Seems there are two errors:
- swap Rx/Tx on µC board,
- MAX232 cann’t be feed by 3.3V, you need to use a +5V external power supply.

Does anyone know of a max232 pre-assembled kit that uses SMT 232s and available in US? I only need two and don’t want to bother with the PCB/component ordering/packaging issues, but I want it to fit in a D-sub shell.

Max232 can works with 2.7 to 5.5 voltage supply. I have an experiment!

I’ve discovered my mistake. The pinout of a female null modem connector is different. 13-2 and 14-3 are the correct matches. Live and learn.

I’ve done exactly the schematic in the picture with electrolytic capacitors( with 1u instead of the 10u one), and pins 11 and 12( TX,RX) connected for loopback. The problem is that i don’t get anything in hyperterminal (COM1, 9600 baud, 8N1, flow none) or tera term. Any ideas to what the problem might be? Thanks.
