Exposed Wirenuts and the TwigGuard Mini
A small hardware company developing compact 1S reverse-polarity protection boards and 18650 power hardware for makers, robots, drones, and portable electronics.
Field notes
TwigGuard Mini is specified as a 16 × 13 mm 1S Li-ion protection board using dual P-channel MOSFETs, with a mechanical interface intended for the company’s 18650 holder system. The homepage says first production boards remain in validation and withholds current ratings until voltage drop, thermal behavior, reverse-polarity response, current sweeps, resistance, and failure margins have been measured. A holder and future 5V single-cell platform are listed as development work.
