Product description

Description:

- 16 way I/O extension module of the 12C interface, adopts MCP23017 chip of MicroChip.
- Each IO can be discretionarily configured as input or output, and can set pull up resistort.
- The IO configured as input can start interrupt function. The IO interface has a strong driving capacity, and the sink current and pull current can reach 25mA.
- MCP23017 is a high- IIC interface. It supports the IIC frequency of 100KHz, 400KHz and 1.7MHz. The chip has 3 address pins, which can set up to 8 different addresses. So 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions.
- This module is flexible in configuration and strong in driving ability. There are many parallel connections.
