Mauch PL-100 Power Module Sensor Board

The Mauch PL-100 is a premium power module sensor board built for heavy-lift cinelifters, agricultural drones, and industrial multirotors running ArduPilot or PX4. Using a precision Hall-effect sensor rather than a shunt resistor, it measures high current flows accurately without generating excess heat or a voltage drop in the main power line.

Key features

• 100A continuous current sensing based on the Allegro ACS758-100U Hall-effect chip, for large-scale builds.
• Hall-effect design avoids power dissipation and voltage sag under heavy load.
• Delivers clean analogue voltage and current telemetry directly to the flight controller.
• Compact board (27.5 x 19.5 x 10.5mm, 17g), supplied in a CFK enclosure (43.5 x 23 x 15mm, 22g) for extra protection.
• Connects via a Molex Clik-Mate 1.25mm 4-pin plug with 2 x 10cm 12AWG sensor wires.

Specifications

• Sensor type: Precision Hall-effect (ACS758-100U)
• Max continuous current: 100A
• Voltage range: up to 20S (85V) with the solder bridge open; up to 7S (30V) with the solder bridge closed
• Telemetry output: Analogue
• Supported firmware: ArduPilot, PX4
• Weight: 17g board only, 22g in the CFK enclosure (both with 2 x 10cm 12AWG leads)
• Connector: Molex Clik-Mate 1.25mm 4-pin (5023800400); sensor cable not included (it comes with Mauch BECs)
• Sensor supply with a third-party BEC: 4.95-5.05 V

The PL-100 is a dedicated telemetry sensor board — to supply power to a Pixhawk, Cube, or similar flight controller, pair it with a compatible Mauch Premium-Line BEC or Sensor Hub X2-V2.
