Cooling fans...They're everywhere, and they serve the important purpose of keeping things cool, generally electronics. One might rightfully think: "these fans are pretty good at moving air to keep things cool; maybe I can use one of these neat computer fans to keep my widget frosty" followed closely by throwing up one's hands in confusion at the sight of a 3 or even...

Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer? Sure you can program an Arduino or Trinket to talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself? Well, now your computer can talk to devices using the Adafruit FT232H breakout...

Throw out all those Mini and Micro B USB cables you have in a plastic bin - the next generation of USB connectors is here with USB C! You will start to see these connectors pop up on all sorts of devices, as the industry moves from micro B or lightening to the new standard. Well, at least until the next standard comes out USB C features a symmetric/reversible...

I2C stands for Inter-Integrated-Circuit communications, it's meant for short distances on a PCB or subassembly. But, hey, we're engineers, and we like to push the limits of technology, right? So why not try to have I2C run over a meter long cable, or even longer? Well, if you try to do that you'll quickly find that the length of the cable adds capacitance and...

This Simple USB Type C breakout is kinda interesting, it looks similar to this USB Type C SMT Inline Breakout Board, but it's an 'inline' style with pads for soldering to the common USB 1.1/2.0 connections. We see this lil breakout used often in custom keyboards, it's glued or wedged into the enclosure. Unlike our breakout, it doesn't break out all the pads - it just...

Character LCDs are a fun and easy way to have your microcontroller project talk back to you. They are also common, and easy to get, available in tons of colors and sizes. We've written tutorials on using character LCDs with an Arduino (or similar microcontroller) but find that the number of pins necessary to control the LCD can be restrictive, especially with...

The ANO rotary encoder wheel is a funky user interface element is reminiscent of the original clicking scroll wheel interface on the first iPods. It's a nifty kit, but the pin-out is a little odd, so we made a handy breakout board that converts the funky pin set into a straightforward, breadboard-friendly header strip. This is just the PCB for the ANO encoder, the...

Take a deep breath in...now slowly breathe out. Mmm isn't it wonderful? All that air around us, which we bring into our lungs, extracts oxygen from and then breathes out carbon dioxide. CO2 is essential for life on this planet we call Earth - we and plants take turns using and emitting CO2 in an elegant symbiosis. But it's important to keep that CO2 balanced - you...

The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed...

This USB Type C breakout is kinda interesting, it looks similar to our right angle USB C socket breakout, but it's an 'inline' style with pads for soldering to the connections. We think it could be handy for making custom cable harnesses! Unlike our breakout, it also has the true dual-row USB C connector and all pads broken out. It does not have any resistors to set...

Sometimes you'll find yourself with an I2C bus controller on one side, and an I2C bus device on the other and you gotta keep em (electrically) separated. Maybe because one is Earth-grounded, maybe because you've got some funky power monitoring setup, maybe you want to reduce noise. Whatever it is, you can use the Adafruit ISO1540 Bidirectional I2C Isolator to add...

You've got secrets, and you want to keep them safe? Most microcontrollers are not designed to protect against snoopers, but a crypto-authentication chip can be used to lock away private keys securely. Once the private key is saved inside, it can't be read out, all you can do is send it challenge-response queries. That means that even if someone gets hold of your...

Have some USB logic analyzer, multimeter or oscilloscope and bumping up against the frustration of a shared earth ground? The Offspring (known for being electrical engineers) wisely sang "Ya gotta keep'em isolated!" Power and signal isolation improves common-mode voltage, enhances noise rejection, and permits two circuits to operate at different voltage levels. This...

As we've been adding STEMMA QT connectors to our breakouts and dev boards, folks have been really enjoying the simplicity and speed of plugging in I2C sensors and devices for quick iteration and design. That's all good, but I2C wasn't really designed for hot-plugging. You're kinda supposed to have everything connected once on boot and never mess with it - I2C was...

You can add in some terminal blocks to make the wiring easier, or check out the HDMI Socket to Terminal Block Breakout which comes with them built in. We recommend this adapter...

Potentiometers are the perfect tool when you want to change your circuit by turning a knob. Turns out, there are times when you want to adjust your circuit without manually turning a knob, and the DS1841 I2C Logarithmic Resistor from Maxim can do just that. It's a programmable resistor, similar to an I2C potentiometer like the DS3502 I2C Potentiometer, so why...

A couple of months ago we started carrying packs of colorful step switches reminiscent of the 16-step sequencer keys on TR-808 synthesizers. We gave folks the heads up that the switches are not breadboard or perf-board friendly i.e. would need to either be hand-wired or designed into a PCB. And then we heard LCD Soundsystem is coming back on tour - so we sold our...
