Compatibility & Build Notes
Build note 01
90A 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 33.6V, so make sure your cell count and battery plan stay inside that band.
Build note 03
0 available UARTs gives you a rough budget for receiver, GPS, VTX control, and other serial accessories.
Build note 04
4 ESC channels indicate the board is aimed at a standard multirotor layout unless your build plan says otherwise.
