This repository contains Adafruit and user-submitted description models of hardware for use with Adafruit.io.

These hardware description models (HDMs) are similar in concept to IoT "digital twins", virtual representations of physical development boards. They contain everything Adafruit.io needs to know about the device connecting to it.

If you do not see the board you want to use with Adafruit IO on this repository, follow this how-to guide on the Adafruit Learning System for full instructions about adding a board to this repository.

A hardware description model (HDM) describes the contents (information, properties, physical components) of a development board.

Information related to the hardware including the hardware's name, description and unique identifiers.

A boardName MAY ONLY contain lower case ASCII letters, numbers, and the dash character (“-”).

Components are ports such as digital pins or analog pins. These components are defined within the components array.

Each hardware component is defined by adding the following to the .json description file:

The following properties are set by the WipperSnapper web application. You do not need to define these values:

Hardware exposing the I2C bus may add an i2cPorts array to its HDM.

The following HDM snippet defines an I2C interface on port 0 with a SDA GPIO pin of 34 and a SCL GPIO pin of 33.

"i2cPorts": [
    {
        "i2cPortId": "0",
        "SDA": 34,
        "SCL": 33
    }
],

Example hardware descriptions can be found in the boards/ directory.

• The Adafruit IO WipperSnapper Firmware currently supports the following microcontrollers with a WiFi network interface: ESP8266, ESP32, ESP32-S2, ESP32-S3, SAMD51, SAMD21.
