Description:

16 way I/O extension module of the 12C interface, adopts MCP23017 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-speed IIC interface. It the IIC frequency of 100KHz, 400KHz .7MHz. The 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.
