Comparison
The F4 1S 12A V3 FC is specifically designed for HD VTX and features an upgraded STM32F405/AT32F435 chip for high-performance calculations. It also includes a Serial ELRS 2.4G receiver for increased range and reliability, as well as a 16MB Black Box for easy flight data recording and analysis. These upgrades aim to enhance the overall flying experience for pilots.





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
Reference link:
https://github.com/betaflight/betaflight/releases/tag/4.4.1
For AT32F435 Version
FC firmware: ATBetaflight_4.3.2_BETAFPVF435_RC3
Reference link:
https://github.com/flightng/atbetaflight/releases/tag/v4.3.2-rc3

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.

Turn off telemetry in the Betaflight configurator.



Power cycle, while holding the Boot button to put the ELRS receiver into the bootloader.



Open the Betaflight configurator, exit DFU mode, and make sure the Betaflight is disconnected from the flight controller.
Choose target "BETAFPV AIO 2400 RX". Flash using the Passthrough 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.
