How many pieces is this listing for? These chips should be something like less than $2 or less
This doesn't seem to fit in a breadboard. What's a good way to test? Would it fit an ic socket and then in breadboard?
Do I read this right, that the price here is four times as high as it is at DigiKey?

Very happy with this, had some trouble finding the right libraries to get this working on esp32

If you use the adafruit library the code to control these will be almost identical to built in arduino pins. And they have built in input pullups although i wish they were input pulldowns its better than nothing. If you plan on using these with esp32 you'll need to find the 2.0.0 or 2.1.0 version of the adafruit library.

It works. I am able to expand my I/O ports!

It works great. I am able to use this MCP to expand my I/O pins with ease. I2C is a great interface to work with along with the MCP23017. I suggest looking at the Adafruit MCP23017 library for code examples.Pros:* It works as promised* Solid build* Breadboard friendlyCons:* Not as cheap compare to shift registers but the MCPs are easier to use

Can't say much, it works. Pins are fragile but this isn't a 16 gauge solid copper wire. No instructions which is also noted so don't expect this to be ready to go out of the box. I've accidentally wired it wrong a couple times and some reviews say this will kill it instantly. It's still going strong 24/7 after 4 months.

Work great. Cheaper other places but slow shipping.

Little pricy but you're paying for the quick shipping. They work great

Worked good until I did something where can't send voltage out of GPIO pins . Nice IC for adding GPIO to ESP8266 boards with 2 GPIO.

Works very well with the raspberry pi and the 'wiringpi2' i2c script using python3

Works!

I used this part to build a two player arcade system with a RaspberryPi.

Works as expected.

Bought this to expand the I/O capability of my pin limited Ardiuno Uno. Easy to use, using info readily available on the internet.
