5.6 Temperature
sensor
There is an analog temperature sensor (STLM20) available on the board that is connected
to the analog input AIN0 of the CPU board. It is possible to disconnect it by removing jumper
JP10. The jumper is loaded by default.
5.7 Potentiometer
There is a 10 k
Ω
potentiometer available on the board connected to the analog input AIN1 of
the CPU board. It is possible to disconnect it by removing jumper JP9. The jumper is loaded
by default.
5.8
General-purpose ADC connector
Eight analog input lines are available on connector CN9. Inside the connector it is also
possible to determine the range of the conversion by setting the conversion limits on the pin
CN9-19 (lower limit) and CN9-1 (upper limit) via jumpers JP7 and JP8.

Jumper
Description
Configuration
JP14
Can be used to disconnect the +5 V delivered from the DC/DC
converter U16 (Default - loaded).
JP15
(SMD
resistor)
(1)
1. The configuration of this JP is done loading a 0 ohm resistance between two different positions.
For L7986A the jumper must be set (Default).
Optional when L5973A would be assembled, the jumper must
be set as shown at right.
