This little pcb is used with the RP2040-Zero which is a small USB Development board powered by the Raspberry RP2040.
This PCB solders directly to the RP2040-Zero and breaks out the various pin and labels them for use in the Nintendo Switch to Dump the Nand. There are 3 resistors with the value of 47 ohms on the DAT0, CMD and CLK allowing for proper NAND dumping.
Please do not email me with help in dumping the nand or any other activity with the use of the development board, this requires you to know what you are doing and I do not provide any information or help in this department.
