20 Feb 2009 : New stock design changes : Added SOT-23 regulator position. Added second power jack for when PCB is cut in two. Added 3.5mm terminal block. Removed 2.5mm pitch row.
Oops! the new boards have the top groundplane missing due to a mess-up with the PCB artwork. They are still perfectly useable as the ground tracks are interconnected by tracks on the underside. The grounding can be improved if necessary by linking the ends of the vertical ground traces to one of the top power tracks to form a grid. The top-left power jack outer tag is unconnected, but can easily be solder-blobbed to the adjacent pad which is brought out on a couple of holes. As a result the price has been reduced to two for £15 or five for £30

Solder resist reduces risk of solder shorts.
1mm hole size allows fitting of 0.1" pin headers etc.
Rohs compliant Gold plated finish for good solderability and long shelf life
Overall perforated groundplane for good high-speed signal integrity
Underside track connectivity indicated by printed lines on top side silkscreen.
Silkscreen block areas for writing pin legends, serial numbers etc.
Hole grid allows snapping into multiple smaller sections
Through-hole area
Dense through-hole pattern with groups of 3 interconnected pads for high density DIP
layouts.
Uncommitted power/common clock rails can be linked as required.
SMD areas
Central 0.05" (1.27mm) area for SOICs, SOT-23 discretes etc, with 2 through-hole pads
per SMD pin for interconnection.
2 power (or clock) and 1 ground rail runs down each side of SMD area for quick & easy
hookup.
Fine-pitch SMD breakouts on underside for pitches of 0.5mm, 0.65mm. 0.8mm and 1.0mm for
ICs, FFC connectors, small discretes (e.g. SOT-323) etc

3.5mm terminal block
Plated-through slot holes for 2.1mm or 2.5mm DC power jack. (Two provided - useful if PCB
is cut in two)
3x34 row 0.1" connector position with breakout pads, for DIN41612, 2-row IDC
connectors or 3 row 0.1" headers etc.
