Voltage Monitor
The Avionics Anonymous Voltage Monitor is a small 8-channel analog input unit. It allows measurement of analog sensors or monitoring of multiple batteries, voltage regulators, solar cells, etc - any 8 voltage sources that share a common ground. Connects to Pixhawk and other similar autopilots via UAVCAN. Comes fully assembled, ready to use!
Note: This device currently requires custom development to integrate with most autopilot software. Please contact us if you need assistance.
8 separate voltage inputs (common ground)
Inputs are protected against under- and over-voltage
Units are built to order with your preferred voltage range for each channel
Publishes 8x standard UAVCAN "CircuitStatus" messages
Robust UAVCAN interface is compatible with most Pixhawks and similar autopilots
Update firmware via CAN interface
Note: Because the inputs share a common ground, this unit cannot be used to monitor series cell voltages in a battery.
Weight: x.x grams
Size: 1.15in x 1.35in x 0.25in
Input Power: 4.0V to 5.5V, XXmA
​CAN Harness - connects between the autopilot and a CAN node and between each CAN node on the bus
​CAN Terminator - connects to the last device on the CAN bus

The Voltage Monitor is connected to your autopilot via CAN bus. The wiring is per the pinout below, or the necessary cables can be purchased to connect to your system right out of the box:
​CAN Harness - connects between the autopilot and a CAN node and between each CAN node on the bus
​CAN Terminator - connects to the last device on the CAN bus
Analog inputs are connected to channels 1-8 on the 8x2 header. The 8 ground pins, closest to the edge of the board, are tied to a common ground.
