F4 1S 12A AIO Brushless FC V3, the FIRST flight controller designed specifically for HD VTX. This powerful controller features an STM32F405/AT32F435 chip for high-performance calculations and a 5V 3A BEC solution for the HD VTX. It weighs only 4.2 grams and includes a Serial ELRS 2.4G receiver, 16MB Black Box, Barometer, and Current meter. Designed for HD VTX, it removes the OSD chip AT7456E and also added support for external GPS through Betaflight 4.4.0.


Bullet Point

  • F4 1S 12A AIO Brushless FC V3 is specially designed for HD VTX, the MCU with stronger performance and computing power, and the new BEC solution with 5V 3A output supports HD VTX power supply.
  • Integrate Serial ELRS 2.4G receiver, 16M black box, barometer, current meter, reserve 2 complete serial ports, and 1 standard SBUS. It is compatible with various devices such as GPS, HD VTX, and external receivers, which reduces the overall weight and complexity of the build.
  • With a lighter weight of 4.2g, it improves flight performance and agility.
  • There are 2 main control MCUs available: the STM32F405 and the AT32F435. The AT32F435 has a stronger performance, with a COREMARK score that is even comparable to that of the STM32F722.
