MCP23017-E SS I2C Interface 16-Channel IO Expansion Module Compatible IIC Input and Output Expansion Board
- This module is the 16 channel IO extension module of the 12C interface, and built in the MCP23017 chip of MicroChip.; Each IO can be arbitrarily configured as input or output, and a pull up resistor can be set, and the interrupt function can be enabled for the IO configured as input. The IO interface has a strong driving capacity, and the current and current can reach 25mA.; MCP23017 is a high-speed IIC interface. It supports the IIC frequency of 100KHz, 400KHz and 1.7MHz.; The chip has 3 address pins, which can be set up for 8 different addresses. So 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions.; The chip has 3 address pins, which can be set up for 8 different addresses. So 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions.; NOYITO MCP23017-E SS I2C Interface 16-Channel IO Expansion Module Schematic Document
