Schematic
The schematic of the board is shown in Figure 3. The S-VM1010-C Eval PCB consists of
the VM1010 microphone a configurable threshold resistor circuit, current sense chip
and a 0.1uF power supply bypass capacitor along with an edge connector. There are
solder jumper options for Rg Gain Adjust Circuit (S1, S2) and for Current Sense circuit
enable (SCS).
