I just bought a (brand that cannot be mentioned because the company sells a counterfeit) Mega2560 R3 online.
I noticed a hairline crack on one of the capacitors.
It started me wondering just how old this unit is...?
The capacitor has 3 markings :
- line 1 : 8a
- line 2 : 47
- line 3 : 16V
Which I assume are date, capacitance and voltage.
Can anyone interpret the date code of "8a".
I am speculating - 2008 Jan.
Also the pcb has a code of 09-011-939.
I am speculating 2009 week 39.
Could someone confirm or advise otherwise please.
