4.2.1.1 Connector 1
Connectors J1 through J5 all have digital I/O, power routing, ground and +K (external power) options. But
the range of choices is greater in the digital I/O options for J1 through J3 because the pins are connected to
two-transistor cells as opposed to the one-transistor cells of J4 and J5.
Connectors J3 and J4 add the ability to be configured as analog inputs.
If the LCD option is selected, it will populate the 8 available pins of J1.
Figure 4-3 Pinout Options for J1
4.2.1.2 Connector 2
The two DAC channels and the PWM outputs are available on J2. The 0-10 V option requires an external
+12 V power supply connected to +K on J2.
