Electronic Components

You have some electrons over here, and you want them over there but you don't want the electrons from over there to be able to come over here? That's what a diode is for, these are directional...

These are high quality Single Pole - Double Throw (SPDT) sealed relays. Use them to switch high voltage, and/or high current devices. This relay's coil is rated up to 12V, with a minimum switching...

What's better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display. Matrices like these are 'multiplexed' - so to control all the...

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. This well made anemometer is designed to sit outside and measure wind speed with ease. To use,...

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large, exposed pads...

The long awaited BME680 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing...

This is a highly integrated round-shaped all-in-one capacitive fingerprint sensor module, which is nearly as small as a nail plate. The module is controlled via UART commands, fairly easy to use...

This is a great general purpose-actuator for tiny mechanisms. The FS90 offers positive control over a 120 degree angle. Operating angle controlled by standard servo pulses between 900us and 2100us...

A button is a button, and an LED is a LED, but this LED illuminated button is a lovely combination of both! It's a medium sized button, large enough to press easily but not too big that it gets in...

This thumbstick is an analog joystick - more accurate and sensitive than just 'directional' joysticks - with a 'press in to select' button. Since it's analog (potentiometers), you'll need two...

This straight bar load cell (sometimes called a strain gauge) can translate up to 5kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that...

It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly...

Waveshare 15423 - Raspberry Pi Expansion Board, 8-ch Relays The RPi Relay Board (B) is an expansion board with 8-channel relays for Raspberry Pi. It gives your Pi the ability to control high voltage...

Waveshare 13992 - 1.5inch OLED display Module, 128x128 pixels, 16 gray scale, SPI/I2C interface This is an OLED display module, 1.5inch diagonal, 128x128 pixels, 16 gray scale, with embedded...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you, and can be easily interfaced with any microcontroller, even one...

The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off. This relay can be used to switch low voltage devices such...

Your power supply problems just got SOLVED! This little circuit board may look tiny but inside is a high efficiency DC/DC step-down converter which can output up to 3 Amp at 5V without the need of...

Adafruit seesaw is a near-universal converter framework which allows you to add add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C...

Sew a little sparkle into your wearable project with an Adafruit LED Sequin. These are the kid-sister to the popular Flora NeoPixel, they only show a single color and they don't have digital control,...
