5. Setup and Installation
The TAKER H743 BT & H80_BLS 80A stack is designed for plug-and-play convenience, minimizing the need for extensive soldering. Follow these general steps for installation:
- Mounting: Securely mount the Flight Controller and ESC stack to your drone frame using the provided M3 screws and silicone anti-shake pads. Ensure proper orientation as indicated by markings on the board.
- Power Connection: Connect the XT90 power cable to the ESC. Ensure correct polarity.
- Motor Connections: Connect your drone's motors to the appropriate motor pads (M1-M8) on the ESC. The stack supports up to 8 motor outputs for X8 configurations.
- Peripheral Connections: Utilize the various direct-connect ports for peripherals. Use the provided cables for:
- DJI Air Unit (via SH1.0 6pin cable)
- Receiver (via SH1.0 4pin silicone cable)
- Camera (via SH1.0-SH1.25 3pin cable)
