Fire-40-a
Fire-40-a is an open source RP2040/RP2350 PCB design by piersfinlayson: a 2-layer, 18.9 × 51.9 mm board with 47 components (24 distinct parts). It is built around the RP2350_60QFN, AP2112K-3.3, USBLC6-2P6, W25Q16JVSS. Filed under retro computing.
The most flexible and powerful ROM replacement for retro systems - using a Raspberry Pi RP2350 microcontroller.
Verified - The "rp2354-and-flash" design has been verified serving a 27C400 16-bit 40-pin ROM on an Amiga A500.
The "rp2354-no-ext-flash" has not yet been verified.
The functionality of the external flash has not been verified. This design has only been tested using the RP2354B with built in flash. While external flash is also present on the tested boards, it has not been verified, or that the design works with an RP2350.
