Fire-28-d
Fire-28-d is an open source RP2040/RP2350 PCB design by piersfinlayson: a 2-layer, 18.9 × 36.6 mm board with 46 components (20 distinct parts). It is built around the RP2354B, 28 Pin ROM, 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-28-c - 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-28-c - the two connector orientations are complementary.
Has components on both sides of the board.
