1.4 Hardware installation
Figure 1 shows the location of the main components of the evaluation board. The schematic
drawing is given in Figure 6 .
Figure 1. Evaluation board layout
1.4.1 Power supply
The evaluation board is directly supplied by the USB Connector (bus powered) and
therefore does not require any external supply. In case the components added on the wire-
wrap area sink more than 500mA, an external power supply must be used.
1.4.2 Jumper settings
The W1 jumper selects the analog trimmer. When the jumper is removed, the analog
trimmer is disconnected from Ground in order to stop power consumption and to meet the
power specifications of USB suspend state. If analog-to-digital conversion is needed for
application development, you can replace this jumper by a switch transistor controlled by an
I/O pin.
