The JST GH is a compact 1.25mm pitch wire-to-board connector that has become the standard interface for flight controllers, GPS modules, and sensor boards in the drone and robotics industries. Its adoption as part of the Pixhawk connector standard (used by ArduPilot and PX4 autopilot firmware) has made the GH series one of the most important connectors in unmanned systems. The GH connector features a top-entry design with a secure-lock mechanism that prevents vibration-induced disconnection — a critical requirement for UAVs. Available in 2 to 15-pin configurations with contacts rated at 1 amp, the GH series accepts 30–26 AWG wire and is available in both crimp and pre-assembled cable formats. Its 1.25mm pitch provides good density while remaining hand-serviceable for prototyping and field repairs.
