WIO Overview

• WIO
• WIOesp32 16 I/O
• WIOpico 16 I/O
• WIOpi
• First steps
• WIO Setup Dialog

WIO is the abbreviation for Wireless I/O.
There are two flavours of WIO:

• WIO which is targeted to the ESP8266, ESP32 and RP2040(PicoW) microcontrollers,
  
• WIOpi for the Raspberry Pi single-board computers.
  

• WIO Flyer (2019)

A target board is required to start with WIO.

• Wemos D1 Mini
• Wemos Lolin D32
• ESP32 D1 Mini
• ESP32 Dev Module
• ESP32 Wrover Module (CAM)
• ESP8266 ESP-01S

• Pico W

• Zero W 1, 2
• RPi 1, 2, 3, 4

The most easiest way to start with WIO is the PicoW from Raspberry Pi.
It does not need any additional software for programming.

• OTA from scratch (OTA=Over The Air)

• WIOpico (Pico W)
• WIOpi (Zero & RPi)

WIO Dialog:

• Easy setup on the Maintenance tab

Tips:

• WIO only support 7 bit ASCII for SSID Name and Password. (Do not use special characters like: äüöß.)
• Multicast must be enabled in the network router to be able to find the Rocrail server automatically.
• The WiFi channel must be in range between 3 and 11. Under certain circumstances it is advisable to use a fixed channel in the AP.
