On my BOM (1010_HERMES_PROD_BOM_08112012.xls) C37 is listed as a<br>
33pf and there is only ONE instance of it. There is no C70,
C228, nor C229 on<br>
my BOM as mentioned however item 15 is a 47nf cap not 1nf on my
BOM.<br>
<br>
So I'm not sure what I need to do for the correct values of C70,
C228 and C229?<br>

Also, dealing with the fuses, on my BOM F1, F2, and F3 are all 2
amp fuses, where<br>
Stijn mentions all 3 of his are different. Are the 2 amp fuses
OK to use?<br>

It appears the BOM and Schematic needs to be updated. Am I
missing any other changes?<br>

Hi Rick,<br>
<br>
Not sure I see anything wrong with the Item 15, C150 line you
listed.<br>
<br>
Here is my notes (I could be wrong) on the referenced BOM:<br>
<br>
Item 9: added C70 1nF from schematic value (Abhi says it is
100nF), looks like 1nF cap on TAPR build<br>
Item 10: C37 not on board, C39 is dup item 8 on line 44<br>
Item 18: Part Number 08055C473KAT2A should be 474<br>
Item 19: Digikey part is 10V, OK for all but C194 is on 12Vbus so
need 16V or higher.<br>
Item 32: Part number RLP-50+ should be 40+<br>
Item 92: Part number CRCW080512K0FKEA should be 63.4K<br>
Item 101: Digikey M25P16-VMN6TPCT-ND should be VMW, PCB Footprint
SOIC-8 should be SO8W<br>
Item 122: Part number LT3680EDD#PBF shoud be LT3680EMSE#PBF, PCB
Footprint DFN (UPDATED) should be MSOP8<br>
<br>
Still working on my soldering of my build. Having better luck when
tinning both board and device pads for U13, 58, 10, 11, 12, and 21.<br>
Everything else OK with handsoldering. Might need to reflow U23
again.<br>
