CAN BUS Interface
OpenTracker features a standard CAN Bus interface on the main connector. The CAN bus needs a
termination resistor (typical 120 Ohm) which is not onboard and will have to be set by the user.
We are using the Ti SN65HVD230 CAN Transceiver. For more info and electrical specifications refer
to the Component datasheets at: http://www.ti.com/product/sn65hvd230
Using CAN
We provide example code in our github repository at https://github.com/geolink/opentracker.
