1.2

External Power

When using external power, set the S5 switch to the top position (External). Apply the external supply
voltage to the J33 header (see

Figure 3

). For lowest power consumption, open all jumpers on J1, J2, and

J3. If the circuit does not use a regulator (which is optional), the operational supply voltage range is 1.8 V
to 3.6 V. If communicating through USB, set GND on J2 and the communication jumpers on J1.
