The MikroElektronika Expand 16 Click is a compact add-on board with a multi-port input, output expander. This board features the FXL6408, a fully configurable 8-bit GPIO expander from ON Semiconductor. It brings eight independently configurable input, output ports, with a 6mA output drive, when configured in the output mode. When configured in Input Mode, the FXL6408 monitors the input ports for data transitions and signals the baseband by asserting the interrupt output pin. This Click board makes the perfect solution for the development of applications where additional input, output are needed for switches, sensors, push-buttons, LEDs, fans.
