Install all of the lettered capacitors shown below (CC, CM, etc.). After inserting each capacitor, bend
its leads slightly to hold it in place. Limit soldering time to 2 or 3 seconds per lead, using a minimum
amount of solder to avoid ground shorts.
__CC and __CM (27 pF, "27" or "270")
__CG and __CH (39 pF, "39" or "390")
__CE and __ CK (39 pF, "39" or "390")
__CA and __ CP (39 pF, "39" or "390")
__CF and __ CJ (100 pF, "101")
Install short wire jumpers at CD and CL. Use discarded component leads to form the jumpers. Do not
leave any excess lead length above the board.
Capacitors CB and CN are not used and should be left open.
Install the 0.1 µF capacitors ("104") with 0.1" (2.5 mm) lead spacing.
__C4 (near X1) __C13 (near X7)
Install the 0.1 µF capacitors ("104") with 0.2" (5 mm) lead spacing.
__C15 __C18 __C27 __C32 __C46
Install the .01 µF capacitors ("103") with 0.1" (2.5 mm) lead spacing (C1-C3, etc.). Use the Parts
Placement Drawing to verify the reference designators on capacitors in the crystal filter area that are not
labeled.
__C1 __C2 __C3 __C5 __C6
__C7 __C8 __C9 __C10 __C11
__C12 __C16 __C17 __C19 __C21
__C22 __C24 __C26 __C33 __C35
__C39 __C40 __C41 __C42 __C43
__C44
Note: You'll have one .01 µF capacitor of this type left, which has been included as a spare.
Install C37 (.001 µF, "102"), which is near the microcontroller, U1.
