Title: Does the LilyPad have I2C pins (TWI)?
Post by: willielenk on Jun 11, 2014, 09:52 pm
I have an Arduino LilyPad that i'd like to use as an I2C master device. The board overview on the website mentions nothing about I2C pins, but the Arduino LilyPad USB board overview does mention the I2C pins. Does the regular lilypad have this capability? If so, which pins are SDA and SCL?

If your Lillypad  has the basic ATmega328V  (or 168V) processor then the I2C pins will be A4 (SDA) and A5 (SCL), just like on the Arduino UNO.
