RF Link Transmissor - 434MHz

4 Bits Digital LED Display

These wireless receivers work with our 434MHz transmitters. They can easily fit on a breadboard and work well with microcontrollers to create a very simple wireless data connection. Since these are just the receivers, they will only work one way data communication, you would need two pairs to act as a transmitter / receiver pair.

2.4 GHz 3dBi foldable antenna with reverse bias - SMA RF connector. Perfect for prototyping with RF ICs and Xbee modules. 50 ohm impedance. 10.16cm in length.

infrared devices are widely used and often for remotely controlled devices . With this IR receiver, your Arduino project is now able to receive commands from any IR remote controller.

This is an os card for our RFID readers . The SparkFun L eid RFID Breakout converts the 2mm pins to the breadboard in a friendly 0.1 "headers. With this ability the ID-3LA, ID-12LA, and ID-20LA you can weld the reader directly to the header or use the 2 mm connectors

The Arduino WTV020-SD MP3 Module is a voice recording module with 1GB SD Card storage capacity. You can upload WAV and AD4 format files that conform to FAT formatting. It supports 6KHz to 32KHz, being 36KHz for AD4 files and 6-16KHz for voice sampling rate (Audio Sampling).

The Module KA2284 is a Battery, Power and Audio Level Indicator.

You can fix it to the wall using screws or double sided tape. Have Command tidy and always at hand with this Simple Support.

The NRF24L01+ Module is an excellent wireless communication option between devices like the Arduino.
