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.

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

Pay attention, DO NOT flash the other firmware for 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.

Serial ELRS 2.4G RX

Serial ELRS 2.4G RX uses the Crossfire serial protocol (CRSF protocol) to communicate between the receiver and the flight controller board. So the Serial ELRS 2.4G RX is available to support upgrading to ELRS V3 with no need to flash Betaflight flight controller firmware. 

  • Enter binding status by power on/off three times.
  • Plugin and unplug the flight controller three times;
  • Make sure the RX LED is doing a quick double blink, which indicates the receiver is in bind mode;
  • Make sure the RF TX module or radio transmitter enters binding status, which sends out a binding pulse;
  • If the receiver has a solid light, it's bound.

The Serial ELRS 2.4G RX can be updated via Wi-Fi or Betaflight serial passthrough. Here is the way to update the Serial ELRS 2.4G RX firmware through passthrough.

  • Plug in your FC to your computer, but do NOT connect to betaflight configurator.
  • Choose target "BETAFPV 2.4GHz AIO RX". 
  • Flash using the BetaflightPassthrough option in ExpressLRS Configurator.

How to flash firmware via Wi-Fi here.

Connecting External RX/HD Digital

Both STM32F405 and AT32F435 version support external HD digital VTX. Please note that the board reserves two serial ports and a standard SBUS port, which is available for the external CRSF protocol receiver or GPS module, and SBUS protocol receiver. You can refer to the below picture.

Based on 4 reviews

for everyone who has problems with SPI ELRS receiver. Turn on UART(3) "Serial RX" in PORTS TAB than in "RECEIVER TAB"; Receiver Mode to "SERIAL (via UART)" than "serial receiver protocol" to "CRSF". Before all those update to latest 4.4.3 BF and make sure to turn on in mane menu in B.F. in tab "OPTIONS"; SOW ALL SERIAL DEVICES (FOR MANUFACTURER OR DEVELOPER) and have fun flying.

BETAFPV Be so kind tu update your directions on website, you guys missing important steps so ppl can do flying instead of spent time figuring out why it dose not work.

Michael Paszkiet

This FC has all the goodies on board you need and works well so far.
But: Even I had no issues myself with this FC, I would strongly recommend to buy the all new FC from BetaFPV the F4 2-3S 20A AIO instead. It can handle LiPo up to 3S, has ESCs with rating of 20A and a better power supply for the O3 unit!!! And lots more for almost the same money.
I installed all my Pavo Picos with the new controller now, and glad I did.

Uscita firmware 4.4 per versione AT32F435

Quando verrà rilasciata la nuova versione del firmware per AT32F435? È possibile installare betaflight 4.4 se si usa una ricevente esterna non spi?

If you plan to use a non-SPI external receiver with the BetaFPV F4 1S 12A AIO Brushless Flight Controller V3, you may need to make some additional settings and configurations. Before installing Betaflight 4.4 or any other version, ensure that you consider the following:

UART Availability: Check the available UART interfaces and types on the flight controller board. If your external receiver requires a UART interface for connection, make sure there are enough available UART ports.

Hardware Connections: According to the requirements of your external receiver, make the correct connections between the receiver and the flight controller's UART or appropriate pins.

Configuration Settings: Once the hardware connections are made, you'll need to make the necessary settings in the Betaflight configuration interface. In the Ports tab, configure the selected UART port as 'Serial RX' to receive signals from the external receiver.

Receiver Type Selection: In the Configuration tab of the configuration interface, select the correct receiver type. If your external receiver is not listed, choose the option compatible with its communication protocol.
