描述

PCF8575 IO 擴展模組 PCF8575 擴展板 I2C通信 控制16 個 IO 端口 ( 針腳未焊接)

I / O引腳用完了嗎?這個功能強大的模塊允許用戶僅使用兩個I / O進行控制即可擴展到最多16個I / O!PCF8575 IO 擴展模組 通過I2C接口控制,並具有16位準雙向輸入/輸出引腳。PCF8575 IO 擴展模組 板載3.3V電平轉換器電路上,如果不焊接VCC-VDD焊盤,則PCF8575的電平為3.3V。如果焊接,其電平將與VCC相同特徵:可用庫:PCF8575工作電壓:2.5-5.5V DC工作電流:100mA(MAX)I2C地址:0x20(默認),可以通過焊接A1和A2選擇墊進行修改。16個可單獨尋址的引腳。每個引腳均可配置為輸入或輸出開漏中斷輸出引腳,用於輸入更改中斷。非常適合UNO R3和其他MCU控制簡單的繼電器,蜂鳴器,按鈕,LED。

PCF8575 I2C IO Extension Shield Module 16 I/O Port Expander Arduino PI

Description:

  • 100% brand new and high quality.
  • Have you run out of I/O pins? This great module allows the user to expand up to 16 I/O using only two I/O for control! The PCF8575 is controlled through an I2C interface and features 16-bits of quasi-bidirectional input/output pins.
    Onboard 3.3V level converter circuit, if you do not solder VCC-VDD pad, the PCF8575 level is 3.3V. If you solder it, the level will be the same with VCC
  • Features:
    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 UNO R3 and other MCU to control simple relay, buzzer, button, led.
  • Size: 4×2.1cm/1.57×0.83inch
  • Quantity: 1 Pc
