uFreq V2.0 is fairly close to V1.0 in function, However it moves the potentiometers to through hole parts (could be reverted to surface mount with an adapter, or some creative soldering,) as well as adds an additional output that produces one voltage glitch per cycle, great for a sync out. Additionally, the pin configuration has been made a bit more breadboard friendly. As a final touch, usage of the LED is now no longer exclusive to having a full 5v output signal.
