Build an LED Moon Phase clock that updates throughout the cycle!

Need those tricky split-rail voltages for your vintage electronics? The Adafruit TPS65131 Split Rail Boost Converter generates both positive and negative voltage rails from a single 3-5V input. This makes it great for mimicking or replacing a transformer-based power supply or something that needs negative bias. We kept the design compact, and it even has adjustable output pots, so you can tune the voltages from about +6~+15VDC and -6~15VDC.

We stock a lot of chips and development boards that are able to do high quality digital I2S out, which makes for great quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real time. However, we don't have a good selection of I2S DAC boards...until now! We really love the sounds coming out of the Adafruit PCM5102 I2S DAC with Line Level Output - it's got clean, excellent-quality, stereo audio and does not need any MCLK or I2C configuration. Literally just pipe some I2S audio in and it ill just work.

This project is built around a Raspberry Pi 5 running Python code inspired by the Macrodata Refinement program in the TV show Severance. A DRV2605L breakout vibrates a small haptic motor as your cursor gets closer to the intimidating numbers on the screen. A Raspberry Pi Touch Display 2 is used for the screen.

If you've ever said to yourself, "Gee, I wish I had eight 12-bit DACs that came in a single package", well I have good news. The Adafruit DAC7578 Breakout is the answer to your wishes! Within its little package, the DAC7578 has eight 12-bit DACs for whatever voltage setting needs you may have, easily controlled over I2C.

'Round these parts we enjoy unusually-shaped displays. And this one certainly fits the description - it's a 1.28 inch diagonal TFT that comes in a round shape and contains a high density 220 PPI, 240x240 pixel RGB display with full-angle viewing. It looks a lot like our 1.54 inch 240x240 square display, but with the edges beveled off.

The Adafruit LPS28 (LPS28DFW) Pressure Sensor is unique in that it can handle a much higher range of pressures: almost every other sensor we've encountered tops out at about 1260 hPa. That means they're totally fine for measuring altitude for most human endeavors, we tend to stay above sea level. However, for some scientific or deep-water uses, 1260 will not cut it! That's why we're happy to stock a sensor that can go down to 4060 hPa - that's as low as -43,000 feet below sea level in air or 40 meters underwater.

The INA228 is an amazing power monitoring chip, with best-of-everything support: up to 85VDC common-mode, high or low side measurements, 20-bit (!) ADC for precision measurements from milliamp to Amp, and I2C interface for easy configuration of alerts, oversampling, gain adjustments and more!

Adafruit's Sparkle Motion board puts easy LED control right at your fingertips. Onboard Infrared control, a microphone for sound reaction, and multiple LED ports make this board perfect for larger scale LED projects.

Turn an IKEA lazy susan into a motorized turntable using the TMC2209 stepper driver, Adafruit KB2040 and CircuitPython.

Adafruit's Sparkle Motion Mini board is a wonderful choice for wearables or light projects on a smaller scale. With WLED preinstalled it's never been easier to get up and running with NeoPixels.

The TMC2209 makes driving steppers easy-breezy and super-silent. All you need is two output pins, no timers, PWM or real-time microcontroller. Set the DIRection pin high or low to set the spin orientation. Then toggle the STEP pin to take one microstep at a time. You can set whether you want to go faster with 1/8 microsteps, or increase the precision to 1/16, 1/32 or 1/64 microsteps per STEP toggle.

Say hello to our new Newxie 1.14 240x135 Color TFT Display Boards. We think it's T-F-Terrific! It's the size of your thumbnail, with glorious 240x135 high res pixel color. This very, very small display is only 1.14 inch diagonal, packed with RGB pixels, for making very small, high-density displays. And this breakout board is designed for compact stacking on a 0.1 inch grid - with a vertical arrangement that mimics old-school nixie tubes.
