JHEMCU F411ELVTX adopts 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, and supports 1-2S 12A brushless electric tuning four channels. This circuit board has no black box or barometer module. If you encounter difficulties starting the motor when using 1S power supply, please adjust the starting power value to an appropriate value that can be started. The image transmission of this AIO does not have the Low Power Disarm function enabled by default (which can be understood as: unlocking the image transmission is the maximum power, locking the image transmission is the minimum power, which can reduce the temperature of the PCB during machine adjustment). If the built-in ELRS is not used, external SBUS receivers can also be supported.
