Pi 3 - Recommended Noob Robotics Hat?

Wed Nov 23, 2016 10:53 pm

Hello all,

What is the consensus right now for a nice robotics hat to start off with, on a budget? I would like to make a WIFI controlled car/robot and this is my first attempt, so any advice is appreciated.

I was hoping for a board that had it's own motor-driver outputs, preferably the stepper motor kind (although I may not know what I'm talking about). Built in GPIO circuit protection would be great as well but not critical.

I would also be open to a "kit", just as long as the kit wasn't completely prebuilt. I want a little freedom to learn and improvise myself.

See:

Pi Droid Alpha

- on-board L293D motor driver for gear motors
- 6 GPIO's 5V safe (8 if not using the motor drivers)
- 12 5V I/O's from an on-board I/O expander (16 if not using the motor drivers)
- 8 channels of 10 bit analog to digital converters, 0-5V in, from on-board ADC
- easy to use Python API

Sample robot built with Pi Droid Alpha: http://www.mikronauts.com/robot-zoo/hobbit/

If you go to the links above, you will find links in the upper left corner for ordering kits from Ebay or Tindie from me.

For more advanced robots there is RoboPi, but RoboPi does not have on-board motor drivers.

4tronix ( http://www.4tronix.co.uk/store/ ) have a range of Raspberry Pi compatible robot controllers, including at least one HAT.

Pimoroni have some kits and hats, https://shop.pimoroni.com/products/explorer-hat https://shop.pimoroni.com/search?type=product&q=robot
Adafruit has some kits and hats too, https://www.adafruit.com/products/2939 https://www.adafruit.com/categories/34

I have an explorer pHat mounted to a Pi Zero but haven't done much with it yet. I need to buy some more parts to get going.
