BETAFPV Matrix 1S Brushless Flight Controller (5IN1)

Diagram

Below is a diagram of the Matrix 1S Brushless FC.

Matrix 1S, F4 1S 5A AIO and Air 5IN1 comparison

The Matrix 1S Brushless FC is designed for beginners, offering improved durability and performance compared to the original F4 1S 5A AIO FC. The 1mm thick board is more robust than the 0.8mm thick F4 1S 5A AIO board, and the built-in motor switches simplify installation, eliminating the need for soldering. With the advanced G473 processor and 5IN1 configuration, including a 5.8GHz 400mW VTX, the Matrix 1S is a better choice for beginners.

For experienced pilots seeking an ultra-lightweight and race-ready experience, the Air Brushless FC 5IN1 version is the best choice.

Serial ELRS 2.4G RX uses Crossfire protocol (CRSF protocol) to ensure communication between the receiver and the flight controller board. Therefore, Serial ELRS 2.4G RX can be upgraded to ELRS V3.0 without the need to reflash the Betaflight flight controller firmware. Enter pairing mode by turning the power on/off three times.

1. Connect and disconnect the flight controller three times;
2. Make sure the RX LED is blinking quickly in double flashes – this means the receiver is in pairing mode;
3. Make sure that the RF TX module or radio transmitter has entered pairing mode and sent a pairing pulse;
4. If the receiver lights up steadily, it is paired.

The Serial ELRS 2.4G RX can be updated using Wi-Fi or Betaflight serial passthrough. Here is how to update the Serial ELRS 2.4G RX firmware via passthrough:

1. Connect the flight controller to the computer, but DO NOT connect to the Betaflight configurator;
2. Select the target "BETAFPV 2.4GHz AIO RX";
3. Overwrite using the BetaflightPassthrough option in the ExpressLRS Configurator.

Betaflight software and CLI

The official Betaflight developers recommend using the 42688 gyro version, and many of the issues with the ICM42688 have been fixed in version 4.5.0. For more information, see version 4.5.0.

• FC software: Betaflight_4.5.0_BETAFPVG473, Download the software and CLI file.

Bluejay ESC software

Using the BB51 ESC solution, the Air Brushless flight controller is based on the A_X_5_96KHz_V0.19.hex file for the BB51 Bluejay hardware platform. It supports D-shot300, D-shot600, and even RPM filtering in Betaflight. It also offers 24kHz, 48kHz, and 96kHz fixed PWM frequency options, as well as the ability to use custom start-up melodies.
