LPRS has introduced the eRA-Arduino-S900. A ‘shield’ or stacked module that allows Arduino boards to communicate wirelessly with other eRA module-equipped Arduino boards or PC hosts, using proprietary easyRadio technology operating in the 868MHz to 915MHz ISM band.

Host Arduino boards can now easily send and receive up to 180 Bytes of half-duplex data per packet, seamlessly delivered to all other hosts within range. There is no need for any complicated ‘bit balancing’ or elaborate coding schemes. Addressing and implementation of wireless networking (point-to-point and peer-to-peer) can be handled by Arduino application software proving providing flexibility without sacrificing simplicity of operation.
The LPRS eRA-Arduino-S900 provides considerably greater range (typically 200m) and consumes less power than similar WiFi or Bluetooth devices operating in the overcrowded 2.4GHz bands. Frequency, bandwidth, power output and data rate can optionally be configured to allow multiple devices to communicate free from interference from each other and any other RF devices.
