**Q: Is it possible to purchase these boards without the headers soldered on?**
A: all is the finished

**Q: What type of external antenna connector is used on this board?**
A: buy 2.4G wifi ipex antenna

**Q: do you have to modify the board, i.e remove a resistor to get the external antenna to work? Because just connecting one doesn't make a difference.**
A: You just have to connect the antenna. At best you get a 6 dB improvement, most of the time less. So it is difficult to see the difference.

    This board works, but is tricky to set up.
  

*by K***R on Reviewed in the United States on August 27, 2021*

This board works fine but there is one thing to note. Make sure you use the correct mapping of files when burning the firmware to the flash. This uses a 4 mByte flash, so you need to find a .bin file set that matches. The factory all in one binaries I found I could not get to work. Once you get past this the board works great. I went to the makeraI website and followed the ESP8266 programming instructions, using the NonOS 1.7.4 AT set, using the 4MB location table.

    They have it all! (Well maybe not check subsequent comments)
  

*by R***S on Reviewed in the United States on June 26, 2023*

These things are amazing, they have the power of the Mega, they have a Wi-Fi chip built on, which you can use a variety of ways but connecting it to one of the serial ports is my favorite. It has external Wi-Fi antenna connection point, it’s very reasonably priced!Having used this board I have found one issue that I have not been able to resolve, it seems that it doesn't have a lot of power, which shows up when you add a shield to it. I added a DMX Shield but the board will not power it (my belief), if you take a regular Mega board (no integrated WIFI) the DMX shield works great. Still looking for answers but this maybe a problem - UPDATE I was using a USB hub, that could not supply enough power, removing that and coming directly from Computer solved power issue!

    Wrong cord sent
  

*by M***N on Reviewed in the United States on November 6, 2023*

Board seems fine. They sent the wrong cord for it though, which is annoying.
