The RedBear Duo is a thumb-size development board made to simplify the building process of Internet of Things (IoT) products. Everything you need is built into the Duo. It contains WiFi, BLE and Cloud, all in a compact form factor that makes it ideal for your first prototype, a finished product, and everything in between.
The Duo is perfect for applications where you want to leverage BLE for low-power local communications with other BLE sensors and devices with the flexibility of waking up Wi-Fi to send data and communications back to the Cloud on a regular interval.
