This Stemma QT breakout makes all that frustration go away - solder in the ANO...

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...

Quantum superposition is a physics concept that light and matter can be both particle and wave at the same time. This amazing phenomenon can be demonstrated at home when you try to plug in a USB Type A cable in, it's both right-side-up and upside-down at the same time! That's why you have to try at least 3 times to plug it in. The Adafruit Reversible USB Type A Plug...

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...

Rotary encoders are soooo much fun! Twist em this way, then twist them that way. Unlike potentiometers, they go all the way around and often have little detents for tactile feedback. But, if you've ever tried to add encoders to your project you know that they're a real challenge to use: timers, interrupts, debouncing... This Stemma QT breakout makes all that...

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...

We don't quite know what to call this doohicky - some folks refer to it as a USB Condom but that's specifically for when the data lines on a USB port are disabled so that a device charges without data access. This board is a little more advanced: you can manually switch each of the 4 wires on or off for a variety of uses: If you want to have a 'charge only' device,...

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...

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...

We love using chips with 'native USB' peripherals - that's the magic silicon that lets a microcontroller act like an HID keyboard or mouse or disk drive or MIDI synth. It's a standard addition on SAMD21, RP2040, and even the latest ESP32-S2 and ESP32-S3 boards. But what about when you have a classic ATmega328 Uno? or an original ESP32 or ESP8266? Maybe even a...

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...

This is just the PCB for the ANO encoder, the...

Analog switches are a solid state alternative to relays, when you want a smaller, lower-power technology that won't wear out mechanically. And, as the name implies, you can use the Adafruit ADG728 1-to-8 Analog Matrix Switch to connect between eight analog signals, much like a set of 8 mechanical switches. These chips tend to be tiny surface mount parts, so this...

Analog switches are a solid state alternative to relays, when you want a smaller, lower-power technology that won't wear out mechanically.

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...

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...

It's a nifty kit, but the pin-out is a little odd - and there are a ton of pins needed to connect to the rotary encoder and five button switches. This Stemma QT breakout makes all that frustration go away. The onboard...

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...

Do you have any devices with USB C connections that don't seem to power or work when plugged into another USB C port? Chances are, the designers skimped a few pennies or just forgot to put in the two 5.1K CC resistors required for C-to-C connections at 5V. It can drive you batty because some computers care and some don't! That's why we designed the Adafruit USB Type...

Qwiic, or STEMMA QT, is a very efficient way to quickly prototype an idea, but a lot of Qwiic/Stemma QT driver boards only have one port, and devices have two ports but that's only good for chaining. This Multiport board allows boards that have only one Stemma QT/Qwiic port to be added to the I2C bus. Or, use this hub to add as many I2C devices to the bus as you...

When you want a svelte USB C build, a 'sunken' type connector that straddles the PCBA will let you keep your build super slim.
