This GPS antenna draws about 10mA and will give you an additional 28 dB of gain. It's got a 5 meter long cable so it will easily reach wherever you need it to. The antenna is magnetic so it will stick to the top of a car or truck (or any other steel structure).
The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Inside the big USB plug is a USB<->Serial conversion chip and at the end of the 36" cable are four wire - red power, black ground, white RX into USB port, and green TX out of the USB port. The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chipsets.
This is a pre-wired and waterproofed version of the DS18B20 sensor made with a PTFE wire cable.
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 chip itself, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, all assembled and tested.
The Adafruit panel current meter is handy device to have display when you want to monitor or view the current flow situation in a circuit application. This panel meter requires a DC voltage to run, and then has two thick gauge wires to measure current draw. A shunt is already on board so its very easy to hook up!
Build your own ambient-light addition for a monitor or media PC television with the Adalight project pack!. By running the Processing code on your computer, the halo of LEDs will follow the screen colors to provide an awesome ambient light display that adds pop to TV shows, movies or games! Works using open source Processing and Arduino - so it'll run on Mac, Windows or Linux computers!
This is an assortment of the most common sensors used in electronics. 9 sensors and 3 additional components to interface with the 'analog world'.
This kit is for making your own breadboard-friendly very low dropout adjustable power supply. A good power supply is essential to electronic projects. While there are many existing designs for adjustable power supplies, this one makes improvements that make it more useful for hobby designs.
This clock kit is a open source platform for designing clock display and others. MONOCHRON® is a new clock kit from Adafruit! This easy kit is easily hackable to do whatever you wish, it's a clock platform - have fun! 128x64 LCD (KS0108) - we special-ordered the black and white display!
This breakout board has a microSD card slot for providing extra storage memory when required.
This breakout AVR board is a prototype design with minimum components. We took the business-card-sized AVR target board from Evil Mad Scientist Laboratories and added a few components to make an AVR dev board that has only the bare minimums!
This is an in-line wire one to four way splitter, where you can have multiple EL wires connected.
Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz, 12bit uncompressed audio files of any length. It's low cost, available as an easy-to-make kit.
This is a USB Arduino compatiable kit with an ATmega328 chip. This development board acts just like an Arduino, and works with the latest Arduino software.Â
This is a DC plug Arduino compatible kit with an ATmega328 chip. This clone acts just like an Arduino, and works with the latest Arduino software. For many projects it can even be preferable! The kit includes all parts necessary, the assembly is straightforward and well documented.
This is specifically designed for people who want to program Atmega328P's to turn them into Arduino bootloader chips using an AVR-ISP sketch, but it can also be used to make a 'standalone' AVR ISP programmer - so that you can program blank chips without a computer!
