TinyCLOCK Breadboard Module

I was tired of constantly building the same clock circuit on a breadboard, so I finally decided to design a small PCB.

Instead of soldering the crystal directly to the board 2 female headers can be used, so it can be easily changed with one of a different frequency.

The pinout is super simple, just 4 pins:

VCC (5V) and GND for power

CLK1 is the main clock output

CLK2 is a slightly delayed clock output (useful for some old CPUs or microcontrollers)

The delay of CLK2 depends on the value of C4, 47pF should give a delay of about 5ns
