Re: I did it again.. i plugged the arduino pins on reverse

Cesar? EA3IAV You may have blown your Arduino NANO, or maybe not.? In the later picture the red POWER indicator LED is ON, indicating that your NANO is receiving power, but that does not really tell you the state of the on-board voltage regulator or the micro-processor itself.? You can test your NANO and the associated LED but the process may not be easy unless you are already familiar with writing software to the NANO.? If you are familiar with writing software to the NANO you can overwrite the existing BITX software with something like the "BLINK" program that is in Examples in the Arduino IDE.? If this is successful (if the LED actually blinks) it would indicate that at least part of the NANO micro-controller is working. Problem with doing this is that you have to overwrite your original BITX operating system with BLINK code, and then re-write the BITX software back into the NANO after doing the BLINK test.? There is nothing particularly unique about the Arduino NANO that is used in the BITX or uBITX transceivers.? Any Arduino NANO that has the standard NANO pinout should work after you have programmed it with the appropriate BITX software.? At present I see NANO boards going for about US$3.25 each on Ebay.? New NANO boards from most vendors come pre-programed with the boot-loader and the BLINK program. /g/BITX20/attachment/21076/0/Raduino%20Pinout.pdf Arv?
