This shield can play up to 22KHz, 12bit uncompressed audio files of any length. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read from a commonly-available SD/MMC card. Volume can be controlled with the onboard thumbwheel potentiometer. Audio is played asynchronously as an interrupt, so the Arduino can….

This shield is designed to make prototyping on your Arduino easy by giving you space to add your own parts without requiring a custom shield PCB. Reset button up top. ICSP header. Lots of GND and +5V rails. DIP prototyping area makes it easy to add more chips. SOIC prototyping area above USB jack for….

A dual-purpose shield with a 0.1″ grid prototyping area and also extends the Arduino pins to screw terminal blocks. The stackable wing design allows it to fit under other shields and still get easy access to the analog and digital ports of the Arduino. The ScrewShield can be stacked above or below most other shields…..

A useful shield for NFC and RFID communication

Full-featured motor control shield that will be able to power many simple to medium-complexity projects. 2 connections for 5V “hobby” servos connected to the Arduino’s high-resolution dedicated timer. 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 36VDC. Up to….

SD card interface works with FAT16 or FAT32 formatted cards. 3.3v level shifter circuitry prevents damage to your SD card. Real time clock (RTC) keeps the time going even when the Arduino is unplugged. Prototyping area for soldering connectors, circuitry or sensors. Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs….

This shield supports any of four popular GPS modules and stores data on a standard DOS-formatted SD flash memory card. Simply plug it into your computer when you’ve finished your data capture and the plain text files are ready for importing into Google Earth, GPSvisualizer, or a spreadsheet.

This is a shield that provides a lot of flexibility in adding Ethernet/Internet connectivity to Arduino. You can use either an XPort module or a WIZnet module as the “engine”. Both modules have pros and cons, so you can decide which is better for you. One option is you can go with a XPort, XPort….

Touchscreen display shield with microSD card socket with 240×320 pixel resolution 2.8″ diagonal TFT LCD. White LED backlight. 18-bit colour (262,000 different shades). Resistive touchscreen.
