M5Atom : The smallest ESP32 based development plateform from M5Stack

M5Stack Atom Lite is a very compact development board of 24x 24mm. Even with its small size, the Atom still features GPIOs for user customization. It is a nice plateform to create smart home devices or smart toys.

The Atom is propeled by an ESP32-PICO chip also offering Wi-Fi and Bluetooth capabilities. The ESP32 is wired to a 4MB of integrated SPI Flash memory used to stored the user software.

The Atom provides an InfraRed LED, a RGB LED, buttons and a Grove interface (HY2.0). Thanks to the 6 GPIOs still available, the Atom can be connected to external sensors, actuators and other devices.

The on-board Type-C USB port is used to upload user program to the Atom.
