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.

Specifications:

  • Chip used: MCP23017
  • Power: 2.7-5.5V (only 3.3V via μŠup)
  • Interface: I 2 C
  • Size: 43x20x5mm

Included in delivery:

  • 1pc LaskaKit MCP23017 I2C 16 bit I/O Expander

Remark:

  • This product is not a standalone functional unit and may require professional installation.
  • Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.

"Napájení: 2.7-5.5V (přes μŠup pouze 3.3V)" Pouze 3.3V přes μŠup je omezení samotného konektoru, nebo to má jiný důvod?

Důvod je ten, že uŠup konektory používáme jen na našich deskách s ESP32 a tudíž je tam jen 3,3V.

jak tento mobul komunikuje? v Textu je i2c ale ve specifikaci je SPI. Ktere je tedy spravne. Podle PDF ma komunikovat pres i2c ale mozna to uz zmenili. Dekuji za odpoved.
