Overview:
The HappyModel X14 5-IN-1 AIO Flight Controller is an all-in-one solution designed for lightweight 1-2S FPV whoops and micro builds. Combining a flight controller, 12A 4-in-1 ESC, ExpressLRS receiver and 400mW OpenVTX on a single compact board, it reduces wiring complexity while providing the features needed for high-performance micro quads.
Powered by an STM32G473 processor, the X14 is an upgraded successor to the X12 ELRS PRO, offering additional UARTs for greater flexibility when adding peripherals such as GPS or external devices. The onboard Bluejay 48kHz ESC delivers smooth throttle response, while the integrated OpenVTX supports output powers up to 400mW with SmartAudio 2.1 for convenient channel and power adjustment through Betaflight.
Designed for 75mm and 85mm whoop builds, the X14 includes a serial ELRS 2.4GHz receiver, 16MB Blackbox memory, voltage and current sensing, and a 5V BEC, making it a compact and capable choice for pilots building or upgrading a lightweight FPV quad.
