SWCAN module can be most easily acquired from eBay: https://www.ebay.com/itm/365182274464 (seemingly sold by @WaferThinLogic) (installation details to be added later)

Can also be sourced from PCBWay here: https://www.pcbway.com/project/shareproject/SWCAN_adapter_for_OVMS_b002c070.html

However, PCBWay has its own challenges because the files provided do not include a Centroid/Pick-and-Place file. This has led to confusion with the manufacturer and risks components being soldered in incorrectly. It is probably better for most users to procure a prebuilt version online.

SWCAN PCB design appears to have been authored by @kssmll here: https://github.com/kssmll/ovms-swcan-board (Notice the high resolution photos matching the ones on PCBWay)

Please note that OVMS v3 on the Bolt is generally compatible with OBD splitters, allowing other components to also plug into the CAN bus at the same time, such as Bluetooth OBD dongles for use with A Better Route Planner (ABRP).
