WIO is the abbreviation for Wireless I/O.
The WIO implementation is based on the LOLIN D1 Mini and de LOLIN D32, which both have WiFi on board and can be programmed in the Arduino IDE environment.
WIO is designed for two main tasks:
The general purpose I/O is comparable with the Pi02/GCA50/CANGC2, using WiFi as wireless communication 'bus' instead of wired I2C/LocoNet/CAN, and
is compatible with all known GCA Extension Units.
The main part of the needed I/O settings are defined in Rocrail, which makes a hardware swap al lot easier.
The in Rocrail defined locomotives can be transferred to the throttle(s) by sending the Short IDs. (Up to 256)
The LOLIN D1 Mini has only enough pins for two push buttons: F0 and Shift. It also needs an extra board for battery management.
The General I/O is controlled by the I2C bus. This I2C bus can simultaneous be used for:
Extra options, which needs accurate timing, are mutual exclusive:
The serial options are also mutual exclusive:
For all basic functionality except throttle.
Features all needed connectors for all options.
Specially for Option DCC and Mobile with integrated 3A booster.
A throttle based on LOLIN D1/D32 with display and rotary.
