Description
This is the I/O extended module, which uses for the I2C interface, you can use two of the module to extend 8 I/O. Support cascading, and you can use at most 8 modules to extend 64 I/O at the same time.
Specifications:
- 8 bi-directional data lines
- Loop-thru feature allows expansion of up to 8 modules / 64 data lines
- I2C interface with jumper adjustable addresses
- Interrupt output capability
- 3.3V and 5V are compatible.
Module Pinout:
The connections to the module are straightforward.
- Supply 3.3 or 5V power and ground.
- Connect I2C SCL and SDA lines to the same on the MCU.
