YouTuber bitluni’s latest incredible build video uses a RISC-V microcontroller with an uncommon driving technique to create a modular magnetic LED matrix.

The LED matrix is an off-the-shelf 8×8 module. Bitluni designed a custom PCB to connect to the matrix. It contains a WCH-IC CH32V208 RISC-V microcontroller and multiple eight-channel drivers for the LED matrix. A 3D-printed enclosure creates a complete module. Bitluni glued magnets into the edges of the enclosure so they could snap together. Pogo-pin connectors (pins on one module, pads on the other) pass power and communication.
