The HappyModel Diamond 1S F4 AIO (all-in-one) Flight Controller is a compact and lightweight AIO flight controller solution for small drones and racing quads. It is designed to be used with 1S (3.7V) LiPo batteries and features an STM32F411 processor and a variety of sensors and peripherals.
The flight controller is equipped with an F4 processor and an 8-bit 4-in-1 ESC (electronic speed controller), which allows for precise control of the motors. The 4-in-1 ESC also helps to reduce the size and weight of the overall flight controller stack, making it a great option for racing and freestyle quads.
The Diamond 1S F4 flight controller also features a built-in 400mW VTX (video transmitter), which allows for real-time video transmission from the drone. This feature is particularly useful for racing and freestyle pilots, who rely on video transmission to navigate and perform aerial maneuvers.
The flight controller also comes with an ELRS (Event-Based Real-time Scheduler) SPI receiver, which provides a high-speed data link between the flight controller and the receiver. This allows for low latency and high-precision control of the drone.
The HappyModel Diamond 1S F4 AIO Flight Controller is a great option for pilots who want a compact and lightweight flight control solution that can handle high-speed and high-performance flight. It also provides a built-in VTX and ELRS SPI receiver which makes it a complete package for pilots who are looking for a ready to fly solution.
