SX1509 16-channel I/O Output Module for GPIO Keyboard Voltage Level LED Driver
Size : 36mm*25mm*3mm
This handy device also contains a fully programmable LED driver and a keyboard scan engine, enabling continuous keyboard monitoring of up to 64 keys! Since the I/O bank can operate between 1.2V and 3.6V (with a 5.5V tolerance), independent of the core and other devices, the device can also be used as a level translator.
