Pcf8574 arduino uno specs - Arduino - Wire
The Arduino Due has two I2C TWI interfaces SDA1 and SCL1 are near to the AREF pin and the Uno, Ethernet: A4 (SDA The Wire library uses 7 bit addresses.

AXE033 SERIALI2C LCD The serial LCD and clock module allows microcontroller systems (e. g. PICAXE) to visually output user instructions or readings, without the need.
See the Wire library page for information on the I2C TWI library in Arduino. Share.
I destroyed an 5V 16Mhz Arduino Pro Mini and a PCF8574 I2C port extender and I wonder how. Obviously it can be many things (ESD, overvoltage, etc. ). But I suspect.
