eRIC USB Dongle Utilising proprietary LPRS easyRadio technology operating in the 434MHz or 868/915MHz Industrial Scientific & Medical (ISM) bands a pair of eRIC USB dongles can provide a simple wireless bridge between any host devices that support USB serial TM communications such as a PC or Raspberry Pi or BeagleBone Black etc. These devices provide considerably greater range 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 USB Connection Plug & Play operation, appears as a Com port Low current consumption Can be powered directly from USB port Integral SMA Antenna connector Allows use of extension for optimal antenna position FTDI FT232 USB IC Linux & Windows drivers available (see below) Transmit & Receive LEDs Diagnostics 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 Host devices can send and receive (half duplex) up to 250 Bytes of data per packet that will be seamlessly delivered and presented to other hosts within range. There is no need for any complicated bit balancing or elaborate coding schemes.
