MCP23017-E/SP
by MICROCHIP(美国微芯)
Running short of microcontroller GPIO is a common reason to add Microchip's MCP23017-E/SP, an I²C I/O expander for buttons, indicators and other digital signals. Its free KiCad set pairs the 28-pin schematic symbol with DIP-28_L34.6-W7.3-P2.54-LS10.2-BL, a footprint containing 28 pads, and includes a 3D model. The through-hole DIP-28 format suits boards where a leaded device is preferred for assembly or prototyping. These files come from a conversion that 2 ProtoFlow engineers have used in real designs. Continue working with the expander by opening it directly in ProtoFlow.
