[Ovmsdev] v3.2 hardware schematics and PCB layout

[Mark Webb-Johnson]

These expansion boards under manufacturing as we speak. mPCI-E is unlikely to be feasible for the small embedded ARM processor we use. Can be configured to work as expansion on top of existing modem, or without.

Our modular modem boards are pretty flexible, and we can swap out modems for newer technology, without changing the motherboard.

Regards, Mark.

The only changes are related to EMC, and addition of components to bring that under control (doing it at board level avoids the need to change vehicle cables). We also made minor three component changes to meet ROHS requirements (a micro USB connector, and the red plastic dust caps on the antennas). You can find these documents in the vehicle/hardware/v3.2 directory.

EU kits (with CE conformity) should be available within the next week or two at Fasttech, and shortly after that at shop.openenergymonitor.com <http://shop.openenergymonitor.com/> (for direct distribution within EU).
