Description

Matek’s CAN-L4-BM is an ultra-precise digital power monitor based on TI INA239 firmware and ArduPilot AP_Periph. It features a low-power resistant path of 200μΩ, providing high efficiency in power consumption. No calibration is required and DroneCAN protocol offers convenient current & bus voltage readouts.

Any flight controller that supports the DroneCAN protocol will be able to easily get accurate current and voltage readings via CAN.

Tips

The big pad on the bottom side is a dead pad. No any circuit network on it.
Solder the positive wires as close as possible to both sides of the current sensing resistor.
2 ears for mounting can be cut off if you don’t need it.
If the CAN wires are too long, bridge the “120R” jumper.

Included

1x Matek AP_Periph CAN-L4-BM Digital Power Monitor
1x JST-GH-4P to JST-GH-4P 20cm silicon wire
