ITEM NAME:MC23017 I2C Interface 16Bit I/O Extension Module Pin Board Iic To Gipo Conv M4F1 MC23017 I2C Interface 16Bit I/O Extension Module Pin Board Iic To Gipo Conv M4F1 This module is the 16 way IO extension module of the 12C interface, and built in the MCP23017 chip of MicroChip. The function of the chip is complete. 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. This module is flexible in configuration and strong in driving ability. There are many parallel connections. Operating voltage:3.0V-5.5V working temperature:-40 Celsius -125 Celsius Chip level:Industrial grade Parallel multiple:Up to 8 Driver：51 and Arduino Module size：65mm*19mm Power source input：3.0V-5.5V GND：Power negative electrode colour:green Material:PC+ metal Package Contents: 1 * Extension Module Pin Board 40 * PIN
