Ausführliche Informationen und Technische Daten:

  • CAN-L4-BM is a ultra-precise digital power monitor based on TI INA239 & ArudPilot AP_Periph firmware.

  • The resistance of this conductive path is 200 μΩ typical, providing low power loss in the application.

  • With this device, No calibration required, flight controller that support DroneCAN protocol can easily get accurate current & bus voltage readouts via CAN bus.

  • Power supply for CAN-L4-BM board : 4.5~5.5V @5V pad/pin

  • Power consumption: 10mA

  • Operating Temperatures: -40~85 °C

  • Physical

  • Firmware

  • Parameters

    • CAN_P1_DRIVER = 1 if attached to CAN bus1 port or CAN_P2_DRIVER = 1 if attached to CAN bus2 port

    • BATTx_MONITOR = 8 (DroneCAN-BatteryInfo)

Packing

  • 1x CAN-L4-BM board

  • 1x JST-GH-4P to JST-GH-4P 20cm silicon wire

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.
