This 2.4"/61mm long antenna has 2dBi of gain and 50Ω impedance so it will work fantastically with just about any 850/900/1800/1900/2100 wireless receiver/transmitter such as any Cellular or GSM/GPRS device.Antenna comes with a SMA connector, which is the most common type...

OMG OMG OMG, did you hear? There's a Raspberry Pi called the Model B+ and check it out...more USB ports, more GPIO, better power supply, four mounting holes, less sticky-out SD card! Yep, that's right, the fantastic engineers at Raspberry Pi HQ have blessed us with a new design....

These earbud headphones are the perfect accessory for your FONA - they've been tested to work with our modules - but can be used with any iOS or Android device that uses a TRRS pinout.  The buds themselves are 16mm in diameter with a nice 40" long.  They come with a...

PowerBoost is the perfect power supply for your portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects. Like our popular 5V 1A USB wall...

Push once to turn on, push again to turn off! This clicky switch makes a great power switch or mode toggler. We like this switch because it's breadboard friendly and more fun than a power switch. Can reliably handle up to 500mA and up to 50V. This is a really satisfying switch.

Lithium-ion polymer (also known as 'lipo' or 'lipoly') batteries are thin, light, and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 1200mAh for a total of about 4.5 Wh. If you need a larger battery,

Listen up! This tiny 1" diameter speaker cone is the perfect addition to any small audio project where you need an 8 Ω impedance and will be using 0.5W or less of power. We particularly like this cone as it's very simple and its metal body is extremely lightweight.

This electret capsule microphone is the same one we use in our great microphone amplifier board. It contains a small vibrating element that will output a few millivolts peak-to-peak. You will need an op-amp to amplify the signal, some chips are designed with the amplifier built-in in which...
