WeatherDuino Pro2 PLUS Receiver - Notes about Assembling and Power On
As said before, complete the assembling of the the Pro2 PLUS board is very easy, mainly because all SMD parts are already assembled, however, as happen when you deal with an electronic circuit, you should have some cares to finalize the assembling. The board includes some static sensitive IC's, so take the usual cares when dealing with this kind of devices. If you need Google for more info about this matter.
No matter what you have read somewhere in any post, resist to the temptation to apply power to an unfinished board, you gain nothing and risk to damage it. An unfinished board, is a board that doesn't have all the required parts installed, and all means exactly all (RTC module, ATM and / or Temp / Hum sensors, radios RX and TX, TFT display and the controller board).
Now, if you already have all the parts installed, its time to apply power to the board, for programming it.
There is a very important procedure, that should always be done on the Meduino Mini Mega board before installing it onto the WeatherDuino Pro2 PLUS receiver board.
Always remove the diode illustrated on the picture bellow.
A failure of doing this procedure main lead to permanent damages in the WeatherDuino Pro2 PLUS receiver, in the event that the main power supply fail, and it remains powered by USB.
Removing this diode, ensures that the Receiver only gets power when powered by through the external power supply.

Before connecting any power supply to the Pro2 PLUS, always measure its output voltage with a voltmeter. Make sure that it is in the range of 7.5V to 9V.
Powering the system with a voltage greater than 9V will make that the voltage regulators produce excessive heat.
Under normal work conditions the 3.3V voltage regulator runs just slightly warm, and moderately hot when the TFT backlight is on, but never very hot.
