Battery Monitor Settings¶
The Power_ADC 1 monitor is enabled by default and the Power_ADC 2 monitor parameters are preset, even though it is not enabled by default.. However, if lost or changed:
BATT_MONITOR =4
Then reboot.
BATT_VOLT_MULT 18.0
BATT_AMP_PERVLT 24.0
BATT2_VOLT_MULT 18.0
BATT2_AMP_PERVLT 24.0
DroneCAN PMUs would need to be enabled using a BATTx_MONITOR = “8”.
DroneCAN capability¶
There are 4 CAN ports which allow connecting two independent CAN bus outputs. Each of these can have multiple CAN peripheral devices connected. There are also two separate CAN POWER ports for easy access to CAN-PMUs.
Loading Firmware¶
The board comes pre-installed with an ArduPilot compatible bootloader, allowing the loading of xxxxxx.apj firmware files with any ArduPilot compatible ground station.
Firmware for these boards can be found here in sub-folders labeled “PixPilot-V6PRO”.
