Proper installation is crucial for the safe and reliable operation of your PM07 module. Follow these steps carefully:

1. Iṣagbesori: Secure the PM07 board to your drone frame using the 45x45mm mounting holes. Ensure it is positioned away from sources of electromagnetic interference (e.g., ESCs, motors).
2. Asopọ batiri: Connect your LiPo battery (2S-14S) to the pre-installed XT60 connector on the PM07 module. Ensure correct polarity.
3. Flight Controller Connection: Connect the appropriate JST GH cable from the PM07 module to the power input port of your Pixhawk 4 or PX4 flight controller. Refer to your flight controller's manual for the exact port location. The PM07 provides power and current/voltage sensing to the flight controller.
4. ESC Connections: Connect your Electronic Speed Controllers (ESCs) to the designated output pads or connectors on the PM07 board. Ensure each ESC is connected to its corresponding motor output.
5. Awọn isopọ Agbeegbe: If using additional 5V peripherals, connect them to the available 5V output pins on the PM07, ensuring not to exceed the 3A maximum current rating.
