Voltage and current measurements
This device outputs (over CAN) current on the backup battery and output lines. It outputs
voltage of these lines, as well as voltage of up to 6 individual battery cells. It does not
measure total battery current.
Dual output voltages, for flexibility
The 5V line is intended to power flight controllers and other CAN nodes, over the JST-GH 4-pin
DroneCAN connector. It can also power servos, using the MR-30 connection, which accomodates up to 3A.
The second output line can output either 7.4V or 12V, selected by a jumper. Thisline can be used to power
higher-voltage servos, or digital video transmitters, like from DJI and
HDZero. This line supports an additional 3A.
Battery backup
Supports an optional backup battery, using an XT-30 connection. If the primary battery
is disconnected, or runs out of power, the backup immediately takes over, powering electronics and servos.
This allows for motor-out recovery of fixed-wing aircraft, and maintaining a radio link and camera output for
vehicles that run out of main-battery life for any reason.
Plug and play with ArduPilot and PX4
Easy setup; uses standard DroneCAN messages for compatibility with the most popular flight controllers. Includes
a mounting stand.
CAN-FD ready
Supports up to 64-byte frames, and 5Mbps data rates. It's also compatible with classic CAN systems.
CAN allows for simplified wiring, and robust, interference-resistant connections.
The bare PCB is easy to remove and mount; this is useful for compact builds.
Easy configuration
Data broadcast rate and number of channels are customizable, using the AnyLeaf Preflight software that connects with USB,
or through DroneCAN's parameter standard. Preflight is lightweight and easy to use: Download, launch, and plug the device
into your PC's USB port.
Our firmware and preflight software are written in Rust, for maximum reliability.
