A splitter board for power distribution and CAN splitting for robotics and remote vehicles/UxVs, allowing a single CAN and power connection to be split to multiple devices, including dedicated 5V regulation for CAN connections.
The JST-GH connectors are compatible with common Ardupilot and PX4 hardware, as per the UAVCAN Micro and Dronecode Autopilot Connector Standards.
Although this PCB was designed specifically for applications like robotics and rovers with CAN bus motors, actuators, and sensors, it can also be used without the CAN connections as a power distribution and 5V regulator board only.
Other 2 wire protocols that support multiple devices, such as i2c, would also be compatible with this board.
Features:
1x power input (XT30-M)
5x power outputs (4x XT30-F, 1x 2.54mm pads)
1x CAN input* (JST-GH)
5x CAN output* (4x JST-GH, 1x 2.54mm pads)
5V 3.5A output (total)
60V (14S) input (only tested up to 25V or 6S)
LED power indicator
30.5mm x 30.5mm M3 mounting holes
optional CAN termination
optional 5V supply to CAN input connection
*the CAN 'input' shares the same connector as the 'outputs', but by default the 5V pin is disconnected. Using the solder bridge on the rear of the PCB, this pin can be reconnected, to enable power to be outputted on that connector. All CAN high and CAN low signals are directly connected between all connectors.
There is an onboard 120Ω termination resistor with a jumper to enable it.
Test full voltage input range (up to 60V or 14S)
Main power testing - 20A continuous?
5V regulator power testing - max continuous?
