CanAirIO M5Stack devices support

Overview

CanAirIO M5Stack contains special support for these kind of boards and devices. We this development we are trying to improve an easy way on the building of mobile and fixed stations for CanAirIO Air Quality network.

Advantages

CanAirIO M5Stack devices

Plus the current features of CanAirIO firmware, the M5StickC Plus has the next extra features:

  • Dual I2C port (Hat and M5 grove port). You can connect multiple sensors. For example one EnvII hat and three sensors via grove port plus grove hub
  • Compatibility with internal I2C devices, for example in the M5CoreInk and M5StickC Plus, the internal I2C handled the real time clock and the power unit, the CanAirIO Sensors Library works without conflicts swapping this channel with the hat channel for reach three I2C channels at the same time.
  • M5Stack has a wonderful feature, 5V output, it reduce the complexity of the DIY creation, because we need 5V for example for particulate meter sensors and old UART devices. In comparasion for example to CanAirIO Bike, it is a improvement on the build work.
  • Enclosures and expansion ports. Like we mentioned, M5 has for example DIY box or expansion ports for reduce the complexity in the wiring and the connection.

Firmware upload

We already have a super easy way for install CanAirIO firmware on any compatible ESP32 board like a M5Stack boards in a few seconds. A little video demostration:

canairio_m5stickcplus

More info in canair.io/installer. Other alternatives for upload the CanAirIO firmware, here.

CanAirIO Sensors Lib only

The next some another M5Stack devices that only have the integration with our sensors library.

M5CoreInk

M5CoreInk Basic Air Quality station

This a basic air quality station with the possibility to have many sensors. The full source code and documentation here

M5Atom Lite

In the CanAirIO Sensors lib also is supported this core. Please see the example of the library here. We are close to have a complete CanAirIO firmware release for this core.
