HappyModel ELRS F4 2G4 AIO Flight Controller
The HappyModel ELRS F4 2G4 AIO Flight Controller is a compact, all-in-one board integrating a Betaflight F4 flight controller, a 5A 4-in-1 ESC, a 2.4GHz SPI ExpressLRS receiver, and a 5.8GHz VTX. It is designed for 1S LiPo-powered micro drones, supporting DSHOT600 and real-time telemetry for enhanced flight control.
Features
- Integrated AIO design with F4 flight controller, 5A 4-in-1 ESC, SPI ExpressLRS 2.4GHz receiver, and 5.8GHz VTX.
- Powered by the SX1280 RF chip for extended range, high sensitivity, and ultra-low latency communication.
- Supports 1S LiPo battery input (2.9-4.35V), optimized for ultra-lightweight Tiny Whoop and toothpick drone builds.
- Features an adjustable 5.8GHz VTX with power output selectable from 25mW to 200mW across 40 channels.
- Equipped with Betaflight OSD, DSHOT600 protocol, and telemetry support for real-time flight data feedback.

The HappyModel ELRS F4 2G4 AIO Flight Controller consolidates critical drone systems into a single, space-saving unit. Its core is a Betaflight-compatible STM32F4 processor paired with an MPU-6000 gyro for stable flight control. The integrated 5A 4-in-1 ESC supports DSHOT600 for precise, high-speed motor control, while the onboard SPI ExpressLRS receiver leverages the SX1280 chipset for robust 2.4GHz RF performance with configurable packet rates from 25Hz to 500Hz.
This board is engineered for minimalistic, high-performance micro builds. The built-in 5.8GHz video transmitter offers adjustable output power, allowing pilots to balance video range with flight time. Its direct 1S LiPo compatibility eliminates the need for voltage regulators, reducing weight and complexity for the most compact FPV drones.
