ECU Master - CAN switchboard V3

A CAN switchboard is a small PCB that allows easy transmission of up to 8 switch states and 8 analog signals over the CAN bus. This makes the CAN switchboard perfect for racing steering wheels or for converting steering column lever signals to CAN bus. Additionally, the switchboard has 4 built-in low-side outputs that can be activated with a CAN bus message. The main purpose of this PCB is to build custom control panels with buttons, rotary switches, and indicators.

The CAN switchboard is designed to work with EMU BLACK and PMU but can also be used with other devices with custom configurable CAN bus inputs.
