Step 3: Making Fast Printed Circuit Modules
The solid line perfboard is made of fiberglass so it is stable. It it predrilled and the copper cladding pre etched into parallel lines. First you solder in the main components. Then, all you need to do is cut the lines you don't need, and add wires wherever you need them.
Pic3 shows a 28x-2 Picaxe controller module. It has grounded resistors to keep its inputs from floating and headers to provide access to all it pins.
pic4 shows the bottom of the circuit board. The continuous copper traces are drilled out with a 1/8" drill bit or cut with a knife wherever a break is needed. 30 gauge magnet wire is used for jumpers to complete the circuit. With careful layout on a module, very few jumper wires are usually needed.
I usually color code the headers that go to power and the serial in and serial out programming pins.
