Communications

Operates at 433MHz. Not a full shield format, but designed to plug into some of the Arduino headers. Provided as a kit including the board, radio receiver, antenna, wire, and headers.

WiFi/WLAN Shield. Features: IEEE 802.11b/g/n/i 2.4GHz Wireless security: AES, WEP, WPA, WPA2 – PSK Ad-hoc (IBSS) and Infrastructure mode (on Ad-hoc only WEP encryption) Integrated WiFi and IPv4 stack (TCP, UDP) Supports up to 8 sockets at the same time

Evaluation platform for the SM130 RFID module. Includes an XBee header, a PCB trace antenna, and a small prototyping area. This board can also be used as an antenna to the SM130 RFID module.

This shield gives the Arduino CAN-Bus capability for communication with vehicle engine management systems. It uses the Microchip MCP2515 CAN controller with MCP2551 CAN transceiver. CAN connection is via a standard 9-way sub-D for use with OBDII cable. Ideal for automative CAN application. The shield also has a uSD card holder, serial LCD connector and….

Wireless sensor network node with data logging. Native RTC, On board CR2032 battery holder. GPS. XBee wireless networking. Native micro SD card socket. Stackable I2C pin header. Dual voltage (5V/3.3V) I2C hub. User defined button and LED. Unusually, this shield can be used either as a regular shield to another Arduino, or standalone using an….

The GPRS (General Packet Radio Service) Shield provides GSM/GPRS 850/900/1800/1900MHz communications for voice, SMS, data, and fax. It is controlled via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands). The GPRS Shield has 12 GPIOs 2 PWMs and 1 ADC(They are all 2V8 logic). Features: Quad-Band 850/ 900/ 1800/ 1900 MHz GPRS multi-slot….

Holds 2 xBee or compatible modules, has a 3.3V regulator, small prototyping area and reset buttons for both the Arduino and one for each xBee footprint. Switch to change the connection of the xBee socket to the serial pins to “cross over” to allow the xBee to be programmed via the FTDI from the host….

Simple GSM / GPRS shield. Features: QuadBand: 850/ 900/ 1800/ 1900 MHz GPRS multi-slot class 10/8 GPRS mobile station class B Compliant with GSM phase 2/2+: Class 4 (2 W @850/ 900 MHz) Class 1 (1 W @ 1800/1900 MHz)

The LinkSprite WiFi Shield has built-in TCP/IP stack and all the WiFi related code. The Arduino just configures the WiFi parameters using AT command through the UART, or the user can simply treat the WiFi as a transparent serial port after some offline configuration.

Adds an RS485 port.
