Two Transistor Oscillator, MiniPCB, 06B-03, Rev A1-01

I made a two transistor oscillator with a nearly 2 minute period!

The PCB is a two layer board, and designed to be easy to manufacture and assemble. And it is optimized for cost by being panelized on 100 x 100 mm squares.

Signals are routed on the bottom layer (the layer with the part number), and a common ground plane (as uncut as possible) is on the top layer.

The P1 connector is located in a standard position with respect to the board edges: making it possible to build a universal tester, backplane, or stand.

For ease, start with the shortest components.

For ease of changing between five-pin boards, use Interface Board, 00A-12.
