ATOM Lite ESP32 Development Kit

A smart, ESP32-PICO based development kit with built in WiFi and Bluetooth, an indicator LED and a button - brilliant for Internet of Things projects!

These little guys have become firm favourites for our IoT projects, as they're great value, easy to mount places and come with their own built in housing, so you don't need to make an enclosure to protect them. There's a handy pinout diagram on the back of the case, and they work really nicely with Home Assistant and ESPHome if you want to quickly and easily set up a network of sensors.

Because they're so tiny (24mm x 24mm), they'd be also be ideal for incorporating into embeddable or wearable projects where space is at a premium. If you'd like moar lights we also sell an ATOM with an inbuilt LED matrix, and we also stock a compatible plug and play battery!
