Hello Mike,<br>
<br>
I do agree on most of your points, except for item 101. SO8N is
the correct outline for the board, so DigiKey number
M25P16-VMN6TPCT-ND is correct and column D and E of the BOM are
incorrect. VMW is not going to fit.<br>

Hi Stijn,<br>
<br>
Yes, thanks for the correction. Made me run to my parts box and
check: luckily had ordered the VMN !!<br>
<br>
Thanks for all your inputs; they were all excellent. You saved me a
few more orders!!<br>

Looks like R113 is the LT3680 switching freq: 56K = 680KHz, 63.4K =
600KHz.<br>
Looks like R101, 107 set the TPA0202 gain (fb): 47K would give 4.7X
gain vs 10K values.<br>
Looks like R123 is the ALEX_ANT_TUNE Pull down so likely the 10K
would be better than 0; as you noted in schem and TAPR build.<br>
