Adafruit 2471 - HUZZAH ESP8266 Breakout Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as...

The SparkFun Large Digit Driver is a chainable controller backpack that can be soldered directly to the back of a large 6.5" 7-segment displays. Large numerical displays are a great addition to any project where you want to be able to see information at...

This is an open sourced ISP (In-System Programming) programmer available from http://www.fischl.de/usbasp/.This is provided as an accessory to MicroHOPE due to several reasons. If you want to develop programs that uses the UART of Atmega32, you need to...

These chrome-plated metal buttons are rugged and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2" thick and you can fit these in place, there's even a rubber gasket to keep water out of the enclosure. On the front of...

This rotary encoder is the best of the best, its a high quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs.) We also...

Spring terminal blocks will simplify your wiring and make your project more rugged. Instead of soldering wires to your perf board, solder in these 0.1" pitch terminal blocks. There's a little spring contact so you can pull back on the plastic bit and...

Keep your 5mm LEDs in place with these little plastic LED holders. These are handy for projects using individual LEDs as they look sleek, and your LED won't budge. Slot the LED through the opening and you'll get a nice *snap* into place. Comes as a...

Non-invasive current transformer, use this sensor clip to build your own Personal Energy Monitor . Model: T17－05 Note:Color might change due to different batchs.  

These chrome-plated metal buttons are rugged and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2" thick and you can fit these in place, there's even a rubber gasket to keep water out of the enclosure. On the front of...

An IC (Integrated Circuit) socket allows you to insert and remove chips easily from an assembled kit or project This item contains 3 of the 28 pin 0.6" wide version. Best used with chips that have 28 pins (2x14) and have 0.6" pin spacing. We also have 0...

The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple...

Design a clock, timer or counter into your next project using our pretty 4-digit seven-segment display. These bright crisp displays are good for adding numeric output. Besides the four 7-segments, there are decimal points on each digit and an extra wire...

Make your own USB connections without slicing apart a USB cable and soldering those thin wires inside. These DIY "USB shells" are available in USB A plug, micro B, mini B and USB A socket. Each shell comes with a two-part snap plastic shell and a proper...

If you have a project where you'd like to be able to detach the wiring, this wire will fit the bill. Its a JST 2.5mm 'free hanging' cable assembly that latches strongly. One wire is marked with a white dashed line. You can't plug these in backwards...

Diffused 5mm tri-color LEDs with separate red, green and blue LED chips inside! Nice indicator, and fun to color-swirl. 60 degree viewing angle.  These are Common-Anode type which means you connect one pin to 5V or so and then tie the other three...

This power jack is designed to fit 2.1mm power plugs snugly and securely. Perfect for adding a power connector to your project. We went for the more expensive "thin pin" type which snap into breadboards or perfboards. They will work where "thick pin"...

Add a bunch of high-power outputs to a microcontroller system with chainable shift registers. These chips take a serial input (SPI) of 1 byte (8 bits) and then output those digital bits onto 8 pins. You can chain them together so putting three in a row...

These chrome-plated metal buttons are rugged and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2" thick and you can fit these in place, there's even a rubber gasket to keep water out of the enclosure. On the front of...

Sensor tip is 2" Chip: DS18B20; Voltage: 3.0~5.5V Temperature range: -55'C~+125'C (-67'F~+257'F) Output wires: Red(VCC), Yellow (DATA), Black(GND)

This mini-kit makes it easy to mount a PSP/Xbox-like thumb joystick to your project. The thumbstick is an analog joystick - more accurate and sensitive than just 'directional' joysticks - with a 'press in to select' button. Since it's analog, you'll need...
