This is a USB type C to CAN Bus adapter, with a dual DF-13 and 2.54mm header interface for increased flexibility and ease of connection with Tinymovr boards.
It is an evolution of the canable adapter, and it is Open Source.
The adapter comes pre-flashed with the slcan firmware, but you can flash the alternative candlelight firmware. The easiest way to flash is to visit the Canable updater utility using Chrome.
