Difference between reference designs of nRF52840

[Or]

Was looking through the reference designs you have in github.

I figured the difference between nRF52840_qiaa_var1 (what is qiaa ?) and nRF52840_qiaa_var2 is the use of the DC/DC converter.

I cant find any difference between the rest and var2 .. all seem the same.

Maybe add a README file describing each plus considerations for/against using that particular reference design ?

Or said:

what is qiaa

they are the bit of the part number that identify package & memory size:

Hi,

 

As described in github these Eagle reference designs are not the official, verified and regularly maintained reference designs. The difference between the variants are described in the PS, Altium reference layouts are found in the product pages.

 

best regards,

Andreas
