The FLORA is small (1.75" diameter,...

Add mega-storage in a jiffy using this 4 GB micro-SD card. It comes with a SD adapter so you can use it with any of our shields or adapters! Preformatted to FAT so it works out of the box with our projects. Tested and works great with our Wave shield, Data logger shield and GPS shield, and micro-SD adapter as well as any other device in the Adafruit shop that uses (micro)-SD cards! Please note! This is an SDHC card, and may not work with very...

USBtinyISP is a simple open-source USB AVR programmer and SPI interface. It is low cost, easy to make, works great with avrdude, has both 6 and 10 pin standard ISP cables, is AVRStudio-compatible and tested under Windows XP and MacOS X, it may or may not work with your specific Vista/Windows 7 system, please visit the Adafruit forums before purchase. Using this programmer and avrdude you can program any in-circuit "serial" programmable chip that...

Lithium ion polymer (also known as 'lipo' or 'lipoly') batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2500mAh for a total of about 10 Wh. If you need a smaller battery, we also have a 1200mAh model The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST...

The Teensy 2.0 is a complete USB-based microcontoller development system, in a very small footprint! All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port. This is the latest version, 2.0. Key Features: USB can be any type of device AVR processor, 16 MHz Single pushbutton programming Easy to use Teensy Loader application Free software development tools...

Toss out those FTDI cables and go USB-native with the ATmega32u4. After many months of back-orders, we finally received a shipment of these little guys and are excited to offer our breakout board. The little dev board keeps it simple, with just the bare essentials: Atmega32u4 - AVR core with USB capability. 32K flash, 2.5K RAM running at 16MHz Standard AVR 6-pin ISP connector for direct programming (when you need the extra space) Big...

This here is your standard A-B USB cable, for USB 1.1 or 2.0. Perfect for connecting a PC to your Arduino, USBtinyISP, or USB Boarduino (among other things). 3 feet / 1 meter long Color may vary!

The Teensy++ is a complete USB-based microcontoller development system, in a very small footprint! All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port. Its the big sister version of the popular Teensy board we carry, this board has tons of FLASH, RAM, pins and more. This is the latest version, 2.0. Key Features: USB can be any type of device AVR...

This here is your standard A-miniB USB cable, for USB 1.1 or 2.0. Perfect for connecting a PC to your Teensy, USB Lipo charger (among other things). Approximately 3 feet / 1 meter long Color may vary!

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! Comes unassembled with: Printed circuit board Blank ATMEGA328 with internal 1 MHz oscillator selected (default) 28-DIP socket 6-pin ISP AVR programming header 0.1uF ceramic capacitor 5mm diffused red LED Resistor for LED We suggest using this board in conjunction with a...

Red and black tinned wires with a 2-pin JST PH connector on the end. 4" / 100mm long. Matches up nicely with our Lipoly charger! We don't have the 'mating' version of this, with the receptacle - but we do have a long extension cable that can be cut in half. New! We now use genuine JST PH connectors for these cables so they are easy to insert and remove. For more information about JST PH connectors, visit the JST website

This is just the microcontroller burned with the USBtinyISP firmware code. If you're buying a kit, this is included. This is intended for people who are buying just the PCB or are experimenting with the kit and want a backup chip.

Programming AVR? Always Googling the pinout? Well, now no longer! It's rare to find a mini kit so elegant, it deserves its own Haiku. A simple breakout, 2x3 box header in the center, two 1x3's on the side. Plugs into any breadboard for neat wiring (in both nifty and clean senses of the word). Comes with a quality mini PCB, a 2x3 box header and a small stick of 0.1" header. Requires some light soldering to use: plug the 2x3 in on the top and...
