BetaFPV F405 1S 12A AIO Brushless FC V3 Serial ELRS 2.4G

Description

F4 1S 12A AIO Brushless FC V3, the FIRST flight controller designed specifically for HD VTX. This powerful controller features an STM32F405. 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.

• 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.

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.
