3) Using the Oscillator Circuit Bare Board
To use this product at a frequency you like, build a desired oscillator circuit on the included OSC-2 oscillator circuit
bare board. Figure 2.19 shows an external view of the OSC-2 oscillator circuit bare board and the connector pin
locations. Figure 2.20 shows the circuitry of the oscillator circuit bare board OSC-2. Use the number of oscillator
circuits recommended by the oscillator manufacturer.
J1-4: GND
J1-3: Oscillation output
J1-2: GND
J1-1: VCC
