There are plenty of Arduino-compatible boards you can rely on to build internet of things devices. The Autonomo is quite special though. It is a matchbox sized, Arduino-compatible microcontroller that is powered by a solar panel. You can use it to build autonomous connected devices to get notifications on events that matter to you.
Autonomo has a Grove shield, which means you can connect your Grove sensors and actuators. The board has a modular design, allowing you to choose the communication module that works for your project (including WiFi, GPRS/2G, 3G, LoRa, SigFox and Bluetooth). Like what you see?
