Hi All,

For those making their own Hermes cards, please note corrections below,

Hermes BOM Corrections:

1. R102 & R145 are shown under item 4, 10nF Capacitor. I suspect this is
intentional, but just want to check it's not a typo?
R102, R145 are bypass resistors in case you do not want to use SW1, if
using SW1 they can either
be populated by 10nf caps or left unpopulated

2. Item 18 is shown as a 47uF capacitor, but the Digikey part number is for
a 0.047uF capacitor. Should this show 47nF?
C185 was changed to a lower value for high frequency suppression

3. Item 54 is shown as LFCV-52+ in one column, but a LFCN-80+ in another
column. Which is the correct part?
This filter was changed to the LFCV-52+

4. Item 78 shows a value of '220E', the part number is for a 180R resistor.
220E is the correct value

5. Item 92 is shown as a 63.4K resistor, the digikey part number in the
last column is 63.4K, but the part number in the first column is 12K.
63.4K is the correct value

Corrections pointed out by Mike:

line, item, comment, correction
48, 10,  "R126,R146",  "C126,C146"
58, 19, no digikey #, 587-1295-1-ND
104, 54,  535-10442-1-ND is 0402 size,  535-10493-1-ND is 0805 size
