What is it?

AW9523 is a 16 I/O Port-Expander. Very cheap and easy to use with Arduino.

If you want to support me please order directly via my homepage: ripper121.com Tindie cuts nearly 15% off (I think because of the low article price)

The PCB has a pin spacing of 2.54mm / 0.1 in, so perfect for Perfboard or Breadboard.

Arduino Library: Github

Why did you make it?

I looked for a cheap and small port Expander and found that part on LCSC, so I created this PCB.
