BetaFPV Air Brushless Flight Controller G4 5IN1 V1.0

Description

The BetaFPV Air Brushless Flight Controller G4 5IN1 V1.0 delivers an unparalleled flight experience with a 55% speed boost, powered by the STM32G473CEU6. Featuring the ICM42688P gyro for precise control, an onboard 25-400mW VTX, and a 16MB black box, it ensures smooth, responsive performance. With ultra-lightweight 4IN1 and 5IN1 versions, seamless ELRS integration, and extensive UART options, this controller is the ultimate choice for ultralight 1S whoop drones.

Features:

• Air Brushless Flight Controller, the first 1S FC that utilizes the G473 processor, experienced a remarkable 55% increase in computing speed and lightning-fast response times for precise racing and complex freestyle maneuvers, surpassing the F411.
• Higher integration yet lightweighter design, featuring a custom miniature OSD chip. Weighing only 2.9g (4IN1 Version) or 3.6g (5IN1 Version), it offers extra UART port options for effortless function expansions, adapting flawlessly to any flight scenario.
• Default integrated onboard 25-400mW VTX. Streamlines installation saves space, reduces weight, and boosts convenience for VTX and FC adjustments. The 5IN1 Version even integrates the Serial ELRS 2.4G RX.
• Elevate your drone’s precision with the industry-leading ICM42688P gyro, integrated accelerometer, cutting-edge sensor calibration, and filtering algorithms, and a sample rate of up to 8K, which takes the drone’s posture and movement accurate and precise drone to the next level.
• Unlock extensive flight data recording and analysis with an impressive up to 16MB capacity black box. Maximize performance and diagnose faults effectively, leveraging the full potential of your drone.

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 V3.0 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.

Connecting External RX/VTX

Please note that UART2 has connected to the VTX by default. This FC reserves 3 complete full-featured serial ports that can be used for external CRSF/SBUS receivers, GPS, HD VTX, or other serial devices. You can refer to the below pictures.
