We've been looking for a display like this for a long time - it's only 1.5" diagonal but has a high density 220 ppi, 240x240 pixel display with full-angle viewing. It looks a lot like our 1.44" 128x128 display, but has 4x as many pixels and looks great at any angle. We've seen displays of this caliber used in smartwatches and small electronic devices but they've always been MIPI interface. Finally, we found one that is...

Pogo pins are little spring-loaded contacts, very handy for making jigs, or making momentary (but electrically solid) contacts. We use them by the dozen for making programming and testing jigs but they're handy also if say you want to JTAG program a board that you cant solder headers to - just shove these thin contacts into a 0.1" pitch IDC programming cable and press it onto the contacts. These particular pins are (in our opinion)...

Using our Feather Stacking Headers or Feather Female Headers you can connect a...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. So far we've carried the very nice MAX31855 which is an SPI interface thermocouple amplifier. The '855 is great but if you have a lot of thermocouples to measure it isn't terribly easy to use. That's why we are also carrying the new '850 model from Maxim - it's a "1-Wire" thermocouple amp which can have any number of...

This lovely little display breakout is the best way to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! The 1.44" display has 128x128 color pixels. Unlike the low cost "Nokia 6110" and similar LCD displays, which are...

This new Adafruit shield makes it easy to use a 16x2 Character LCD. We really like the Blue & White 16x2 LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another pin to control the backlight for a total of 7 pins. That's almost half of the pins available on a classic Arduino! With this in mind, we wanted to make it easier for people to get these LCD into their...

This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high. You can also solder a wire to the middle pad and create your own capacitive pad if the...

These durable (but affordable!) gearbox motors (also known as 'TT' motors) are an easy, low-cost way to get your projects moving. This is a  TT DC All-Metal Gearbox Motor  with a gear ratio of  1:90 about double of the 'standard' 1:48 ratio. That gives them higher torque but slower rotational speed. Since they're slower they're good for robots where strength is more important than speed. They look a lot...

Your electronics can now see in dazzling color with this lovely color light sensor. We found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The filter means you'll get much truer color than...

The Adafruit Push-button Power Switch is a tidy little design that lets you control a DC power source using an everyday tactile button. The breakout uses a latching analog circuit that is triggered by a push of the button. Press once to turn on, then press again to turn off. The circuit uses a 3A P-FET to connect and disconnect the IN pin to the OUT pin. Works great from 3V to 14VDC and up to 3A (although the FET gets a little toasty at...

This breakout board will solve all your current-monitoring problems. Instead of struggling with a multimeter, you can just use the handy INA169 chip on this breakout to both measure both the DC current draw and have a handy analog output that is with respect to ground. The analog output makes this an ideal breakout for feedback-loop control. Most current-measuring devices such as our current panel meter are only good for low side measuring. That...
