Add R18 and R19. Calculate R18 and R19 using the
following equation:
V = 1.0 V (1 + R18/R19) + R18

Default Jumpers
The default jumper settings are shown in Figure 12. Both DVDD
and AVDD are powered by 3.3 V from the Arduino shield (JP2
and JP3 in Position C).
JP1 controls the reset signal and has two jumpers in Position A
and Position C, respectively. Position A connects the
reset pin to the reset button. Position C connects the
reset pin to a general purpose input/output (GPIO) on
the ADuCM3029 microcontroller.

The AD5940-BioElectric
bioimpedance and biopotential measurements. The board
contains the AD8233 heart rate monitor, isolation capacitors
and limit resistors necessary for bioelectric measurements. For
further details, refer to AN-1557 in the Application Notes
folder.

amperometric, and potentiostat measurements. The board
AD5940 contains two resistor capacitor (RC) networks (Test 1 and Test 2) to
AD5940 verify measurement sequences. There is also a USB connector
that provides an option to connect custom cable to the board. By
default the board is configured to measure Test 1. Details on the
supported measurements can be found in AN-1563.
