One of each of our favorite 13.56MHz RFID/NFC Classic 1K tags - 5 in total! Credit card size 1" diameter 'laundry' clear tag 1" diameter 'laundry' white tag Key fob Sticker These can be read by almost any 13.56MHz RFID/NFC reader but...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time Adafruit have MAX31855K breakout, which works great but is only for...

Your microcontroller probably has an ADC (analog -> digital converter) but does it have a DAC (digital -> analog converter)??? Now it can! This breakout board features the easy-to-use MCP4725 12-bit DAC. Control it via I2C and send it...

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over...

Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great...

The Adafruit Feather nRF52 Pro is our latest Bluetooth Low Energy board for advanced projects and users who want to use a fully open source Bluetooth Low Energy 5.0 stack . It has a native-bluetooth chip, the nRF52832, as well as built...

With some development boards, low power usage is an afterthought. Especially when price and usability are the main selling points. So what should you do when it's time to turn around and make that project of yours run on a battery or...

Listen to this good news - Adafruit now have a breakout board for a super tiny MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they don't need a bias resistor or...

This 4" / 100mm long flexible uFL 2.4GHz antenna has approx 4DBi gain and a 50Ω impedance so it will work fantastically with just about any 2.4-2.5GHz wireless receiver/transmitter such as the Adafruit CC3000s! Antenna comes with a uFL...

Never hunt around for another crystal again, with the Si5351A clock generator breakout from Adafruit! This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from The...

Electronics and water don't usually mix - which is why liquid level sensing projects can be a little challenging. You can DIY a sensor but keeping it clean and un-oxidized can be a pain. The Optomax Digital liquid level switches are a...

If you own a MacBook, you'll recognize this little friend. The premise of this 2.1mm DC Barrel Jack to 2nd Generation MagSafe Adapter is simple. There's a MagSafe plug on one end and a 5.5mm/2.1mm DC barrel jack with center positive...
