“The OnOff SHIM working very well with Raspberry Pi 4 and Raspbian Buster.
With an external momentary press button, the best way to power on/off your RaspBerry Pi. But the downloadable Pimoroni SHIM script is unfortunately not released for the newest Raspbian Buster, therefore a customized other solution is necessary. And the power supply connect could be get an update to USB-C for a perfectly solution. The order from Germany and the delivery without any issues.”
