Solenoids are basically electromagnets: they are made of a big coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull from one end. This solenoid in particular is nice and strong and has a slug with a slanted cut and a good mounting bracket. It's basically an electronic lock, designed for a basic cabinet or safe or...

Alright, maybe we're exaggerating, but these chainable NeoPixel LEDs are not only super-smart, they are also ridonkulously bright with 4W total, 1 Watt per channel, compared to 0.2W of a 'standard' NeoPixel. Each order comes with one RGBW NeoPixel LED...

Solenoids are basically electromagnets: they are made of a big coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull from one end. This solenoid in particular is nice and strong and has a slug with a slanted cut and a good mounting bracket. It's basically an electronic lock, designed for a basic cabinet or safe or...

The datasheet for the DS3231 explains that this part is an "Extremely Accurate I²C-Integrated RTC/TCXO/Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low-power package. We've had a breakout board version of this RTC for a while, but we want to make it even easier for folks to use, so now it comes with STEMMA QT connectors for plug-and-play...

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for data-logging, clock-building, time stamping, timers, and alarms, etc. Equipped with  PCF8523  RTC - it can run from 3.3V or 5V power & logic! We've had a breakout board version of this RTC for a while, but we want to make it even easier for folks to...

The Seeeduino XIAO Expansion Board is a great add-on board with a little-bit-of-everything. It works wonderfully with our QT Py boards so we're stocking it for folks to plug in their SAMD21 QT Py or RP2040 QT Py. It enables prototyping in an easy and quick way and with so many hardware add-ons, you can quickly explore near-infinite possibilities of Arduino and CircuitPython with your QT Py friends. Please note that since QT Py's...

Dress up your Adafruit Macropad with PaintYourDragon's fabulous decorative silkscreen enclosure and hardware kit. You get the two custom PCBs that are cut to act as a protective bottom plate and and a mechanically-stabilizing keyboard plate. Use the included M3 screws to attach the bottom plate - it's symmetric so you can decide which side you'd like to have visible. Stick the rubber feet on the bottom to protect your desk from...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The Adafruit MCP9601 I2C Thermocouple Breakout (a.k.a MCP96L01) does all that for you and can be easily interfaced with any microcontroller or single-board computer with I2C. Inside, the chip handles all the analog stuff for you, and can interface with just about any thermocouple type: K, J, T, N, S, E, B, and R types are all supported! You can also...

When we saw the classic "Zener ESP Card" designed keyboard in the awesome CHVRCHES video for the song "How Not To Drown" (ft Robert Smith!) we were smitten. So goth! So esoteric! So we got a small number of these etched-through keycaps with the 5 designs: circle, cross, waves, square, and star. You don't  have  to wear excessive eyeliner to snap these into your mechanical keyboard... but, hey,...
