This set of high quality machined header pins can be soldered onto the MicroPython pyboard (all versions), and mate perfectly with both the LCD and Audio modules, as well as the Protoskins. The black pins are used for the standard I/O ports and the 4-way GND rail, and the white pins are used for the 4-way V+ rail and the additional, inner I/O ports. The header pins are female and are compatible with standard 0.65mm square male pins.
