There was a problem hiding this comment.
A couple questions about the board_init.
- board_init() no longer deletes code.py or creates main.py: the Elioblocs editor now writes code.py. - The default boot.py explains why the drive is read-only and how to change it. - GPIO15-16 are free pins (no 32 kHz crystal), and the NeoPixel count anticipates the next board revision.

Notes
0x303A:0x8384is allocated to "Eliobot-S3 - CircuitPython" in espressif/usb-pids.board_init()writes a defaultboot.py(storage.remount("/", False)) andmain.pywhenboot.pyis missing, the same approach asmixgo_ce_serial: the robot is programmed from our web editor over the serial REPL or BLE rather than through the drive.Testing
