NRF51822-QFABR7 vs NRF51822-QFAB-R-V3

[Jack Gratteau]

What is different between R7 and V3 ?

Data sheet say rev 3.3 - but that is just the rev of the data sheet

Suppliers have both R7 and R-V3 inventory

Does it make any functional difference ?

Thanks

Hi Jack, 

we do not use R or R7 in our IC markings, see  nRF51822 IC revision overview. I believe that the R stands for Reel, i.e. that the components are delivered in a reel. Any number after the R indicates the diameter,e.g. R7 is a 7inch reel. 

Best regards
