B.4.1 Adding Other Components
There are pads that can be used for surface-mount prototyping involving SOIC devices.
There is provision for seven 16-pin devices (six on one side, one on the other side). There
are 10 sets of pads that can be used for 3- to 6-pin SOT23 packages. There are also pads
that can be used for SMT resistors and capacitors in an 0805 SMT package. Each compo-
nent has every one of its pin pads connected to a hole in which a 30 AWG wire can be sol-
dered (standard wire wrap wire can be soldered in for point-to-point wiring on the
Prototyping Board). Because the traces are very thin, carefully determine which set of
holes is connected to which surface-mount pad.
B.4.2 Measuring Current Draw
The Prototyping Board has a current-measurement feature available on header JP1. Nor-
mally, a jumper connects pins 1–2 and pins 5–6 on header JP1, which provide jumper con-
nections for the +5 V and the +3.3 V regulated voltages respectively. You may remove a
jumper and place an ammeter across the pins instead, as shown in the example in
Figure B-5, to measure the current being drawn.
