Note: An internal 4.7μF bulk capacitor has been included on the module. For those application that
with heavy GPIO usage and/or current draw, it is good design practice to add additional bulk
capacitance as required for your application.
General Purpose I/O:
The general purpose I/O is organized as one port enabling access and control of the 32 available
GPIO pins through one port. Each GPIO can be accessed individually with the following user
configurable features:
 Input/output direction
 Output drive strength
