Description: This PCB is based on Ben Eater's CPU Clock module breadboard design but only the astable portion.
Features: - Output is 1Hz to 500Hz with a 1uF electrolytic capacitor (227kHz with a 1nF cap) - Synchronized LED flashes are via the CLOCK or CLOCK output connectors - 2-pin socket so you can switch out capacitors for more speed - 5v output connector was added in v1.2 to also power the device under test - 3mm (0.14") mounting holes
Power Input: - Power In is from a diode-protected 5v 2-wire connector or miniUSB but not both
