{"title":"LilyPad Arduino USB - ATmega32U4 Board","handle":"lilypad-arduino-usb-atmega32u4-board","url":"/products/lilypad-arduino-usb-atmega32u4-board","description":"The LilyPad Arduino USB is a sewable microcontroller board built around the ATmega32U4 with native USB support — just plug in a micro-USB cable to program, no external FTDI adapter needed. Officially supported in the Arduino IDE, it runs at 3.3V and features a JST connector for a rechargeable LiPo battery with onboard charging.\n\nDesigned for wearable e-textile projects, the LilyPad features large sew-tab pads for stitching into clothing with conductive thread. The thin 0.8 mm PCB and 50 mm circular form factor keep things compact and comfortable. An onboard power switch lets you turn off your project when not in use.\n\nKey Features\n\n\nATmega32U4 – Built-in USB; program directly via micro-USB cable\n\n3.3V Operation – Safe for wearable and e-textile projects\n\nOnboard LiPo Charging – JST connector with built-in battery charger\n\nPower Switch – Turn your project on and off easily\n\nSewable Pads – Large pads designed for conductive thread\n\nThin PCB – 0.8 mm thick, 50 mm diameter for wearable comfort\n\nArduino IDE Support – Officially supported from version 1.0.2+\n\nWashable – Designed to withstand gentle washing\n\n\nIdeal For\n\nWearable electronics and e-textile projects\nInteractive clothing and costumes\nSewable LED and sensor projects\nLearning Arduino with wearable tech\n\n\nSpecifications\n\n\nMicrocontroller: ATmega32U4\n\nOperating Voltage: 3.3V\n\nDiameter: 50 mm\n\nPCB Thickness: 0.8 mm\n\n\nPackage Contents\n\n1× LilyPad Arduino USB Board\n\n\nResources\n\nArduino Quickstart Guide\nSchematic (PDF)\nATmega32U4 Datasheet (PDF)\nGitHub – Design Files & Examples\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":10638,"title":"Default Title","sku":"SF-DEV-12049","price":62.73,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":129,"option1":"Default Title"}]}
