I/O Modules
The General I/O allows to interface your own electronics. It is the perfect tool to implement your own module. A board area allows you to add components (2.54mm/.1″ spacing). The documentation explains you how to access your own peripherals from the central processor (12 digital I/O, 5 analog 8-bit inputs and I2C bus).
