Tfr9
Tfr9 is an open source RP2040/RP2350 PCB design by strickyak: a 4-layer, 82.8 × 62.8 mm board with 106 components (31 distinct parts). It is built around the RP2350B, HC-1.0-3PWT, C427602, W25Q128 and more. Filed under dev boards & breakouts.
The TFR/9 Single Board Computer for Hitachi 6309E or Motorola 6809E CPUs (TFR/901)
This is an RP2350B Dev board that breaks out all 48 GPIO pins.
It follows the original footprint of the RP2040 dev board, but adds 10 pins on each side.
It is not pin compatible with the original RP2040, though a version that shares the same pinout, at least for the first 20 pins on each side would be interesting.
The production files for JLCPCB are in the 'production' directory.
