Atom Lite, which has a size of only 24*24mm, is a very compact development board in the M5Stack development kit series. It provides more GPIOs for user customization which is very suitable for embedded smart home devices and in making smart toys. The main control adopts the ESP32-PICO chip which comes integrated with Wi-Fi and Bluetooth technologies and has a 4MB of integrated SPI flash memory. Atom Lite board provides an Infra-Red LED, a RGB LED, buttons, and a YH2.0 interface. In addition, it can connect to external sensors and actuators through 6 GPIOs. The on-board Type-C USB interface enables rapid program upload and execution.

The shipment arrived very quick, and was very pleased with the packaging and the small form factor. Utilized ESP32 BLE for a small project that required mouse simulation, that also took advantage of the switch and the RGB LED.
It was a quick and convenient solution. Thanks for all of you at M5Stack!
ATOM Lite ESP32 IoT Development Kit
Great for many IOT sensor projects. I am using them with esphome and home assistant with various sensors and they work great!
Awesome little device! I also tried their UIFlow cloud IDE (blockly and python) and it's pretty slick. Nice job M5Stack team!
Exactly as described, works very well, can only recommend this product, good value for money, happy with the purchase
