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.
