Arduino LilyPad Main Board ATmega328P

Description

Overview The LilyPad 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. The board is based on the ATmega168V (the low-power version of the ATmega168) or the ATmega328V. Summary Warning: Don't power the LilyPad with more than 5.5 volts, or plug the power in backwards: you'll kill it. Microcontroller ATmega168V or ATmega328V Operating Voltage 2.7-5.5 V Input Voltage 2.7-5.5 V Digital I/O Pins 14 (of which 6 provide PWM output) Analog Input Pins 6 DC Current per I/O Pin 40 mA Flash Memory 16 KB (of which 2 KB used by bootloader) SRAM 1 KB EEPROM 512 bytes Clock Speed 8 MHz Programming The LilyPad can be programmed with the software. *Note*, the LilyPad should only be programmed with software versions 0010 or higher. You can program it with earlier versions, but all of the time related functions will be off (twice as slow as they should be). The ATmega168V or ATmega328V on the LilyPad comes preburned with a bootloader that allows you to upload new code to it with the software. You can also bypass the bootloader and program the ATmega through the ICSP (In-Circuit Serial Programming) header; seethese instructions for details. Power The LilyPad can be powered via the USB connection or with an external power supply. If an external power supply is used, it should provide between 2.7 and 5.5 volts. This can come either from an AC-to-DC adapter (wall-wart) or batte
