Hummingbird 200 RaceSpec Stack 20x20mm – ELRS FC + 80A AM32 ESC

Build note 01

80A 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 11.1V to 25.2V, so make sure your cell count and battery plan stay inside that band.

Build note 03

7 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.
