eRIC9-DUINO LPRS

eRIC Shield for Arduino This shield allows Arduino boards to communicate wirelessly using proprietary LPRS easyRadio technology operating in the 433MHz or 868/915MHz (Industrial Scientific & Medical (ISM) bands. The essence of these devices is easy. Host Arduino boards can send and receive (half duplex) up to 250 Bytes of data per packet that will be seamlessly delivered and presented to all other hosts within range. There is no need for any complicated bit balancing or elaborate coding schemes. Easy: Data In and Data Out These devices provide considerably greater range (typically 200m) and less power consumption than similar WiFi or Bluetooth dongles 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. Features Benefits LPRS easyRadio RF Transceiver technology Bi-directional link, no RF protocol software required Transmit, Receive, Busy and Power LEDs Diagnostics Integral SMA Antenna connector Allows use of extension cable for optimal antenna position in product Configurable RF parameters (optional) Fine tune for optimum performance Up to 250 Bytes per packet Ideal for Sense & Control applications Built-in Temperature Sensor Usable by host program Addressing and implementation of networking (point to point, peer to peer, mesh) can handled by Arduino application software thus providing flexibility and simplicity. An optional on-board 4 pin header allows connection of an external FT232 USB adapter device to configure the easyRadio module should need be. eRIC Arduino 1.0.docx Page 1 of 3 D0 eRIC Rx D2 D1 eRIC Tx D3 D0 eRIC Rx D2 D1 eRIC Tx D3 eRIC Shield for Arduino Specifications Supply: +5V 5%, Temperature 20C Parameter Min Typical Max Units Notes /Default Supply Voltage 5V Volts Powered by host Arduino Supply Current 25 mA Receive (Idle state) 35 mA Transmit Data Rate 2.4 19.2 115.2 Kbps Configurable - See Note 1 below Packet Size 1 250 Bytes Auto detect end of packet Frequency (Default) 434 MHz Configurable 868 MHz Version 915 MHz Version Receive Sensitivity -107 -117 dBm Configurable RF Output Power -5 +9 +10 dBm Configurable Antenna 50 Via SMA Connector Range 200 m Dependant on conditions/terrain Operating Temperature -40 20 85 C Mechanical Size 68 x 52 x 10 mm Excluding connectors & antenna Weight 24 g Without antenna Notes 1) Parameters can be configured using easyRadio Companion software available from: www.lprs.co.uk 2) Please read this datasheet in conjunction with the easyRadio eRIC datasheet available from: www.lprs.co.uk 3) The board is supplied with either an eRIC4 or eRIC9 module fitted together with a matching 434MHz or 868/915 MHz antenna. Jumper Pin Configuration Hardware Serial: Software Serial: Connects eRIC to Arduino Connects eRIC to Arduino hardware serial port (UART) software serial port on D2 on D0 and D1 and D3 Other Serial: Alternatively remove the shorting jumpers and use male to female jumper wires. Connect the female ends of jumper wires to eRIC Rx and Tx pins and connect the male end to corresponding/preferred serial-enabled pins on Arduino. eRIC Arduino 1.0.docx Page 2 of 3
