JHEMCU EM40A 4-in-1 40A ESC 2-6S LiPo BLHeli_S

The JHEMCU EM-40A 4-in-1 ESC is a compact electronic speed controller designed for multirotors, FPV drones, UAVs and other RC applications. It integrates four 40A ESC channels into a lightweight board, supporting 2S to 6S LiPo batteries. The BLHeli_S firmware provides reliable motor control, while the current-sensing function helps monitor operating current.

With a 20mm M3 mounting pattern and approximately 5.2g weight, the EM-40A is suitable for compact drone builds where low weight and efficient installation are important.
