SparkFun Support and Front Desk will be closed on Thursday 11/14 from 1-2:30pm for a company event. Please plan to pick up your orders before or after this timeframe.
This is the LilyPad USB Plus, a sewable electronics microcontroller board controlled by an ATmega32U4 with the Arduino bootloader. It has a built in power supply JST (and recharge circuit) and an on/off switch with the only extra piece of hardware you need to program the LilyPad USB Plus being a micro-USB cable. We've also added an RGB LED in the dead-center of the board along with six white LEDs to act as a sort of bar graph. The LilyPad USB Plus was designed to streamline your next sewable project by keeping things simple and giving you more room to work while eliminating the need to sew a power supply.
It has fourteen sew tabs for connecting components with conductive thread. Four of these tabs are reserved for connecting power and ground of LilyPad sensors and accessory boards, and ten are input/output (I/O). For reference, each sew tab has a nearby label with its name and the pin number it is connected to on the ATmega32U4 chip at its center.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available in the LilyPad line but will also work with most other wearable e-textile lines. They’re even washable!
Please be aware that the Lilypad USB Plus is NOT supported on Windows 7/8 due to a lack of support drivers for those specific OS's.
Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education in e-textiles.
1- Press the RESET twice quickly and you should see a blue LED fading in and out for about 8 seconds.
2- Quickly, go to /Tools/Port and select the port labeled ‘LilyPad USB Plus.’ If it’s not there, get out of /Tools/Port, retry step 1 and then retry this step. You don’t have much time between pressing the button twice and selecting the port, so it may take a few tries to get this to work.
3- Once you have that com port selected, make sure you have the Arduino IDE set to a board type of ‘LilyPad USB Plus.’
4- Open up the ‘Blink’ example from /File/Examples/01.Basics/Blink.
5- Click the ‘upload’ button in Arduino.
6- Once you see ‘Uploading…’ appear in the status bar in Arduino, quickly double press RESET again. The ‘Blink’ sketch should upload and you will see a blinking green LED on the board. If that happens, the board is now recovered and ready to go.
7- If it doesn’t work, try step 6 again. The timing can be tricky to get this step to work and it may take a few tries to get the code to upload, but once it does, you’re in the clear.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
