AIO F4 2-3S 20A FC V1 BetaFPV

With BB51 ESC solution, F4 2-3S 20A AIO FC V1 is based on BLHeliSuite16714903 with Bluejay ESC software, supports Betaflight bi-directional D-shot and RPM filtering, offers 24KHz, 48KHz and 96KHz fixed PWM frequency. The factory default setting of F4 2-3S 20A AIO FC V1 is 48kHz , and it is not recommended to update to 96kHz, otherwise it may cause the engine idle setting error, no turning after disarming.

Do not flash the firmware in shorter intervals, otherwise there is a risk of jamming and burning the flight controller.

Serial ELRS 2.4 GRAM RX

The ELRS 2.4 GRAM RX series uses the Crossfire serial protocol (CRSF protocol) for communication between the receiver and the flight controller board. So there is a Serial ELRS 2.4 GRAM RX that supports upgrading to ELRS V3 without having to flash the Betaflight flight controller firmware.

• Enter the pairing status by turning the power on/off three times.
• Plug and unplug the flight controller three times;
• Make sure the RX LED flashes quickly twice, which means the receiver is in pairing mode;
• Make sure the RF TX module or RF transmitter has entered the binding state, which sends a binding pulse;
• If the receiver has a constant light, it is related.

Serial ELRS 2.4 GRAM RX can be updated via serial Wi-Fi or Betaflight. Here is how to update Serial ELRS 2.4 GRAM RX firmware via upload.

• Connect your FC to your computer, but do not connect to the betaflight configurator.
• Select the "BETAFPV 2.4 GHz AIO RX" target.
• Flash using the Betaflight Passthrough option in the ExpressLRS configurator.

Connecting external devices

Please note that the board reserves two serial ports and a standard SBUS port, which is available for an external CRSF protocol receiver or GPS module and an SBUS protocol receiver. You can refer to the image below.
