Serial Success! (FOMOphobia)

Thanks to this little critter, a SMAKN MAX232CSE Transfer Chip RS232 To TTL Converter Module COM Serial Board, the Raspberry Pi was able to talk to the Betabrite LED sign for the first time. Huzzah!


A little bit too tired to write about it in any detail, but let’s say that all the things I was doing software-wise over the last several weeks were right, but I just needed this little piece of hardware to bring up the TTL voltage to RS232 levels.
