We’ve updated the Simple board to create the LilyPad USB by replacing the classic ATMega328 with the new ATMega32U4. Not only does that mean that it’s running a variation of the latest and greatest bootloader, but it also means no more FTDI Basic! The only extra piece of hardware you need to program the LilyPad USB is a micro-USB cable, since the new IC has built-in USB support. The LilyPad USB is also officially supported in the Arduino IDE as of version 1.0.2! ## Pricing - **Price:** $52.35 (inc GST) — $47.59 AUD, exc GST - **Quantity discounts:** 5+ $46.16 (exc GST) · 25+ $45.21 (exc GST) · 100+ $43.31 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 17 and Aug 24. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DEV-12049:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DEV-12049:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The LilyPad Simple just got a whole lot… simpler. SparkFun have updated the original LilyPad Simple board to create the LilyPad USB by replacing the classic ATMega328 with the new ATMega32U4. Not only does that mean that it’s running a variation of the latest and greatest bootloader, but it also means no more FTDI Basic is needed to program your Lilypad! That's right! **The only extra piece of hardware you need to program the LilyPad USB is [a micro-USB cable](https://core-electronics.com.au/micro-usb-cable.html)**. The new IC has built-in USB support. The LilyPad USB is also officially supported in the Arduino IDE as of version 1.0.2! Just like the LilyPad Simple, this board features a JST socket ([read more on JST here](https://core-electronics.com.au/tutorials/what-is-a-jst-connector.html)) so you can directly connect any of [our 3.7V Li-Po batteries](https://core-electronics.com.au/power-batteries/liion-lipoly.html) for power. There's also an onboard power switch so you can turn it off when you’re not feeling particularly blinky. These boards were 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. The LiPo battery is even rechargeable through the board, no more special external LiPo chargers required, just connect your board to a USB power source! 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. They’re even washable! **Note:** A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles and also to Arduino LLC to help fund continued development of new tools and new IDE features. **Dimensions:** - 50mm outer diameter - Thin 0.8mm PCB **Documents:** - [Schematic](https://core-electronics.com.au/attachments/localcontent/Lilypad_Arduino_USB_v12_65796a3f146.pdf) - [Eagle Files](https://core-electronics.com.au/attachments/localcontent/Lilypad_Arduino_USB_v12_2051542c4f9.zip) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/ATmega16U4-32U4_78368f0d4f9.pdf) (ATMega32U4) - [Firmware Note](https://core-electronics.com.au/attachments/localcontent/32U4Note_302100bd229.pdf) - Arduino Hardware Page - Arduino Quickstart Guide - [Arduino Add-on Files](https://core-electronics.com.au/attachments/localcontent/master_754603faaec.zip) - [GitHub](https://github.com/sparkfun/SF32u4_boards) (Design Files & Example Code) ## Guides for this product - [E-Textiles / Wearables Compared: LilyPad vs GEMMA vs Microbit](https://core-electronics.com.au/guides/micro-bit/e-textiles-wearbles-compared/) ## Videos for this product - [E-Textiles / Wearables Compared: LilyPad vs GEMMA vs Microbit](https://core-electronics.com.au/videos/e-textiles-wearables-compared-lilypad-vs-gemma-vs-microbit) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/l/i/lilypad_arduino_usb_-_atmega32u4_board__dev-12049__01.jpg)
