Modulo-2 is a Wi-Fi and Bluetooth® low energy development board that makes it easy to prototype and build connected products used in conjunction with the Afero IoT Platform. It enables ultra-low power connectivity for data communication. The product integrates a Wi-Fi/Bluetooth® radio, RF front-end, a microcontroller running the Afero custom firmware, security IC, and crystal into a small package. This is an ideal solution for Internet of Things (IoT) applications.
