JHEMCU F411ELVTX 1S-2S AIO Flight Control/ ELRS Receiver / 12A 4in1 ESC / 48CH 0-400mW VTX 25.5MM Hole For FPV Racing Drone

JHEMCU F411ELVTX, using STM32F411 processor, ICM42688-P gyroscope, integrated OSD, built-in 5V/1.5A BEC, built-in independent ELRS 2.4G receiver, built-in VTX 5.8G 400MW image transmission module, support 1-2S 12A brushless ESC quad. The board does not have a black box and barometer module. If you choose 1S power supply and encounter difficulties in starting the motor, please adjust the starting power value to an appropriate increase to the value that can be started. The AIO video transmission does not have the Low Power Disarm function enabled by default (it can be understood that the unlocked image transmission is the maximum power, and the locked image transmission is the minimum power, which can reduce the temperature of the PCB during switching). If the built-in ELRS is not used, an external SBUS receiver can be supported.
