Zeus expansion interface

The Zeus board have a 2 x 12 expansion pin header with 2.54 mm between the pins. This expansion connector is also available on the CAN4VSCP Odessa module and will be available on other modules also in the future.

For power the board supply Vin (9V-28V) and +3.3V and ground. All boards using it should use 3.3V logic signals. It has a SPI or I2C interface, TTL level serial interface, Five analog channels, five I/O lines, Reset and two interrupt inputs.
