Product Details


IC/Module: MCP23017 Port Expander

MCP23017 is a 16-bit remote bidirectional I/O port expander with configurable interrupt output pins. The 16 I/O port bits are divided into two 8-bit ports (marked HD1 and HD2). It has I2C clock speeds of 100 kHz, 400 kHz, or 1.7 MHz for higher throughput applications. .

Expand 2 click Vs Expand click?

Expand 2 click is introduced as the sequel to the original Expand click. Expand 2 click uses MCP23017 expander whereas the original version includes the MCP23S17 chip. The only feature that differentiates these two versions is the use of I2C communication interface, instead of SPI. .

SMD Jumpers

Expand 2 click features four zero-ohm SMD jumpers. The PWR SEL is used to select between 5V or 3.3V power supply, and three hardware ADDR SEL allows the user to select the device address.
