BLUE bean

Data sheet

BLUE bean is a high performance and ultra low power

surface mount USB radio combining single-stream

11ac Wave2 Wi-Fi and Bluetooth® 5.0 in a very small form factor

BLUE bean is IEEE 802.11b/g/n/a/ac Wave2

dual-band wireless LAN and Bluetooth 5.0 USB

module optimised for small size and low power

consumption.

It is based on Qualcomm QCA9377-7 chipset. Has an

integrated dual-band (2.4 and 5 GHz) 1x1 802.11ac

Wave2 WiFi (supporting MU-MIMO) and Bluetooth®

5.0 transceivers and combined in to very small form

factor (17 x 12 mm with RF connector and 24 x

12mm with integrated antenna).

The radio module supports advanced power saving

techniques. Bluetooth supports both Class1 and

Class2 transmissions and advanced coexistence

mechanisms allow it to work seamlessly with Wi-Fi

ensuring good quality and high performance.

BLUE bean software drivers are available for Linux,

Windows 10 and Android operating systems.
