Albert,
Thanks for your reply. I have contacted your engineer as you mentioned.
I haven’t been able to test your alternative method fully yet, as I don’t have an external power supply to hand just now. Using a 9V battery powered up the board okay, but the 5V rail is only hitting 3-4V - not enough to run my LCD screen. Although I guess it’s not a fair test when the board has a damaged component.
Out of interest, does the stalker v2 use the same component?
Thanks,
Jo
