In stock
Matek’s CAN-L4-BMย is an ultra-precise digital power monitor based on TI INA239 firmware and ArduPilot AP_Periph.ย It features a low-power resistant path of 200ฮผฮฉ, 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 donโt need it.
- If the CAN wires are too long, bridge the โ120Rโ jumper.
