Description
Description
Smallest CH592 module on the planet. The main goal is to create FindMy tags, but any kind of beacon is of course possible.
Only the bare minimum, so a separate programmer with 3v3 supply and usb data lines will be needed to program it. Also the 32k oscillator is omitted to keep the BOM as small as possible.
