LilyPad Arduino Simple Board
The LilyPad Arduino Simple Board is a streamlined, sewable microcontroller designed for e-textile and wearable projects. Built around an ATmega328 with the Arduino bootloader, it features a built-in LiPo battery socket and on/off switch — so you can plug in a LiPo battery directly and eliminate the need to sew a separate power supply into your project.
Developed by Leah Buechley and SparkFun, LilyPad boards feature large conductive sew pads for attaching with conductive thread, and are designed to be washable. The Simple board trades some pin count for a cleaner, more compact layout with integrated battery charging via the MCP73831 IC.
Key Features
- Microcontroller – ATmega328 with Arduino bootloader
- Built-in LiPo Socket – Plug any LiPo battery directly into the board
- On/Off Switch – Onboard power switch for easy use in wearables
- Battery Charging – Integrated MCP73831-based charging circuit
- Sewable Design – Large conductive pads for conductive thread connections
- Washable – Designed to survive garment washing
Ideal For
- Wearable electronics and e-textile projects
- Sewable Arduino projects with LiPo battery power
- Fashion tech, interactive costumes, and smart garments
Note: Due to the added battery charging circuitry, the Simple board cannot power devices from the FTDI header — Bluetooth Mate and similar FTDI-powered accessories are not plug-and-play compatible with this board.
