I saw some reports that TX & RX were labelled incorrectly in the reviews. This is also the case with all of the units I received. Labels on the board have TX/RX pins reversed. Removed one star for that, but they otherwise work great.

It worked as documented and desired. What more could I want?

I saw reviews that said the PCB was marked incorrectly, that the chip was a MAX232 instead of a MAX3232 and the chip overheated. I did not see any of these issues. All 5 of my boards had MAX3232 chips installed, were marked correctly and ran cool. Note that the "schematic" shown (also attached) is completely wrong. GND of the CPU is shown connected to RXD, CPU TXD is connected to GND and CPU RXD is connected to TXD. The correct connection is CPU GND to GND (obviously), CPU TXD to TXD and CPU RXD to RXD.I connected the board to a TI MSP430F5338 and it works fine at 115.2K when connected to my PC. I would have preferred that the 4 pin connector was ship separately as I used wires to connect the board, but I just wired to the back of the board. Not mentioned in the documentation is a red LED power indicator.

Great product for the money. Mine were all RS3232 chips and output correct voltage. Unfortunately, the pin labled txd is actually rxd and rxd is txd. A lame mistake by the maufacturer but once you know, they work well. Using this for serial testing with a LibreComputer "Le Potato" connected to pins 4,6,8,10 which map to /dev/ttyAML6 once you "ldto enable uarta". I would buy more but this came with 5x units. All set for four more projects.
