I wanted to share this with the community because I love Arduino and wanted to give something back. ;D I do a LOT of breadboarding and very often need to communicate with my PC. Using a MAX232 is great but all those caps really take up room and get in the way… don’t they??
I began using the MAX233 about a year ago and it is exactly like a MAX232 except… GET READY!.. NO EXTERNAL CAPS!! Go here and check out the data sheet.
It even comes in a DIP package for us breadboarders! I guess there could be some limitations to having internal caps but I haven’t run into any!
Also, Maxim might send you free samples if you have a valid business address!
Go Vertical as Often as Possible
