Measurements:

The integrated dual BEC with 5V 3A and 9V 2A outputs ensures stable and reliable power supply for all connected components. The board is extremely lightweight - weighing only 3.4g, making it perfect for micro 1S drones where minimal weight is important. The convenient plug-and-play socket allows you to directly connect the Blackbox module or GOKU GM10 Nano GPS without complicated installation.

The integrated 2.4 GHz ELRS receiver with TCXO provides a more stable signal, lower latency and better immunity to interference. It is the first 1S AIO controller compatible with O4 and O4 Pro systems, allowing you to connect a VTX without soldering and avoiding the limitations of 1S video transmitters. The STM32F405BGA microcontroller provides up to 30 % higher processing performance than the F411 or G473, making flight control more precise and faster. The motor connectors with plug-and-play sockets allow you to assemble the drone faster and without additional soldering.

The ICM42688P sensor with a separate power supply and 3.3 V LDO regulator reduces gyro interference and increases IMU accuracy, improving flight stability in 1S systems.

The compact 1S AIO design offers full expansion capabilities - the provided contacts allow direct connection of HD VTX, Blackbox and GPS modules. The board supports O4, O4 Pro, Walksnail and HDZero digital video transmission systems.

The board supports O4, O4 Pro, Walksnail and HDZero digital video transmission systems.
