Palm Size Robo Car: SMARS-mini-XL #CircuitPython #FeatherRP2040

114968954 60450480 9e45 11eb 84ad c70d481d8c64

A tiny car built with a Feather, CircuitPython and more. Thanks for sharing!

I’ve been working on a small
wheeled/tracked (if you call rubber bands tracks) robot project for a few
weeks now that is designed around the footprint of your Feather boards. I
haven’t merged my latest work to the main branch yet but in the RP2040
branch there is now a design for a Stemma QT sensor board carrier on the
front of the robot. Having the Stemma QT connector on the Feather RP2040
makes it super easy to change sensors; essentially the core of the robot
(processing, motor controller, power) is hard wired and the rest is modular.

This ‘feather with wheels’ project is up on GitHub, posted by mrjadkowski:

This repository has the 3D models, wiring details, and code for the SMARS mini XL. Currently the code is designed for Circuit Python 6.2.0 running on an Adafruit Feather RP2040. It uses a VL53L0X time-of-flight sensor connected with i2c, an DRV8833 h-bridge motor driver, a small lipo, and a SPST switch. See the Fritzing diagram for wiring
