The RP2040 PMOD is a PMOD-compatible board based on the Raspberry PI microcontroller, the RP2040
The board has its own 3v3 LDO regulator, and the 3v3 pins of the PMOD connector are not connected.

On the /examples folder you will find examples to program in this board.
- pico-uart-bridge: Uses the RP2040 PMOD to generate two different UART interfaces in the PMOD PINS 5/6 and 11/12.
More examples soon!
The RP2040 PMOD is open-source, so you can use the output files to manufacture your own in JLCPCB. You just need to compress the output_files directory, and upload it to JLCPCB.
Remember to change the Surface Finish to LeadFree HASL to make your board ROHS compliant.
Then you have to add the PCB Assembly service and upload the centroid file, and the BOM.
In a few days, you will receive your board at home. If you want just one RP2040 PMOD, contact me.
