LilyPad 328 Main board, Arduino

Description

The LilyPad Arduino is a microcontroller board designed for wearables and e-textiles. It can be sewn to fabric and similarly mounted power supplies, sensors and actuators with conductive thread so as to create interactive garments and accessories.

This LilyPad main board consists of an ATmega328 with the Arduino bootloader and a minimum number of external components to keep it as small (and as simple) as possible. The board can run from 2V to 5V. The latest version of the LilyPad supports automatic reset for even easier programming. The back side of the LilyPad is now completely flat! A surface mount programming connector is employed to keep the header from poking through.

Features

  • ATmega328 running at 8MHz
  • 14 x Digital I/Os (6 are PWM capable)
  • 6 Analog Input pins
  • 16KB flash (of which 2KB used by bootloader)
  • 1KB SRAM
  • 512 bytes EEPROM
  • Dimensions: 50mm outer diameter
