# Electrical Connection

Power and communication connections are made through Cat5 cable following the T568-B color convention. Internal to the device, the cable is terminated and makes connection to the PCB using JST GH connectors.

Provided external connections are a 4-pin JST GH for connection to a Blue Robotics Ethernet Switch or RJ45 adapter, and spade connectors for connecting to power (10-30 Volts DC).
