great product, great support

some assembly required, but it's straightforward. Manufacturer support is excellent, prompt, and detailed.

Nice way to add tons of GPIOs to a RPI, lacks interrupts

Used it to simplify encoder wiring. I wish they would provide options to route interrupts to select RPI pins via solder jumpers. Instead the INT signals are routed to the respective IO headers, which defeats the purpose

Great Product!

It is great to have the ability to expand the Raspberry pi GPIOs using this product.

You need lots of IO? come and get it!

After Enabling I2C and downloading a small library, you'll be up to your ears in IO. You'll probably need a header extension it's a tight fit on a PI3b+.
