Note: this product requires two 14500 batteries to work, which are NOT included and should be purchased separately. Even though the battery holder fits the normal AA batteries DO NOT USE THEM! A 14500 lithium cell is identical in shape and size to a standard AA battery. But that is where the similarities end. AA supplies 1.5V each where 14500 supply 3.7V each.

This robot chassis is designed to be used with our Explorer HAT, Explorer HAT Pro, or Explorer pHAT boards though it will work with other motor drivers!
The kit is a great way to introduce yourself to robots and controlling motors with your Raspberry Pi. It even includes a camera mount so your little robot can take pictures while it's roaming around!
There is no soldering required and the whole kit can be put together with a small flat-head screwdriver.
Connor Plant has created a build video here: https://www.youtube.com/watch?v=jHn3ZiPG69w
Kit includes:
- Laser cut chassis
- Raspberry Pi camera mount
- 2 x super-grippy moon-buggy wheels
- 2 x push header motors (298:1 ratio)
- 0.5" front castor wheel
- Jumper leads
- 2 x motor mounting brackets
- 2 x battery clips (battery optional and not included)
- Nuts, bolts, and other fixings
Build up your robot and program it in Python, Scratch, or whatever language you prefer! Add a USB battery pack (not included) and a WiFi dongle and you can make it roam free!
Does not include the Raspberry Pi, Raspberry Pi Camera, or Explorer HAT (Pro or pHAT).
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!

How to Control a Stepper Motor using your Raspberry Pi & the ULN2803 Driver Chip
Please note: Raspberry Pi not included
The Explorer HAT and Explorer HAT Pro are the perfect prototyping side-kicks for your Raspberry Pi!
We've added a heap of useful input and output options that will take your projects to the next level. Great for driving motors, using analog sensors, interfacing with 5V systems, and touch (even fruit based!) interfaces.
It's compatible with Raspberry Pi 2, Pi 3, B+, and A+ and comes fully assembled.
Features:
- Four buffered 5V tolerant inputs
- Four powered 5V outputs (up to 500mA!)
- Four capacitive touch pads
- Four capacitive crocodile clip pads
- Four coloured LEDs
- PRO ONLY Four analog inputs
- PRO ONLY Two H-bridge motor drivers
- PRO ONLY A heap of useful (unprotected) 3v3 goodies from the GPIO
- A mini breadboard on top!
5V tolerant inputs - Hook up your Pi to accept input from 5V systems (like Arduino Uno/Leonardo or 5V Trinkets). We've used a 5-channel buffer that will accept anything from 2V-5V as logic high.
5V powered ouputs - The onboard darlington array can supply up to 500mA per channel (but you'll be limited to driving around 1A total from the board). Ideal for stepper motors, solenoids, and relays.
Eight capacitive inputs - Four along the front edge for touch input (labelled 1, 2, 3, 4) and four up the side for attaching crocodile clips to objects (such as fruit, or tin foil) for experimentation!
Four coloured LEDs - Independently controllable LEDs (red, green, blue, and yellow) that make great status indicators.
Four analog inputs (pro only) - A tidy way to integrate analog signals into your project.
Two H-Bridge motor drivers (pro only) - Drive two 5V motors bidirectionally with up to 200mA per channel. Ideal with our micro-metal gear-motors to create the perfect little buggy! You can even soft-PWM for full speed control.

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 capability, a 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.
