Fire-24-g
Fire-24-g is an open source RP2040/RP2350 PCB design by piersfinlayson: a 2-layer, 18.3 × 31.3 mm board with 44 components (20 distinct parts). It is built around the RP2350_60QFN, 2332/2364 SOCKET, AP2112K-3.3, USBLC6-2P6. Filed under retro computing.
The most flexible and powerful ROM replacement for retro systems - using a Raspberry Pi RP2350 microcontroller.
An upright USB-C variant of fire-24-f - the connector sticks up out of the board rather than lying flat, which helps where there is too little room at the edge of One ROM to plug in a cable. It is not preferred over fire-24-f - the two connector orientations are complementary.
