Each I/O pin defaults as an input at power on. Sending the appropriate commands will switch them to an output
and you can also invert the polarity of each pin as well via I C. Read on to the Qwiic GPIO Arduino Library and
Python package sections for more information on how to configure and interact with these pins.
Qwiic and I C Interface
As you have come to expect with Qwiic boards, the connections for the I C bus (
SDA
,
SCL
,
GND
and
3.3V
) on the
Qwiic GPIO are broken out to a pair of Qwiic connectors as well as standard 0.1" spaced PTH pins for those who
would prefer to solder to them. The default I C address for the Qwiic GPIO is
0x27
.
Solder Jumpers
If you have never worked with solder jumpers and PCB traces before or would like a quick refresher, check
out our How to Work with Solder Jumpers and PCB Traces tutorial for detailed instructions and tips.
The Qwiic GPIO has six solder jumpers to configure the board labeled
I C
,
PWR
,
INT
,
A0
,
A1
and
A2
. This
section covers what each jumper's functionality is and how to configure them.
