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.
FC 1S 12A AIO FC V3
Bullet Point
- F4 1S 12A AIO Brushless FC V3 is specially designed for HD VTX, with the MCU featuring stronger performance and computing power. The new BEC solution with 5V 3A output supports HD VTX power supply.
- Integrates Serial ELRS 2.4G receiver, 16M black box, barometer, current meter, reserves 2 complete serial ports, and 1 standard SBUS. Compatible with various devices such as GPS, HD VTX, and external receivers, reducing overall weight and build complexity.
- Weighing only 4.2g, it improves flight performance and agility.
- Two main control MCUs available: the STM32F405 and the AT32F435. The AT32F435 has stronger performance, with a COREMARK score comparable to that of the STM32F722.

About ATBetaflight
ATBetaflight is a fork ported to Artery Tek AT32F435/7 based on betaflight 4.3. The biggest difference from the Betaflight firmware is that the sensitivity of the BMI270 gyroscope is optimized, and the measured sensitivity error is reduced from about 2% to less than 0.04%, which is consistent with the specification table in the datasheet. Phenomena such as "horizon drift" and "wrong direction of GPS rescue" basically no longer appear in the actual flight.
The current release of ATBetaflight 4.3.2 RC3 already supports all hardware functions but does not support the new functions or optimization problems of subsequent versions of Betaflight 4.3.1. For more information, please refer to: https://github.com/flightng/atbetaflight
Betaflight Firmware and CLI
For STM32F405 Version
FC firmware: Betaflight_4.4.1_BETAFVF405
For AT32F435 Version
FC firmware: ATBetaflight_4.3.2_BETAFPVF435_RC3
Pay attention, DO NOT flash the other firmware for the AT32F435 version. Betaflight official firmware for the AT32F435 is still in the development process, only the currently released ATBetaflight 4.3.2 RC3 has bidirectional Dshot, PRM, and RGB functions.
If you need to use the Betaflight configurator, please use Betaflight_10.10.0 and follow the steps below to open the "Show all serial devices" in the "Options" first to recognize the port.

ESC Firmware
With BB51 ESC solution, F4 1S 12A FC V3 is based on BLHeliSuite16714903 with Bluejay ESC firmware, it supports bidirectional D-shot and RPM filtering in Betaflight, offers 24KHz, 48KHz, and 96KHz fixed PWM frequency for options, and custom start-up melodies. F4 1S 12A FC V3 default factory setting is 48KHz and it doesn’t recommend upgrading the 96KHz, or it might cause an error in the motor idle setting, not spinning when disarmed.
DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller.
