Due to the permanent and potentially destructive nature of soldering and connecting to other devices in general, always remember to test electronics first, before attempting to solder to them or connect any accessories.
For a flight controller, this can always be achieved by connecting to the board via USB and verifying that everything is working via the configurator. To test an ESC, you can power up the board via crocodile clips. We sell crocodile clips here for this very purpose.
Please see the Items requiring soldering section of our refund policy for more information.

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.

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
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.
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 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.
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.
How to flash firmware via Wi-Fi here.
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.
If you want to try the popular ExpressLRS receiver version for long-range performance, highly recommend you check the items for the ExpressLRS series.
