Product overview

The iFlight GM2804 expansion board kit includes three GM2804 gimbal motors, one Alexmos 32-bit SimpleBGC control set and matching cables. Its controller is designed for building three-axis camera stabilization systems for UAV mounting and handheld camera stabilizers. This version has no encoder program. Each motor has a 12N/14P configuration and a hollow shaft, with an outer diameter of Φ35±0.05mm, a height of 15±0.2mm and a weight of 42.3±0.2g. The 60±3mm leads use #24 AWG wire and PH3P connectors.

The GM2804 motors use 2~3S power, with maximum power of ≤25W and working conditions of -20~60℃ at 10%~90% RH. The SimpleBGC 32-bit expansion board measures 50×50mm and has 45mm mounting hole spacing with 3mm mounting holes. Its supply voltage is 8-26V with a 3S-6S lithium battery, and its maximum motor current is 1.5A. The board has a 5V output, supplies external equipment with up to 1A, and provides 150mA at its 3V output.
