An Australian-designed family of I²C boards for battery-powered machines, combining hot-swap power, servo drive and sensing on a shared four-pin bus.

For
Makers building battery-powered machines
Worth noticing
The first board is listed for 25 October 2026 at AUD $59; the servo driver is marked “Coming soon.”

Field notes

The shared connector uses the JST-SH 1.0 mm format and the same pin order as Qwiic and PiicoDev. Address jumpers allow multiple boards of the same type on one bus, while configurable pull-ups account for hosts that already provide them. The page identifies the project as designed in Australia and links to separate sites for each board’s technical details.
