Adding GPIO pins to a Nano

Hi all,
I am running out of pins on a Nano and need to add to the GPIO. Can I use an MCP23017 with I2C to add more GPIO?

Secondly, if the answer is yes - how are the added pins addressed? Any refs?

Thanks!
John

hello john.buchowski,

please access pinmux spreadsheets via download center,
you may have customization to configure the pins as GPIO, and then flash the new configuration to the developer kit.

besides,
you may also refer to Configuring the 40-Pin Expansion Header by using Jetson-IO to simplify the configuration of the I/Os exposed by the 40‑pin expansion header.
thanks

Hi Jerry,
I need to add more GPIO pins, not reconfigure the ones already on the board. Please reread the question.

Thanks!

hello john.buchowski,

please check pinmux spreadsheets for the default pin configuration.
if you need more GPIOs, there’s pin selection to change it as GPIO pin for board configuration.
thanks
