Smaller, faster follow up to the Toepler, built on an RP2040 and programmable in Arduino or CircuitPython. USB-C and all interfaces sit on the front panel so you can reflash without pulling the module. Sold as a PCB set with the SMD parts already assembled, so you supply jacks, pots, buttons, RGB LEDs and headers.
