Figure 22. 3v Temporary 100 Ohm Load Resistor Connected to Bottom of Board

The 9v battery clip is not supplied. This is a low current, temporary power connection that is used to
protect the board in case of a problem.
The temporary 3v 100 ohm load resistor will stay connected until the main is has enough circuitry to
keep the switching supply in regulation.
