Adafruit M5Stick-C Pico Mini IoT Development Board

The ESP-32-based M5Stick-C is a compact, open-source IoT development board, resembling a fun-sized version of the M5Stack. It is packed with features including a Wi-Fi and Bluetooth powered ESP32, USB interface, Li-Poly battery with charging circuitry, and a 0.96" color TFT display. Additional built-in sensors include an IR transmitter, microphone, and MPU6886 sensor, alongside integrated buttons.

Plug Grove sensors into one end or use the 0.1" header sockets on the other for additional sensor and actuator connections. This makes it ideal for creating ultra-small IoT projects or wearable technology. Despite its miniature size, it boasts the capability of an all-in-one development board, perfect for advanced projects with wireless sensing capabilities.

An available kit offers a watch add-on and additional plug-in sensors. As a core device in the M5Stack product series, it's compatible with a wide range of modules and add-ons in this ecosystem, offering immense potential in the evolving IoT landscape. Comprehensive documentation and tutorials are accessible on the M5Stack website for seamless project development.
