Product Specifications
Product Details
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 there is no calibration required. A flight controller that support DroneCAN protocol can easily get accurate current & bus voltage readouts via CAN bus.
