Hi,
I had an "accident" with by arduino uno last week and fried the voltage regulator so it was giving way to high output voltage. It fried the atmega, but I was hoping the GSM shield would be ok.
When I received a new arduino today I tried to troubleshoot my gsm shield. the LMZ 12002 simple switcher has 5V input but is delivering 1.5V out. Which to my understanding is to low to power the circuit.
Is the LMZ 12002 simple switcher broken, or can it be something else.
Any suggestions would help
Thanks.
