Building a custom power setup comes with an increased risk of damaging Skynode. Skynode warranty is voided by the use of any described power setup on this page. This page serves to inform the knowledeable system integration engineer.
To enable and configure it, keep the BAT1_SOURCE value at default (Power Module). Set the parameter ADC_ADS1115_EN to 1 and then configure it like a regular . Typically the voltage dividers and amps-per-volt values are given by the power module manufacturer, and the channel mapping depends on your wiring. For example, with a the following settings would be appropriate
BAT1_SOURCE = Power Module (default)
ADC_ADS1115_EN = 1
reboot (and restart AMC)
BAT1_I_CHANNEL = 1
BAT1_V_CHANNEL = 0
BAT1_V_DIV = 18.182
BAT1_A_PER_V = 36.364
BAT1_N_CELLS = 6
The CAN PMU connector has 6 pins:
(Red cable) - 5V
(Red cable) - 5V
(Yellow cable) - CAN P
(Blue cable) - CAN N
(Black cable) - GND
(Black cable) - GND
Pins 1, 2, 5, 6 can be directly connected to pins 1, 2, 5, 6 of J5 or J6 on Skynode:
Once the CAN PMU is connected to Skynode, just set the parameter UAVCAN_ENABLE to 2 (Sensors Automatic Config) and reboot.\
Custom power cables from the CAN PMU connector to J5 or J6 on Skynode could introduce voltage drops. It is highly recommended to cut the cables and solder the wires together.
The from CUAV is a drone power management module that supports input voltage from 6 to 62V and currents up to 110A. It uses advanced CAN bus communication and supports the standard protocol.
Pins 3 and 4 instead needs to be connected respectively to pins 2 and 3 of J14 (CAN1) on the :
This page describes how to power Skynode in a system where the Auterion Power module is not an option.
