PCF8575 I2C 16 bit I/O Expander

Product detailed description

If you are low on I/O pins, it's not a problem to add some. All you need is this module. This module expands the number of input/output pins by 16. And because it communicates over the I2C bus, it takes only 2 I/O pins

The device is equipped with a 16-bit quasi bidirectional I/O port (P07-P00, P17-P10), including latch outputs with high current supply for direct LED drive. Each quasi bidirectional I/O can be used as input or output without using a data direction signal.

Thanks to the adjustable three-bit addressing it should not be a problem to connect up to 8 such circuits together

The module contains 3x jumpers and allows to change the address, for more info see datasheet R1, R2 and R3 are pull-up resistors.
