F411ELVTX with STM32F411 processor, ICM42688-P gyroscope, integrated OSD, built-in 5V/1.5A BEC, built-in standalone ELRS 2.4G receiver, built-in VTX 5.8G 400MW image transmission module, and support for brushless ESC quads with 1-2S 12A. The board has no black box or barometer module. If you choose 1S power supply and have difficulty in starting the motor, please adjust the starting power value to the appropriate increase to the value that can be started. The AIO's mapping does not have Low Power Disarm enabled by default (which can be interpreted as: unlocked mapping is the maximum power, locked mapping is the minimum power, which can reduce the temperature of the PCB when tuning the machine). If you do not use the built-in ELRS can also support external SBUS receiver.
