Wireless Arduino Shield provides 200 m range.
Press Release Summary:
With eRA-Arduino-S900 shield, Arduino boards can communication wirelessly with other eRA module-equipped Arduino boards or PC hosts, using proprietary easyRadio technology operating in 915 MHz ISM band. Host Arduino boards can send and receive up to 180 bytes of half-duplex data per packet, seamlessly delivered to all other hosts within range. Measuring 2.7 x 2.0 x 0.4 in., shield is powered by host Arduino’s 5 V, consuming 25/35 mA in idle/transmit.
Original Press Release:
Saelig Debuts New Low-cost Wireless Arduino Shield
Pittsford, NY, USA:Â Saelig Company, Inc. 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 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.Â
The 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.
The eRA-Arduino-S900 incorporates an eRA900TRS wireless module which provides simple-to-use, out-of-the-box wireless serial communication as a COMport. No complex RF protocol software is required to create an instant bidirectional link. The 2.7” x 2.0” x 0.4” 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 RSSI (Received Signal Strength Indication) – no need for the 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.
• User-configurable self-coding system for interfacing to other data modules in FSK (FM) and ASK (AM).
Made by European short-range radio specialists Low Power Radio Solutions (LPRS), the eRA-ARDUINO-S900 Wireless Arduino Shield is available now from stock from Saelig Company Inc. Pittsford, NY.Â
