Compatibility & Build Notes
Build note 01
45A per-channel current handling is a fast way to sanity-check the motor and prop load this board can support.
Build note 02
Power input is published for 7.4V to 25.2V, so make sure your cell count and battery plan stay inside that band.
Build note 03
XT30 power handling means your battery lead and build wiring should match this connector family.
Build note 04
6 available UARTs gives you a rough budget for receiver, GPS, VTX control, and other serial accessories.
