===== Introduction =====
\\ 
The RP2040-Zero mini development board is equipped with a Type-C female port, utilizes the RP2040A developed by Raspberry Pi as the core, and leading out all unoccupied pins in a very small form factor. Using castellated processing technology, it can be welded onto your custom board.
