This product is a 3-in-1 cable. By itself, it can act as an extension cord for any 5.5/2.1mm DC power cable. The heavy 22 AWG wires can handle up to 5A. You can also cut it in half to make two barrel cables (one plug and one jack). This will allow...

Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smartphones and tablets, it's fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE UART Friend! The...

Oh so handy, this little LiPo charger is so small and easy to use you can keep it on your desk or mount it easily into any project! Simply plug it via any MicroUSB cable into a USB port and a 3.7V/4.2V lithium polymer or lithium-ion rechargeable battery into the JST plug...

This adorable little board will come in very handy whenever you need a small amount of 5V power. It's the size of a linear regulator, but it's actually a mini-booster! Input 3V on one side, and get 5V at up to 100mA supply on the other. Perfect for use with battery-powered projects with...

Adafruit seesaw is a near-universal converter framework which allows you to add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C GPIO expanders, ADCs, PWM drivers, etc, seesaw can be configured to give a wide range of capabilities. For example, our ATSAMD09 breakout with seesaw gives...

These push to fit adaptors (also known as one-touch pneumatic couplers) are the easiest way to attach PTFE (or Teflon) tubing to your extruder or hotend. The PTFE tubing simply pushes into the blue fitting - and it holds tight no matter what. The tubing cannot be removed by either pulling...

This lovely little display breakout is the best way to add a small, colourful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory...

A Feather board without ambition is a Feather board without FeatherWings! This is the FeatherWing OLED: it adds a 128x32 monochrome OLED plus 3 user buttons to any Feather main board. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board...

A Feather board without ambition is a Feather board without FeatherWings! This is the FeatherWing Proto - a prototyping add-on for all Feather boards. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather board and let the board take flight! This has a duplicate...

Listen to this good news - we 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 amplifier, it's all in one! The SPW2430 is a small, low-cost MEMS mic with...

FRAM, or Ferroelectric Ram, is the coolest new data storage method that all the fashion magazines are talking about. Oh wait, no that's quilted handbags. But FRAM is pretty damn cool too! It's similar to Dynamic random-access memory, only with a ferroelectric layer instead of a dielectric layer. This gives it stable...

Trinket may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation....

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost...

Unlike most of the other temperature sensors we have, this breakout has a really cool IR sensor from TI that can measure the temperature of an object without touching it! The TMP007 is the latest thermopile sensor from TI, and is an update of the TMP006. The internal math engine does...
