“This does what it says on the packet, but yep, my pi4 browns out with a polysync 20 mic/speaker plugged in. Surely power to the usb could be turned on only after the pi has booted? Also the script to set things up is a bit complex to read so yep; just ran it and assumed that someone at pimoroni had checked it.”
“Fitted one to a Pi-Zero based Pi-Star digital voice hotspot. It works well, and so far, no adverse effects of the installer on the Pi-Star software/firmware.
Another was fitted to an original R-Pi B+ (with the 26 pin header) no problems at all.
Gave one to a friend, no feedback yet, the two others "waiting in the wings."”
