The Mauch PL-050 current and voltage sensor board gives precise power monitoring for your drone. It can handle up to 50A and accurately measures battery voltage and current for reliable telemetry.
It is encased in a durable CFK (carbon fibre composite) enclosure with pre-wired 12AWG cables, which the listing says makes it ideal for smaller to medium-sized UAVs.
The listing describes a compact, lightweight design that is robust and resistant to EMI, and that supplies vital telemetry data to the autopilot and is essential for battery management and flight time.
High-accuracy sensing: current and voltage measurement.
50A continuous current: for small to medium UAVs.
Up to 14S: maximum voltage input of 60V.
CFK enclosure: durable carbon fibre composite housing.
Pre-wired 12AWG silicone wires: 2 x 10cm, pre-attached.
EMI resistance: robust in electrically noisy aircraft.
Compact and light: 17g without and 22g with the enclosure.
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.
