1. The PCB is highly integrated and the overall solder joints are relatively small. 2. JHEMCU F411ELRS uses STM32F411 processor, ICM42688-P gyroscope, integrated OSD, built-in 5V or 1.5A BEC step-up and step-down circuit, and built-in 9V or 2A BEC step-up circuit to provide a stable 9V output for the image mission socket. 3. There will be no black screen when using the high-definition air unit on the 2S. It has a built-in independent ELRS 2.4G receiver and supports four-channel 1-2S 12A brushless ESCs. 4. This circuit board has no black box and barometer module. If you encounter difficulty in starting the motor if you choose 1S power supply, please increase the starting power value to a value that can be started. 5. If you do not use the built-in ELRS, you can also support an external SBUS receiver. You need to short-circuit the SBUS short-circuiting pad to shield the ELRS receiver function integrated on the AIO. 1. Model: JHEMCU F411ELRS 2. Main control chip: STM32F411CEU6 (100MHZ, 512K) 3.
