Raw Blame History

  • x1 Raspberry Pi Pico board with soldered pins.

  • x1 USB-A to Micro-USB cable.

  • x10 dupont wires female-female.

  • x1 1N5819 diode. It's optional but strongly recommended. Any similar one will do.

    !!! warning The diode is needed to provide power to the Pico HID regardless of the target host state, which prevents the backpowering problem. It will allow you to keep the keyboard buttons pressed during the target host power cycle, which is, for example, important for MacOS to get into the boot menu.

      Do not connect the red wire (the `VSYS (Pico) -> 5V (Pi)` line) without a diode.
  If you can't find a diode, don't connect this wire at all.
