Overview

CanAirIO for M5Stack devices contains special support for these kind of boards and devices. In 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.
