RedBear DUO - Wi-Fi + BLE IoT Board


The RedBear Duo is a Wi-Fi + Bluetooth Low-Energy (BLE) development kit. The RedBear Duo leverages its Wi-Fi and Bluetooth connections to connect to the Particle Cloud, publish and subscribe to online events, trigger webhooks, and update firmware over the air.

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. Best of all, the RedBear Duo is compatible with all Particle development tools, including our Web IDE, Desktop IDE, and our developer Console.

This board can ship with or without headers. Units with headers are great for using with breadboards; units without headers are best for surface mounting and special applications.
