Just choose them according to your purpose. No need to solder your own parts, very easy to use. 4Double Layer PCB: The expansion board is a double layer board with a pin on both sides. Therefore, the circuit is stable and reliable, and there will be no poor circuit contact and unstable signal transmission. 5Important Note: Only compatible with the 38 pin narrow and no mounting hole versions of the esp32 development board, not applicable to other versions.
