3. Using the Internal 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 2.17 shows an external view of the OSC-2 oscillator circuit bare board and the connector pin locations. Figure 2.18
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
