PCF8574 IO Expansion Board 8-bit I/O Expander I2C-Bus Evaluation Development Module

product description I2C interface, I / O expansion module, two I / O scalability eight I / O (up to eight PCF8574 can be expanded to 64 I / O at the same time). The access target board supports two interface types: pin or row seat. I / O expansion less than MCU microcontroller I / O resources. PCF8574, I2C interface, 8-bit parallel port. Size: about 48mm * 16mm. Color: mainly blue. Material: durable PCB board and metal. Size: about 48mm * 16mm. 100% new high-quality IO expansion module I / O expander I2C bus module. Lack of I / O resources for MCU I / O expansion. Two types of access to target board interface are supported: Pin or row of seats. I / O Expansion Module, Two I / O Expansion Capabilities Eight I / Os (up to eight PCF8574s can be used at the same time, expanded to 64 I / O Expansion Modules, support for I2C bus cascading (via pin-to-pin docking Use multiple I2C modules simultaneously) O). The access target board supports two interface types: pin or row seat. PCF8574, I2C interface, 8-bit parallel port. product information Packing size 6.3 × 3.4 × 0.5 inches Product weight 0.8 oz
