RP2040‐Zero - nmanzi/PsNeePIO GitHub Wiki

Overview

The RP2040-Zero is a cheap ($6-7 AUD, less from Ali) and compact RP2040 board with:

• Gobs of GPIO pins (more than we need),
• USB-C for ease of programming and debugging, and
• 3.3VDC GPIO, making it perfect for use as a modchip for the PlayStation.

The board is small enough to fit inside the PlayStation console (I like the space at the bottom right).
