With some development boards, low power usage is an afterthought. Especially when price and usability is the main selling point. So what should you do when it's time to turn around and make that project of yours run on a battery or solar? Sure you could...

This OLED display has a wide display area for the times you need to read longer data on a screen. It is easy to connect with I²C and only uses two data wires! There is a great tutorial on Adafruit Learn, follow the instructions for the 128x32 I2C...

The SparkFun QwiicBus EndPoint is the fastest and easiest way to extend the range of your I2C communication bus. The breakout uses NXP’s PCA9615 IC, which converts the two default I2C signals into four differential signals, two for SCL and two for...

Features This Rotary Encoder Modules does NOT Include a knob cap The rotary 6mm shaft provides a large range of compatible knobs to choose from allowing you to get the right knob for your job 3.3 and 5V compatible Compatible with...

Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer?  Sure you can program an Arduino or Trinket to talk to these devices and your...

This DC-DC 12V to 3.3V 5V 12V Power Module Multi Output Voltage Conversion is also known as Buck Converter or also as Step-Down Voltage Converter. The module is capable of altering the output of the power source/supply before...

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 reasonable 42% when it feels more like 77%. Enter...

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 without an analog input. This breakout board has the...

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 GPIO expanders, ADCs, PWM drivers, etc, seesaw can be...

"You see, wire telegraph is a kind of a very, very long cat.  You pull his tail in New York and his head is meowing in Los Angeles.  Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there...

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...

Caution! The BBC micro:bit is NOT included. You can buy the BBC micro:bit here. Looking to do more with your BBC micro:bit? Unlock its potential with this pre-built version of Kitronik Edge Connector Breakout Board! This breakout board has...

The IS31FL3731 will let you get back to that classic LED matrix look, with a nice upgrade! This I2C LED driver chip has the ability to PWM each individual LED in a 16x9 grid so you can have beautiful LED lighting effects, without a lot of pin...
