A little roll of thermal paper! This fits very nicely into Nano Thermal Receipt Printer. It's ~2.25" wide (about 57mm) and 16 feet long or about 5 meters. Technical Details: Interior Diameter: 7.8mm / 0.3" Exterior Diameter: 20.6mm / 0.8"

Listen to this good news - we now have a breakout board for a super tiny I2S MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they're way smaller and thinner. This...

Add a really really small printer to any microcontroller project with this very cute thermal printer. Thermal printers are also known as receipt printers, they're what you get when you go to the ATM or grocery store. Now you can embed a...

A little roll of thermal paper! This fits very nicely into our Tiny Thermal Receipt Printer. It's ~2.25" wide (about 57mm) and 33 feet long or about 10 meters. Technical Details: Interior Diameter: 12.6mm / 0.5" Exterior Diameter: 29.6mm...

VL53L0X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL53L0X can detect the "time of flight", or how long the light has taken to bounce...

1Sheeld+ is a "Bluetooth LE Tethered" shield for Arduino. Plug it into your Arduino and then run the matching mobile app on your tablet or phone. Once paired, the mobile app that allows the usage of all your smartphones' capabilities...

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

A button is a button, and an LED is a LED, but this LED illuminated button is a lovely combination of both! It's a medium sized button, large enough to press easily but not too big that it gets in the way of your project panel. It has a...

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,...

Remember those cereal commercials that would always say, "part of a complete breakfast"? Well the Pi Zero's a lot like that bowl of cereal - while it's great on its own, you need a lot of accessories to make it a complete meal. The Pi...

Is this not the cutest, little display for the Raspberry Pi? It features a 3.5" display with 480x320 16-bit color pixels and a resistive touch overlay just like Adafruit's popular original, but this one is engineered specifically to work...

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...
