Product overview
The Holybro PM07 combines power regulation, battery monitoring and ESC distribution in a board measuring 68*50*10 mm and weighing 40.3g, with mounting holes spaced 45*45mm. It supplies regulated 5.2V from the battery to the flight controller and carries analog current-consumption and battery-voltage measurements through a 6 Pin JST-GH cable. Power and signal distribution accommodates up to eight ESCs. Designed for controllers without built-in servo header pins, including Pixhawk 6C and Pixhawk 4, its internal connections route FMU PWM-IN to FMU PWM-OUT for servos and I/O PWM-IN to M1-8 for motors.
The supplied configuration includes pre-soldered wires, a capacitor and an XT60 connector. Battery input is 2~12S, maximum current sensing is 120A, and the listed 5V output current is 3A. The PCB carries a 90A continuous rating and a 140A burst rating for less than 60 Sec, while the supplied XT60 plug and 12AWG wire are limited to 30A continuous and 60A instantaneous for less than 1 minute. Higher currents require changing the plug type and wire size.
The PM07 does not supply servo power through the FMU PWM-OUT positive and negative pins. For plane or rover installations, the eight-pin positive rail needs a separate supply to drive servos such as rudders and elevons. Supported supply arrangements are a BEC-equipped ESC, a standalone 5V BEC or a 2S LiPo battery. The ADC rail also depends on external power: its 5V output comes from the flight controller’s CAP&ADC port, which is absent on some flight controllers.
