WIO-02
| Developer page: Do not translate. WIP |
Introduction
The WIO-02 is almost the same as the WIO-01, but is based on the ESP32 (LOLIN D32) instead of the ESP8266 (LOLIN D1 mini).
It has a few extra features:
- CAN connection with Internal Controller and MCP2561.
- Buffered, P82B715, I2C connection compatible with the PiXX serie.
- Sound DAC connection.
- Up to 8 Servos.
- Able to act as CAN decoder.
CAN
The CAN can be used in combination with WiFi to make a bridge between CBUS/MBUS and Rocrail.
If the CAN_IO option is set in the USERCFG.h, WIO-02 will also process commands from CAN/CBUS an report on CAN/CBUS.
Addressing CBUS
Simple I/O, long event type, can be processed if the object has set the Bus value to the target WIO ID.
For controlling servos, LEDs and signal, the object must be set to none accessory, and all other parameters are the same as with WIO addressing.

I2C
Additional RocNet PiXX units can be connected to extend I/O.
