"How could something so simple be so useful?" We heard once that in the 4th millennium B.C. some guy asked the person who invented the wheel that question. The person who invented the wheel's answer, we were told, was something like "well it's not actually that simple - it required engineering...

These threaded rod plates can be used to mount a NEMA 17 motor in place, and are an easy way to set up a lead screw or threaded rod driven motion system. For a quick and easy solution you can mount the motor directly to the plate, or if you'd prefer a more solid...

PowerBoost 500C is the perfect power supply for your portable project! With a built-in battery charger circuit, you'll be able to keep your project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V...

These bearings are made of quality chrome steel, which ensures they are durable and long-lasting. They are double shielded (shielded on each side) in order to keep dust and other particulates out. Specifications Material: Chrome steel Inner Diameter: 7mm Outer Diameter: 22mm Width: 7mm

This high-quality PTFE (or "Teflon") tubing has an internal diameter of 4mm - making it a smooth, easy fit for 3mm filament. Filament will slide smoothly and easily through the tubing - ideal for Bowden style extruder setups. Specifications Material: PTFE (Teflon) Colour: White ID: 4mm OD: 6mm Length: 100mm Temperature Range: -180...

Love FLORA but want a bite-sized version? Look no further, GEMMA is a tiny wearable platform board with a lot of might in a 1" diameter package. Powered by an ATtiny85 and programmable with an Arduino IDE over USB, you'll be able to realize any wearable project! We wanted to design a microcontroller board that...

Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very...

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...

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...

We love our RUMBA+ boards! They're great - plenty of stepper drivers, heater/fan channels to spare, and they're built like a tank. Their biggest weakness? Like most other printer control boards, they're 8-bit. Built around the same ATmega2560 that powers RAMPS, there are limits to what they can do and how quickly...

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...

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...

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....

These two Female Stacking Headers alone are, well, lonely. But pair them with any of our Feather boards and you're in business! What do they do? They stack. Put the headers through your Feather and then you can not only plug them into a solderless breadboard, but you could attach circuitry...

These are the smallest NeoPixel breakouts around! Tiny, bright RGB pixels to your project. These little PCBs are only 8mm x 10mm and have two sets of three pads on the back for soldering wires. These ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable...

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 adapter, we tweaked the output to be 5.2V...
