Haha, we built this internally to use with Axiom scanners in our fulfillment centers which use RS232 interface, those scanners are 20 years old.

I convinced my boss to let me sell these as open source since we found many cool IOT uses for them around the office as well, that's why you are getting the RS232 on there but most people probably will not need that feature, but hey... it is there if you need it :)

It's a reflection on a great workplace culture to share like this. It's not the board for me, but nice you released it anyway. When those MAX232 chips came out many years ago they blew our minds having the charge pump for the negative voltage. Too bad we could never buy them at the time a the lead time was so long.
