Grove Voltage Divider

Grove Voltage Divider: for accurately determining a voltage from elsewhere

The Grove Voltage Divider offers two functions:

• It can divide an input voltage by 3 or by 10, by simply selecting 3 or 10 with the switch
• It can determine the level of an analogue voltage to within 1% (or less): from 0.3 to 12.9 Vdc (divided by 3); or from 1 to 43 Vdc (divided by 10)

A Grove module, therefore it easy to connect

This Grove module will connect very simply to your Arduino or Seeeduino microcontroller. First connect the external voltage source to port J1, and connect your voltage divider to port A0 of the Base Shied with a universal Grove cable. Then connect your Base Shield to the microcontroller. The resources provided below contain links to all the files you’ll need to use or develop your module.
