M5StickC Mini IoT Development Kit with HATs

by M5Stack

An easy to use, open source, modular mini IoT development kit, with sensor and speaker HATs.

Powered by an ESP32 based processor with inbuilt bluetooth and wifi, M5StickC also includes a motion sensor, an IR transmitter, a microphone and a built in lipo battery.

ENV HAT is able to measure temperature, humidity, air pressure and magnetic fields. It connects via I2C so allows you to obtain 4 types of environment data using just 2 pins, making it ideal for environmental data collecting.

SPK HAT is an M5StickC compatible speaker with integrated single channel 3w amplifier.

This kit also comes with a watch strap mount - ideal for making your projects wearable!
