Tiny ESP32 powered dev kit with a built in 5x5 RGB LED matrix, which also functions as a programmable button.  At only 24x24mm, it's great for fitting into projects where space is at a premium!

These little fellas would be super for incorporating into all sorts of projects which would benefit from a smart, wifi connected button that's capable of showing visual feedback. You could set up an IoT thermostat system, use one as as a synth controller, or as a calendar connected busy light/doorbell for your home office.

It's programmable via Arduino IDE, but also by the graphical drag and drop programming interface UIFlow, ideal for folks new to ESP32 microcontrollers. If you don't need the LEDs, we sell the basic ATOM here , and we also stock a compatible plug and play battery!
