How does the board operate?
When the voltage signal is supplied on either of the input channels, the additional board starts to convert the analog signal into digital one.
The analog voltage signal is first amplified using the operational amplifier (MCP6284), then it is sent to the A/D convertor (MCP3204),
Figure 4. As already mentioned, the converted voltage signal is sent to a microcontroller via the Serial Peripheral Interface (SPI).
