2. Connection and LED

Diagram of the flight controller PCB. Motor outputs are labeled M1, M2, M3, M4 with rotation directions (CW/CCW). Features include a Blue LED (Armed: solid, Disarmed: off), a Red LED (Power), Buzzer connections (BUZ+, BUZ-), and a Bind button. LED status: Slow blinking indicates 'No RC Input signal'; Solid LEDs indicate 'RC Input signal connected' or 'Binding mode'.

3. Camera connection

Diagram of the camera module. Connections: '+5v out', 'GND', 'Video out', 'Video in'. Includes a 'Boot Pad'. Power input: '1S LIPO Input (Support HV 4.35V)' (Red:VCC, Black:GND). Maximum VTX power is 25mW.

4. Mixer type and ESC/Motor protocol

Diagram showing motor layout (M1-M4). 'ESC/Motor Features' for brushed motors: 'Motor PWM speed Separated from PID speed', 'MOTOR_STOP' (prevents motors spinning when armed), 'Disarm motors regardless of throttle value', 'Disarm motors after set delay [seconds]', 'Minimum Throttle (Lowest ESC value when armed)', and 'Maximum Throttle (Highest ESC value when armed)'. Note: Motor sequence differs from Inductrix; install according to diagram.

5. Receiver configuration

Screenshot of Betaflight configurator 'Ports' tab. UART3 configured for 'Serial RX', 'Receiver Mode' set to 'RX_SERIAL', 'Serial Receiver Provider' as 'SBUS'. Default 'Channel Map' is 'TAER1234', 'AUX 5' for 'RSSI Channel'. Thresholds: 'Stick Low' 1050, 'Stick Center' 1500, 'Stick High' 1900. Warning: Do not disable MSP on the first serial port.

6. Binding procedure

Press and hold Bind button on BEECORE V2.0, then power on (LEDs solid). 2. Release Bind button. 3. Turn on Frsky Radio, select D8 mode, go to Receiver [Bind], and press ENT. BEECORE V2.0 LEDs turn off upon successful binding. Reconnect battery.

7. Firmware update

In Betaflight configurator, select target 'OMNIBUS' and firmware version. 4. Enter DFU Mode (solder boot pad + USB, or flash Betaflight). 5. Use Zadig to replace drivers to WINUSB. 6. Reconnect, open Betaflight, load and flash firmware.
