Holybro PM07 14S Power Module with 8-ESC Distribution

The Holybro PM07 is a power module and ESC power distribution board in one, for Pixhawk-class autopilots. It takes a 2S–14S battery, feeds the flight controller clean 5.2 V, reports battery voltage and current, and splits power and signal to up to eight ESCs, which makes it the natural partner for the Pixhawk 6C and Pixhawk 4, as neither has servo-header pins of its own.

Key features

• Two 5.2 V outputs on independent circuits and BEC ICs, for redundant flight-controller power
• Analog voltage and current sensing to the FC over a 6-pin JST-GH cable, reading up to 120 A
• PCB rated 90 A continuous and 140 A burst (under 60 seconds)
• Power and signal distribution for up to 8 ESCs
• Arrives with the XT60 battery lead and a 220 µF 63 V capacitor already soldered, plus the JST-GH cable set

Specifications

• Input voltage: 2S–14S LiPo
• Continuous current: 90 A (PCB)
• Burst current: 140 A, under 60 s
• Current sensing: up to 120 A
• FC power output: 5.2 V, 3 A max
• Voltage divider: 18.182
• Amps per volt: 36.364
• Battery lead: 80 mm, 12 AWG, XT60
• Dimensions: 68 × 50 × 10 mm
• Mounting holes: 45 × 45 mm
• Weight: 43.8 g
• In the box: PM07 board, XT60 lead and 220 µF 63 V capacitor (installed), 2 × JST-GH 10-pin, 1 × JST-GH 8-pin and 2 × JST-GH 6-pin cables

The fitted XT60 and 12 AWG lead are rated 30 A continuous and 60 A burst (under 60 seconds), well below the board's own rating, so heavier builds should switch to a larger connector and thicker wire. The PM07's sensing is analog and does not work with the Pixhawk 5X or 6X, which need a digital module such as the PM02D.
