Product overview

The iFlight iPower GM4108 expansion board combo set without encoder firmware brings together GM4108 gimbal motors and an Alexmos 32-bit SimpleBGC controller set for three-axis camera stabilization. Its controller supports systems mounted on UAVs as well as handheld camera stabilizers. The package contains three GM4108 gimbal motors, one Alexmos 32-bit SimpleBGC controller set and one matching cable set, providing the motor, controller and cabling components for a camera stabilization assembly.

The GM4108H motor uses a 24N/22P configuration and a hollow shaft, with an outside motor diameter of Φ47±0.05mm and a height of 22.7±0.2mm. Each motor weighs 124±0.5g and has 265±3mm leads in #24 AWG wire with a 2.5mm Dupont connector. Working voltage is 3~5S, maximum power is ≤25W, and working conditions are -20~60℃ at 10%~90%RH. At 20V and 1.5A under load, torque is 1200~1800g·cm. Rotation is clockwise when viewed from the shaft extension end.
