From the project

Bettery switching PCB for wireless Pro-micro based Sofle keyboards

We are triying to make a battery switch for the Sofle Keyboard, or properly said, the nRFMicro or Pro Micro compatible board used by the Sofle Keyboard.

Our goal is to have a PCB that could short and open the baterry supply via a switch, keeping as low profile as possible and doing it as integrated as possible. Also, the device should change the battery in any of the positions, because the nRFMicro has a battery charge monitor.
