Ardupilot firmware

CAN PMU se/CAN PMU Lite

The X7 series flight controller package contains the CAN PMU se/CAN PMU Lite power module. When the flight controller is running Ardupilot, you only need to connect it to Power C, You don’t need to set up a power monitor.

If you set it incorrectly, please modify'BATT_MONITOR' to 8, write the parameters and restart the flight controller.

HV PM Analog current meter

In any case, in the X7 series flight controllers, we do not recommend using an analog ammeter; if you use an analog ammeter, please connect the ammeter to Power A, then set'BATT_MONITOR' to 4, write parameters and restart.

The X7 series flight controllers have the voltage and current detection pins set by default. If you set the ammeter incorrectly, please modify the following parameters:

BATT_MONITOR=4
BATT_VOLT_MULT=18
BATT_V0LT_PIN=16
BATT_CURR_PIN=17
BATT_AMP_PERVLT=24

HV PM/Analog Power Monitor

In any case, in the X7 series flight controllers, we do not recommend using an analog ammeter; if you use an analog ammeter, please set as follows:

Fill in the number of batteries
Single cell full voltage (generally lithium battery is set to 4.0~4.2v)
Single cell empty voltage (generally lithium battery is set to 3.5V)
The voltage divider ratio is filled in according to the data provided by the manufacturer {18(HV_PM)}
Fill in the current-voltage ratio according to the data provided by the manufacturer (24 (HV_PM)
