ARIABLE VOLTAGE
The Joy-Pi Advanced also offers the option of a variable voltage supply. Hereby a voltage of 2 - 11 V
with up to 1 A can be retrieved. To activate the variable voltage, set the Connection to Voltmeter
switch to ON and the Voltmeter switch to ON as well. The desired voltage can now be set via the
rotary potentiometer. The actual voltage is also displayed on the voltmeter. The voltage can then
be taken via the 2-pin connector on the voltmeter.

OLTMETER
As an alternative to the variable voltage supply, the voltmeter can also be used individually. Thus,
voltages of up to 30 V (DC) can be measured here. To use the voltmeter, first set the switch of the
variable voltage supply to OFF. Then set the switch of the voltmeter to ON. Now the voltage to be
measured can be connected to the 2-pin header of the voltmeter or to the VAR connections above
the breadboard. The measured voltage is then shown on the display of the voltmeter.
A
NALOG DIGITAL CONVERTER
All channels of the analog-digital converter, which can be used for voltages of up to 5 V, are led out.
This has a total of eight channels, of which the first six channels are used for the installed sensors.
The last two channels are not assigned and can be used freely. But also the other six channels can
be used freely if required. To do this, simply remove the jumper of the desired channel and connect
the analog signal to be measured to one of the channel inputs. For potential equalization with an
external circuit, the GND connection can be used here. Note, however, that the ground connections
are interconnected at this point. Therefore, voltages with different reference potentials cannot be
measured simultaneously.

OLTAGE TRANSLATOR
Above the analog-digital converter there is also the voltage conversion. Here you can upscale up to
2 signals with 3.3 V to 5 V and downscale up to 3 signals with 5 V to 3.3 V.
