Has anyone had success using the robotdyn Mega 2650 Pro Embed?
Mine arrived yesterday but I can't get it to appear as an option in the IDE. Tried burning the bootloader to it but it throws back "Error while burning bootloader".
Thanks in advance
I haven't used this exact board but I have used a heap of other Robotdyn boards and I've been quite happy with them.
First off:

Unless you have an external programmer you can't burn the bootloader so that response is to be expected.

What do you mean by this? Does the serial port not show up in the IDE? If so, have you installed the CH340 drivers? Does anything show up in Device Manager when you plug in the board (assuming you are using Windows)?
Does the onboard power LED come on when you plug the board in?
So I can't even set up a known good arduino as arduino isp and burn the bootloader?
Spot on yeah the serial port doesn't show up in the IDE. I've installed the CH340 drivers and I get something showing up in device manager but not the way a 'normal' Mega2560 shows up. I'm away from my windows pc now so can't remember what it shows up as. Something along the lines of 'unknown USB deivce'.
With power connected the power LED lights up and the LED connected to pin 13 blinks every second.

You certainly can do that. The bootloader isn't you'r problem here though.

Have you used other CH340-based boards before? The symptoms you describe are what you'd expect when you're missing the correct drivers. How did you install the drivers, and where did you get the drivers from?
is this board 5 or 3.3v , or can i choose them?
there are 2 voltage regulators on board ..

The board is 5V- if you look at the schematic the main IC is supplied by the 5V regulator.
If the board does not have an 'intelligent' USB-to-TTL adapter, it will only show as a COM port and not as a Mega.
