Sobre este producto

Product Description:This powerful module allows users to expand to up to 16 I/Os using only two I/Os for control. PCF8575 is controlled via an I2C interface and has 16-bit quasi-bidirectional input/output pins.On the onboard 3.3V level converter circuit, if the VCC-VDD pad is not soldered, the level of PCF8575 is 3.3V. If soldered, its level will be the same as VCC.Product Features:- for Arduino available library: PCF8575- Working voltage: 2.5 - 5.5VDC- Working current: 100mA(MAX)- I2C address: 0x20(default),can be modified by soldering A1 and A2 selection pads.- 16 individually addressable pins.- Each pin configurable for input or output.- Open-drain interrupt output pin for input change interrupt.- Great for Arduino R3 and other MCU to control simple relay, buzzer, button, led.Package Includes:3 X PCF8575 IO Expander Board Module
