This May Pad kit is great (https://keyhive.xyz/shop/may-pad)
Also great options from keebio (https://keeb.io/collections/macropads)
The tidbit is also really cool! (https://nullbits.co/tidbit/)
Again, just options if you feel like this would be a cool project and you're cool with doing some soldering. Other people have suggested good pre-built solutions, and many macropads can do what you're looking for.
