there are 4x 10µF 1206 caps on the board :idea:
C1, C2, C6, C17

I figured out some bug in the two BOMs.
In the first post Stephen wrote to complete the build "2. 2 x 10uF 1206 Caps.", but both BOMs (Bom_TF536.csv and Bom_TF536_Buffered.csv) there are 10x 10uF 1206 Caps ?! Should be two to complete populated boards ?
Just use the cap dice

Sorry to annoy again, i'm ging through the Full BOM...something is wrong here. Text says all 10k ? Can someone please point me to the correct digikey part numbers please?

You're looking at the wrong column. Just look at value and ignore device. Value is the left of the ones there and is correct.
Device is the package i used to get the footprint. not the value. Its not editable in eagle.

Ok thanks. So:
RN1, RN2, RN3, RN4 are all "RES ARRAY 4 RES 2.2K OHM 1206" (digikey CAY16-222J4LFCT-ND) ?
RN5, RN6, RN7, RN8, RN9, RN10 are all zero ohm (bridge instead of buffer as i know)? .... i can't find the part on digikey, there are so many similar ones :?

0 Ohm RNs im using are here:
https://www.digikey.de/products/de?keywords=Y9000CT-ND
You need them
only if IDE is unbuffered, otherwise left unpopulated!
RN1, RN4 - 4k7
RN2, RN3 - 2k2
PS
if someone want to sell his unpopulated boards - please PN me, im out of boards...

Thanks 8 Bit Dreams !
Are you sure? Full BOM says RN1, RN4 = 2K2 !
Value RN2, RN3 is missing in the full BOM.

Ok, if this as you say is correct:
RN1, RN4 - 4k7
RN2, RN3 - 2k2
...the full BOM here in post 1 from steven is definitely wrong.
On the populated boards RN1-RN4 have all "222" printed on them ....so should be the same :?:
Steven, can you check this please?
