PCF8574 I2C LCD (1602, 2004) interface (til Arduino)
Varenr:
H11145

Dette er endnu et nyttigt IIC / I2C / TWI / SPI Serial Interface til din Arduino. Da pin-ressourcerne på Arduino-controlleren er begrænsede, kan dit projekt muligvis ikke bruge normal LCD-skærm efter tilslutning af en mængde sensorer eller SD-kort. Men med dette I2C-interface modul kan du realisere datavisning via kun 2 ledninger. Hvis du allerede har I2C-enheder i dit projekt, koster dette LCD-modul rent faktisk ikke flere ressourcer.
Egenskaber:
- Understøtter I2C-protokol
- LCD baggrundsbelysning kan slås til og fra via jumper
- LCD kontrasten kan justeres ved at dreje det blå potentiometer
- Modulet kan kaskadere op til otte displays.
- / A1 / A2 ændrer enhedens adresse via kortslutning af A0
- Standardadressen er 0x27
Tekniske detaljer:
- Størrelse: 42x19x15,3mm
- Vægt: 5g
- Forsyningsspænding: 5V (2,5...6Vdc)
This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.
Features:
- Support I2C protocol
- The power control with backlight can be set via jumpers backlight power supply is connected. Plug jumper to connect the backlight, then unplug the jumper is off backlight power supply
- The contrast can be adjusted by turning the blue potentiometer clockwise enhanced counterclockwise weakened.
- The module can cascade up to eight cascaded. / A1 / A2 modify the device address via short circuit A0.
- The default address is 0x27
Specifications:
- Dimensions: 42 x 19 x 15mm
- Weight: 5g
- Supply voltage: 5V (2,5...6Vdc)
