The MCP23S17-E/SS is a 16-bit I/O expander with SPI interface from Microchip. It is a general purpose device that provides an easy way to add more I/O pins to a microcontroller. The device can be used to expand the number of I/O pins available on a microcontroller, allowing more complex control and ..
The SX1509 Breakout is a 16-channel GPIO expander with an I2C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin control. It can produce PWM signals, so y..
