Anelok: BOM updated for 201501

First of all, I made some small changes to the schematics. It's
mainly explanations, but I've also relaxed the capacitance
requirements on the 32.768 kHz crystal:

Then I updated the BOM information. An example for an order quantity
of ten part sets is at the bottom of this mail. A new feature of this
BOM is that it uses the component references instead of groups. The
groups were more confusing than helpful since many parts appear in
multiple groups and the assignment then looked rather arbitrary.
This should now be usable for anyone interested in making boards of
the 2014 / 201501 version of Anelok. A daring soul may also try the
following substitutions:
- defy the oppressive standardization of the USB-IF and use a Micro B
connector instead of Micro AB. ZX62R-B-5P or similar should work
nicely. The "R" is important - even though the connector is mounted
below the PCB it uses the "reverse" or "top mount" layout.
Benefits:
- connector is more solid
Disadvantages:
- some 10% more expensive (surprisingly)
- host role detection (ID pin grounded) only works with a
non-standard cable, e.g., the Y-cable Changchang described.
- boldly go where I haven't ventured yet and replace 0 R resistors
R20 and R21 with beads, e.g., Samsung CIM05U601NC or Taiyo Yuden
BK1005HS601-T
Benefits:
- should keep EMI and ESD out
Disadvantages:
- may make the capacitive slider work less well
- omit the varistors.
Benefits:
- less soldering work
- fewer things to buy
Disadvantages:
- no ESD protection (for "lab" use that shouldn't be a major
concern)
As usual, the shopping list below shows the order quantities that
yield the best prices. They may therefore be larger than what would
be needed to make 10 units.
