Temperature Sensor
A surface-mount, NTC Thermistor is installed at location RZ1. This component provides a
voltage input to the MCU inversely proportional to temperature. The component used provides
a B = 3900. Refer to Table 3 below.
User Signals
Table 3 shows the connections for each user I/O device.
Table 3: User I/O
User Enable
The User option header block enables or disables each User I/O device individually. User I/O
includes 4 green LEDs, 2 push button switches, one 4-position DIP switch, a Light Sensor, and
