While checking the standard parts on JLCPCB, I came across a Chinese [[i2c]] GPIO extender known as AW9523B ([https://ipfs-pin.com/ipfs/QmQK9XdJ5D8aZySKUs2EvwPcv1q9PFZV9Ao15szbR2BAfK/AW9523B.pdf datasheet]).

This part is relatively unknown - at least outside China, but it does have a really interesting feature and that is the ability to drive [[leds]] by controlling the [[led]] current.

The AW9523B is only available in a [[QFN]] package and because these are really hard to hand solder, I decided to create a simple breakout board for this part:
