Hi Prateek,

What is the no-load voltage of your power supply?

*"When the Tiny V2.11 powers up, a LED glows. This LED used to glow
 when we connected a standard 9V battery. However the LED no longer
glows. On checking with the multimeter, I found that the board is
getting a voltage in the range of 4.8V to 5.2 V. Is this sufficient to
power up the LED? Or is it a problem with the board or should I change
the battery(use one with higher voltage rating)  and try again? We are
a Paparazzi newbie team. Any help would be greatly appreciated"*

We were advised to switch to an alternate power source with higher current
rating. We used a 12V adapter with 1A current rating. However, the LED is
still not glowing and the board is getting a voltage of around 4V. Is there
any way to troubleshoot this board?
