The Adafruit Constant Current Boost Converter for LEDs makes driving LEDs easy, whether they're in series or parallel - with a chip that can generate up to 40V and 400mA from 3 to 5V input. Unlike most of our booster chips that generate a fixed voltage (like 5V, or 12V) the TPS61169 increases the voltage until a set current is being drawn. That makes it excellent for LEDs that are specified in current not voltage. Perfect for use with our LED nOOds and filaments, where sometimes you need up to 12V or 24V, at 200mA or so.

Use a Feather RP2040 USB host and MCP23017 solenoid driver with CircuitPython to build a fake typewriter

The Adafruit STSPIN220 Stepper Motor Driver Breakout Board makes controlling stepper motors easy-breezy, with a simple GPIO-only interface. All you need is two output pins. Set the DIRection pin high or low to set the spin orientation. Then, toggle the STEP pin to take one step or microstep at a time. By default the board is configured for 1/16 microsteps per toggle. However, if you want to connect the RESET pin and the two mode pins, you can set anywhere from 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 or even 1/256!

Wireless is wonderful, but sometimes you want the strong reliability of a wire. If you want to incorporate an Ethernet port as a great addition to your IoT project, this Wiz5500 Ethernet Breakout will let you add quick and easy wired Internet. Just plug in a standard Ethernet cable, and run the Ethernet Arduino library (or CircuitPython) for cross-platform networking.

The INA23x is an amazing power monitoring chip, with best-of-everything support: up to 85VDC common-mode, high or low side measurements, 16-bit ADC for precision measurements from milliamp to Amp, and I2C interface for easy configuration of alerts, oversampling, gain adjustments and more!

Build and IoT alarm clock using CircuitPython with sound effects, brightness dimming for night time and cute animations like winking eyes.

Now you can quickly integrate the Sensirion SEN6x environmental sensor node into your microcontroller or microcomputer project, with no soldering or fiddly breadboarding - thanks to this here Adafruit SEN6x Adapter Breakout (for SEN66 and friends). We covered the awesome Sensirion SEN66 environmental sensor nodes on EYE ON NPI a while ago; it's an awesome all-in-one air quality sensor, but it has the annoyance that it requires 3V power/logic, and it has a special cable connection.

Build a custom USB HID device that works like a chording keyset using an Adafruit QT Py RP2040 and coded in CircuitPython.

The Adafruit Sparkle Motion Stick is part of our series of "Sparkle Motion" boards, which are our attempt to make the best small WLED-friendly smart LED driving board in the whole world. The USB Stick version of the Sparkle Motion is a simpler version of our full-featured Sparkle Motion. It even fits into a low cost off-the-shelf case for protection. It can be powered via USB Type A for up to 5V 2A input - you can use off-the-shelf USB battery packs for portable operation.

Robot instrument builds are always fun, but the wiring can be cumbersome. However, this robot friend, built around a toy piano xylophone, requires zero soldering. It runs CircuitPython code on a Metro RP2350 with an I2C to 8 Channel Solenoid Driver breakout connected with a STEMMA QT cable.

Build a motorized camera slider that can pan and slide, creating professional looking effects.

We designed the Adafruit I2C to 8 Channel Solenoid Driver featuring an MCP23017 GPIO expander to make using up to eight solenoids easy and solder-free. Power the solenoids with a DC power supply, 3V to 24V DC maximum. Each solenoid has its own pass transistor AO3406 N-Channel MOSFET. A red LED will light up to let you know that the transistor is on.

We really love the sounds coming out of the Adafruit TLV320DAC3100 I2S DAC with Stereo Headphone and Mono Speaker output - it's got clean, excellent-quality, stereo audio that can connect directly to your 16 ohm headphones and/or a 4 ohm - 8 ohm speaker. This makes it excellent for all-in-one audio projects without needing an external amplifier.

Build an internet-connected asteroid tracker. This tracker displays the asteroid name, date, predicted distance from the moon, predicted distance from earth and impact percentage.

When the TPS65131 Split Power Supply breakout was added to the shop I thought one thing: Eurorack! Eurorack synthesizers use +12V and -12V for their power input. This can be tricky to accomplish with the usual DIY tools at our disposal, thus this project: a simple 5V USB to standard 10-pin Eurorack power supply. Perfect for quickly testing a module or using a module outside of a usual rack setup.
