JHEMCU GHF745AIO-50A 4-in-1 ESC (500 X Pack)

The JHEMCU GHF745AIO-50A is a 4-in-1 ESC with an integrated flight controller, on a 30×30 mounting pattern, rated at 50A per channel. The “AIO” designation means the flight controller and the four ESC channels are on one board rather than stacked as two separate units.

Integrating them matters because it removes a wiring loom between the FC and the ESCs — four signal wires and their connectors disappear, and with them four potential failure points in a circuit that sits in the highest-vibration part of a multirotor. It also saves stack height, which is why AIO boards are common on builds where space between the frame plates is tight.

The 50A rating is per motor channel, so the board suits an FPV multirotor with four motors drawing up to that figure each. This listing is a 500-pack at trade quantity — it is intended for a shop, a workshop or a batch build rather than for a single aircraft. The BLHeli_S firmware on the companion listing is the widely used ESC firmware with the standard set of tuning and telemetry features.
