I need to put Ascii codes into my computer through USB by pressing a SPST instead of a keyboard. This board works great

But it has more than I need for this project. I only need to input 4 codes. Is there a board that will do this for me?
Thanks in advance

Re: SPST to Ascii code
We have a whole section of parts for mechanical keyboards:

The keys are mechanical switches with various kinds of touch response. They fit in sockets that make wiring multiple ones easier:

and we have PCB breakouts that hold the sockets:

You can also use regular tact switches and connect them to a dev board like the Kee Boar Driver:

Re: SPST to Ascii code
Any of the boards with "native USB" should be able to emulate a keyboard.
A QT Py M0 should handle 4 switches (or up to 11) with no problem.
(although, the last time I actually DID this, I tore apart a cheap keyboard and connected switches (foot pedals, actually) where a couple of the keys would have gone. The actual electronics inside most keyboards is pretty small.)
