MIKROE-4853

Expand 9 Click PID: MIKROE-4853 Expand 9 Click is a compact add-on board that contains a multi-port I/O expander. This board features the SX1509QB, the world’s lowest voltage level shifting GPIO expander from Semtech Corporation. The SX1509QB comes in a 16-channel configuration and allows easy serial expansion of I/O through a standard I2C serial interface. It also has a built-in level shifting feature making it highly flexible in power supply systems where communication between incompatible I/O voltages is required, an integrated LED driver for enhanced lighting, and a keypad scanning engine to implement keypad applications up to 8x8 matrix. This Click board™ provides a simple solution when additional I/Os are needed, suitable for low-power portable equipment, keypad scanning, driving LEDs, and many more. Expand 9 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket. Specifications Type Port expander Applications Can be used for low-power portable equipment, keypad scanning, driving LEDs, and many more On-board modules SX1509QB - 16-channel lowest voltage level shifting GPIO expander from Semtech Corporation Key Features Low power consumption, integrated LED driver for enhanced lighting, on-chip keypad scanning engine, interrupt and reset feature, selectable I2C slave address, and more Interface I2C ClickID No Compatibility mikroBUS™ Click board size L (57.15 x 25.4 mm) Input Voltage 3.3V Resources mikroBUS™ mikroSDK Click board™ Catalog Click boards™ Downloads AP2112 datasheet SX1509QB datasheet Expand 9 click 2D and 3D files Expand 9 Click schematic Expand 9 click example on Libstock Powered by TCPDF (www.tcpdf.org)
