The Mauch 073 HS-100-LV is a precision 100A current measurement sensor board based on the Allegro ACS-100U Hall sensor. It is optimised for batteries up to 6S and gives accurate current and voltage data for Pixhawk-based UAVs.
The listing says it enables reliable power monitoring and telemetry in demanding flight applications, using high-quality 12AWG wiring for low-resistance current flow and a stable, noise-free measurement.
The board is compact and requires an external BEC power supply for operation, and it suits both professional and hobby UAVs.
100A current measurement: Hall-effect technology.
Allegro ACS-100U: a proven current sensor.
Voltage sensing for up to 6S: optimised for 6S packs.
12AWG wiring: low resistance current flow.
Stable measurement: noise-free current readings.
Pixhawk compatible: DF-13 6-pin interface.
A current and voltage sensor board sits in the main battery line, between the battery and the rest of the aircraft. A Hall-effect sensor measures the current without adding a large resistor to the path, and a voltage divider scales the battery voltage down to a level the flight controller can read. The board then sends both values to the flight controller as analogue signals, which it uses for battery-level warnings, failsafe decisions and flight logs.
The sensor board itself does not power the flight controller. It needs a separate regulator (a BEC) that supplies the flight controller, GPS and telemetry modules. Choose a BEC whose input range matches your battery, and connect the sensor's signal cable to the power-monitor port of the flight controller.
For accurate readings, set the voltage divider and amps-per-volt values in the flight controller's battery monitor to match the board, and check the reported voltage and current against a multimeter and a known load. A wrong scale factor can make a battery look fuller than it is. Solder the heavy-gauge wires carefully and protect the joints with heat-shrink.
