PicoBorg - Motor Controller (Picoborg motor controller)

    The PicoBorg is an ultra compact motor controller for the Raspberry Pi. With PicoBorg, you can turn on and off fans, motors, solenoids or relays from your Raspberry Pi. There are 4 low side drivers, so you can turn on and off 4 devices, and one device is connected to the RPi PWM pin, so you can vary the speed of that motor! Motor control is accessed via a simple GUI, which can be installed by following the PicoBorg installation instructions. Motor power is not taken directly from the Raspberry Pi, so there's no risk of your Pi dropping out. Instead, the PicoBorg utilises a battery pack to drive the motors; meaning you're not restricted to 5V motors, in fact you can drive ANY motors up to 20V! Why not create your own Raspberry Pi Cyborg?

    The PicoBorg is perfect for any small motor project, for example:

    • 4 fans on/off control over all and vary speed on one fan
    • 4 solenoids
    • 4 DC motors (on / off control over all and vary speed on one motor)
    • Control one 6 wire stepper motor in both directions
    • Rover project!

    The PicoBorg Features:

    • Drive 4 x DC Motors (on/off) or 1 x 6-Wire Stepper motor (Bi-Direction)
    • Allows speed control on 1 x Motor
    • Max 20V recommended 12V or less
    • Max current 2.5A (stall) or less
    • Primarily designed to be used with large resistance, low inductance motors and for learning and experimenting purposes.
    Warnings:
    • As there are no pull up or pull down resistors on the inputs, the picoBorg expects the Pi to be controlling the pins when the power is applied. Power the Pi first, run the software and then apply power to the PicoBorg.
    • There is no thermal shutoff, keep an eye on temperature of the FETs and diodes
    • There is no current limiting, you must observe current restrictions
    • There is no short circuit or reverse voltage protection
    • For commercial applications and control of larger motors and lower resistance coils etc, PiBorg or PiBorg nano may be a better solution
    • If you are new to electronics and getting started, we recommend you don't use a battery, rather a low current <100mA power supply as this can be more forgiving if you get things wrong
    • Be very careful of connections and soldering as mistakes could potentially hurt your picoBorg and Raspberry Pi.
