Prototyping area

A prototyping area has been implemented in order to perform small additional

configurations.

It allows the user to connect an expansion board, components on input and output, and a

divider bridge for a 5 V to 3.3 V conversion, as shown on the following figure.

Figure 11. Prototyping area

Note also that the supply voltage of the operational amplifier can be either external or based

on the internal 3.3 V. If a high output voltage and thus a higher power supply voltage is
