Hi all
im sure this has been answered many times before but damned if i can find a decent answer.
if i have this right.. amps supplied by a psu can be ANY amount? I need to supply 3.3v to a esp-01 to program it. seems the mega does not supply enough amps. thats fine. the PSU i have will supply 3.3v at like 15 amps. (maybe as high as 40amps) as the esp only requires about 200ma it will only draw what is required? (using a mega to put the at commands on it to use it as a wifi client)
sure the device is only a $4au part but being where i am i cant just walk into a store and replace it if i fry it (perth australia is WAY lacking in electronics stores)
I am pretty sure that supplied amps does not matter as long as the voltage is correct
thanks in advance
Rob
