    "description": "**Matek **  **AP_Periph DroneCAN Digital Power Monitor, CAN-L4-BM**\n\n구성\n\nCAN-L4-BM 보드 1개\n\nJST-GH-4P ~ JST-GH-4P 20cm 실리콘 와이어 1개\n\nDue to limitations by AP_Periph firmware, the fw AP_Periph V1.7.0 and older do not support current readings greater than 90A.\n\n**You can update the fw to latest** . then set AP_Periph parameters  **BATT_MAX_AMPS = 204.8 and BATT_SHUNT = 0.0002.**\n\nhttps://github.com/ArduPilot/ardupilot/pull/26465\n\n- CAN-L4-BM is a ultra-precise digital power monitor based on TI INA239 & ArudPilot AP_Periph firmware.\n- The resistance of this conductive path is 200 μΩ typical, providing low power loss in the application.\n- With this device, No calibration required, flight controller that support DroneCAN protocol can easily get accurate current & bus voltage readouts via CAN bus.\n\nSpecifications\n\nMCU: STM32L431xC, 256KB Flash\n\nINA239 85-V, 16-Bit, High-Precision Power monitor IC With SPI Interface\n\nBattery Voltage sense input: 0~85V\n\nCurrent Sense Range:  0~204.8A\n\nLoad current on current sensing resistor:  150A(Continuous),  204.8A(Burst)\n\nVoltage accuracy: ± 0.1%\n\nCurrent accuracy: ± 2%\n\nInterface\n\nCAN, DroneCAN Protocol\n\nUART2, spare, DFU\n\nST debug, SWCLK & SWDIO\n\nLED\n\nBlue, Fast blinking,  Booting\n\nBlue, Slow blinking, working\n\nRed, 3.3V indicator\n\nPower supply for CAN-L4-BM board : 4.5~5.5V  @5V pad/pin\n\nPower consumption: 10mA\n\nOperating Temperatures: -40~85 °C\n\nPhysical\n\nBoard Size: 30mm*22mm*3mm.  4g\n\n3D file : CAN-L4-BM_STEP.zip\n\nFirmware\n\nArduPilot AP_Periph  MatekL431-BattMon\n\nUpdate via DroneCAN GUI Tool\n\nParameters\n\nCAN_P1_DRIVER = 1 if attached to CAN bus1 port or CAN_P2_DRIVER = 1 if attached to CAN bus2 port\n\nBATTx_MONITOR = 8 (DroneCAN-BatteryInfo)\n\nBATTx_OPTIONS = 1\n\nPacking\n\n1x CAN-L4-BM board\n\n1x JST-GH-4P to JST-GH-4P 20cm silicon wire\n\nTips\n\nThe big pad on the bottom side is a dead pad. No any circuit network on it.\n\nSolder the positive wires as close as possible to both sides of the current sensing resistor.\n\n2 ears for mounting can be cut off if you don’t need it.\n\nIf the CAN wires are too long, bridge the “120R” jumper.",
