RE: your "webrepl_client.py": Circuitpython 8.0 beta Web Workflow support may overlap... https://forum.micropython.org/viewtopic.php?f=18&t=12952 (If I can just get the ESP32-C3-01M-Kit to work with Circuitpython, crazy symtom is the RGB softly glowing white) A fix others mentioned for Arduino seria...

A fix for the Arduino serial monitor disabling the board (/Enable Wired to RTS on some boards) One can patch the Arduino boards.txt file, replacing false with true: esp32c3.serial.disableDTR=true esp32c3.serial.disableRTS=true This worked on my MacOS system where the USB interface has 2 instances: /...

As far as the 1st LED being stuck green mentioned elsewhere, they are pushing the margins powering the array with 3.3v (separate regulator for the cpu) while commonly done for a single on board indicator, a full array generally is powered by 5V in order to get full color fidelity, blue and green LED...

Using a little code trickery they are providing easy browser page based editing... (Circuitpython 7 has BT programming for ESP32s (Which can't mount normally used USB drive image) but it proved to be a bit cumbersome. This beta 8 preview discusses Web Workflow, for 13 minutes, starting here: https:/...

Pimorini may have inspired by the original Pi Pico PIO Hub-75 C example. https://github.com/raspberrypi/pico-examples/tree/master/pio/hub75 It's doing inline PIO (FPGA like) assembly to handle the PWM modulation of each pixel, offloading the CPU from bit-banging. For some IO intensive tasks the RP20...

In case you have left over solar cars. You can make them a bit more interesting for the kids by adding preset steering, so it can do other than a boring straight line.
