The Mauch 071 HS-050-LV is a precision 50A current measurement sensor board designed for UAV power monitoring. It is based on the Allegro ACS-50U Hall sensor and provides accurate current and optimised voltage readings for systems up to 6S LiPo.
The listing says it gives reliable flight data for Pixhawk and APM controllers, with high-quality 12AWG wiring for low-resistance current flow and stable, noise-free current measurement.
It is a compact board that needs an external BEC power supply for operation, and it suits professional and hobby UAV applications.
50A current measurement: Hall-effect technology.
Allegro ACS-50U: a reliable current sensor.
Voltage sensing for up to 6S: optimised for 6S packs.
Telemetry data: accurate power data for the flight controller.
Pixhawk 1 and APM: designed for these controllers.
12AWG wiring: low resistance current flow.
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.
