I could be interested in something like that. When driving long trips with the Kia, there’s definitely some values that would be very nice to be able to see all the time, like ideal range, average consumption since trip started, charging status, charging speed in kWh and km/h and more.

> Four touch buttons (as touch-screen too hard to use in a moving vehicle) - Up, Down, Enter, Back/Cancel.
> A WROVER32 (probably 4MB flash to keep costs down, but perhaps 16MB is possible). This has 4MB SPIRAM.
> MicroSD or SD card slot (full speed 4 wire).
> USB for firmware flashing and console access.
> Bluetooth
> Wifi

> Data (async bus)
> CAN (one single CAN bus)
> Expansion via internal GPIO headers
> OVMS firmware
