模块为 I2C 接口的 16 路 IO 扩展模块，采用 MicroChip 的 MCP23017 芯片。芯片功能完备，每个 IO 可 任意配置为输入或输出，可设置使用上拉电阻。并且配置为输入的 IO 都可以启用中断功能。IO 接口驱动 能力强，灌电流、拉电流可达 25mA。(Module for the I2C interface of the 16-way IO expansion module, using Microchip MCP23017 chip. The chip function is complete, each IO can Arbitrary configuration for input or output, you can set the use of pull resistance. And the IO configured for input can enable the interrupt feature. IO Interface Driver Ability, irrigation current, pull current up to 25mA.)
