iCE40HX1K 64x32 ICND1065L RGB panel with double-buffered SRAM and 2 Mbaud UART image upload

Development snapshot, 2026-09-25. NOT FOR MANUFACTURE.

A custom two-layer 88 x 46.1 mm controller for the tested 64 x 32 ICND1065L LED panel. Bare RP2040, 8 MiB flash, vertical USB-C, non-isolated RS-485, W5500 Ethernet and a vertical HanRun HR963380AE integrated-magnetics jack. KiCad 10.0.6 project, 103 components. The custom PCB has not been fabricated or tested; the working YD-RP2040 module firmware is a separate result.
