특징

  • Expand 16 Click is a compact add-on board with a multi-port I/O 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 I/Os are needed for switches, sensors, push-buttons, LEDs, fans, and more.

  • HOW DOES IT WORK?

    Expand 16 Click is based on the FXL6408, a fully configurable 8-bit GPIO expander from ON Semiconductor. The input default values can be programmed independently, allowing customized input detection. All inputs can be configured with pull−up or pull−down resistors to pre−bias the inputs in open−drain or non−driven applications. The FXL6408 is designed to allow voltage translation from levels as low as 1.65V and up to 4.0V. For this purpose, you can supply the FXL6408 with an external voltage source over the VEXT terminal. The choice between the external voltage and the 3.3V from the mikroBUS™ socket for the voltage reference input of the I/O expander can be set over the VDDIO SEL jumper.

    Expand 16 Click uses a standard 2-wire I2C interface to communicate with the host MCU, supporting clock frequency up to 400kHz. The I2C address can be selected over the ADDR SEL jumper. The FXL6408 has three reset options: power-on reset, over the software, and the RST pin by writing the logic LOW. When the event occurs, the I/O expander will assert the host MCU over the interrupt INT pin.

    This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
