Pi Compatible USB Dongles are available with either an eRA or eRIC module. Utilising LPRS’ proprietary easyRadio technology and operating in the 868MHz (UK & Europe) / 915MHz (US) and 433MHz (Europe, APAC and China) frequency bands, the Pi compatible USB RF Dongles provide a simple wireless bridge between any host devices that support USB serial communications such as a PC, Raspberry Pi™ or BeagleBone Black. Below we have the longer-range narrowband eRA version and the lower-cost eRIC version.
