!!! 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.
