Low-cost easyRadio Arduino Shield from LPRS

##IMAGE_1_R##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.

eRA-Arduino-S900 incorporates an eRA900TRS wireless module which provides simple-to-use, out-of-the-box wireless serial communication as a COM port. No complex RF protocol software is required to create an instant bidirectional link. Measuring just 68.5 x 50 x 10mm the eRA-ARDUINO-S900 Wireless Arduino Shield is powered by the host Arduino’s 5V, consuming 25/35mA in idle/transmit. An integral SMA antenna connector allows for use of an off-board antenna. Transmit and Receive LEDs are provided to confirm communication operation.

Other innovative features available on eRA modules include a digital Received Signal Strength Indication, no need for host to handle A/D measurement, temporary channel selection allows host to scan other channels in real time, temperature compensated crystal-controlled synthesizer for frequency accuracy < +/-1kHz over full temperature range, built-in temperature measurement output and user-configurable self-coding system for interfacing to other data modules in FSK (FM) and ASK (AM).
