For those of us who are pre canbus era, I have ruined my leaf adapater board tring to solder extra wires directly to it .

Just a idea would this tiny board work with the V3 board connected to the can bus,

could wire directly to the board, inputs and outputs

It was orignal made for motor sport, fits in the middle of the steering wheel so you connect pots, switches, LEDs.

quick overview:

CAN BUS 2.0B
500 or 1000kbps, user selectable
different CAN ID and CAN frame structures can be selected,
only 25x25mm in size,
8 switch inputs (switched to ground)
8 analog inputs / rotary switch inputs, 0-5V, 10bits
4 low side outputs (0.5A, resistive and inductive loads)
6-22V power supply
+5V output for powering rotary switches, sensors and potentiometers

do you think this could work ??

I'm not familiar with those Ecumaster products and they show no screenshots of their configuration software.

It will probably work fine, especially as even if you can't configure that board, the huebner software can be configured to accept whatever that board is sending by default.

Nice find indeed. I wonder if there is some Chinese $1 version of this

I was just looking at your wiki, im not familiar with can bus, On Johu wiki says the format is Little-endian the ecomaster says it is using Big endian will this be a cross talk issue

Endianess becomes a problem for more than 8 bit values. So shouldn't be an issue for digital stuff and with analog inputs you might be able to limit resolution to 8 bits.

This is also a good alternative.

Has lots of free/open software.
Not open source hardware, but you get schematics.

Have used this myself, it just works.
Don't have all pins broken out, that's why I made my own board.
