Figure 5-3. Signal Line Circuitry
These can be substituted for different resistors as desired. Additionally, there are pads for pull-up and pull-down
resistors to VDD and GND respectively. Add any 0603 resistor to the footprint shown as R17 to provide pull-up to
VDD, and add any 0603 resistor to the footprint shown as R29 to provide pull-down to GND.
Each signal line also includes two footprints that allow for the user to attach capacitors or other devices with
matching footprints. On the top side of the board, shown in
Figure 5-2 and Figure 5-3 as C5, a standard 1206
footprint exists between the U1 pin signal and the GND signal. The user can solder a capacitor to this footprint to
provide capacitance to the signal line.
Figure 5-4. Signal Line Circuitry Bottom Layer
On the back side of the board, shown in Figure 5-4 as C104, a standard 1812 footprint exists, also allowing for
connection of a capacitor between the U1 pin signal and GND. The user can solder a capacitor to this footprint to
provide capacitance to the signal line.
