Happymodel X12 ELRS AIO Flight Controller

The Happymodel X12 is a highly integrated 5-in-1 AIO flight controller tailored for ultra-light whoops and toothpick drones. Combining an F411 processor, a 12A ESC, an onboard ELRS 2.4GHz receiver, and an adjustable 400mW OpenVTX onto a single board, it drastically reduces wiring and saves precious grams on micro builds.

Key features

• True 5-in-1 architecture integrating FC, ESC, ELRS receiver, OpenVTX, and OSD
• Supports 1S to 2S LiPo and LiHV input voltages
• Adjustable 5.8GHz video transmission up to 400mW for excellent penetration
• Standard whoop mounting layout for broad micro-frame compatibility
