Sweet little board.

You'll need to pay attention to your project, though. I checked XBit's website. The board is available with either a 5V or 3V3 level shifter.
I'm only wearing black until they find something darker.

You can also get Arduino shield adapters so that you can use Arduino shields with the RPi.

AB Electronics have just released an expansion board which supports RS232 and 1-Wire.

There are many available.
Note: The module must have a MAX3232 chip (not MAX232) and the chip or module needs to be powered by 3V3 (not 5V).
Some info on my web site: http://home.budget.net/~klricks/Comp/RPi/Serial.html
Unless specified otherwise my response is based on the latest and fully updated Raspbian Stretch w/ Desktop OS.

If you want to use the GPIOs at the same time.A 3-row GPIO extended board is a good choice.

If you are using RPI B+ board,the B+ GPIO to B GPIO convert board is a nice choice.So you could use all your RPI B module add-ons in the RPI B+ board.

Does anyone have experience with this seemingly(?) new GPIO Serial Port Expansion Board RS232 For Raspberry Pi (SKU:1102755) ?
It costs 15US$ on ebay and aliexpress, so the banggood link seems to be the cheapest.

I would need a male-to-male gender changer, for 0.69US$ :x

Question: Does one need to install a driver, or are RS232 shields functional right away like Plug'n Play?

Hello, i've got that BG serial board. As soon as the raspi is powered, the green LED on the BG serial board lights up.
I am on the latest Raspbian Jessie, and i deleted the serial-console entry; things seem to look good so far:
Image
So how do i know, by which simple raspi tests/commands or program/utility, that my Pi Hat and its RS232-port is fully functional and working perfectly as it should? I have connected my logging digital multimeter (LDMM), with the help of a male-male gender changer, to the RS232-port, thus the BG serial board should be receiving data/signals all the time.

Btw i do have Raspbian beta-software for my LDMM but it seems that the software is not receiving any data/signal thru the raspi/Pi Hat/Gender Changer, so i need to question the functionality of the Pi Hat first!

Thanks in advance for some help or pointers!!

I have the same board and had a heck of a time getting it to work on my Stone TFT display board. I found the C soure code that's found in here works ok and tried communicating with my laptop. I used my laptop to setup the TFT display and couldn't figure out why it wouldn't work on the Raspberry Pi3. Well, I reversed the TXD and RXD wires on the TFT display and it started working just fine. Likely because the cable for Pi to Laptop was (I forgot the term) but made for computer to computer communictaion where the RX/TX terminals are reversed in the cable. Sometimes it's stupid simple things that get stuff working. Good luck with your project.
