Product description
LilyTiny is a small microcontroller from SparkFun, inspired by the LilyPad series. It is designed for textile and wearable projects where you want to create light effects with LEDs without needing a larger controller. The circuit board measures only 20 mm in diameter and 0.8 mm in thickness, making it easy to sew onto or integrate into fabric.
The board comes pre-programmed with four different LED effects: blink (on/off), heartbeat (pulse), breathing fade, and random fade. You can connect up to four LEDs directly and achieve effects without writing any code. For more advanced applications, the microcontroller can be reprogrammed via the ICSP connectors on the back.
The advantages of LilyTiny are its simplicity, compact size, and the ability to create visual effects right away. This makes it particularly useful in e-textile projects, jewelry, or prototypes where there is no space for a larger microcontroller. It also works well as an educational component to demonstrate how a microcontroller can control LEDs.
The limitations are that it only offers a few fixed patterns unless reprogrammed, and its power handling is limited to simpler LED projects. If more LEDs or higher current are required, external drivers are needed.
Processor: ATtiny85, programmable with Arduino IDE
Supply voltage: 5 VDC
