5.6.3 User Potentiometer
A footprint for installation of a potentiometer and a recommended noise-bypass capacitor are provided on the
Target Board. The footprint was designed for installation of a Bourns P/N 3352T-1-103LF, or equivalent, as
the potentiometer, and a Samsung P/N CL10B104KB8NNNC, or similar, as the noise-bypass capacitor.
When the User Potentiometer is installed, copper jumper E36 must be closed to connect the User
Potentiometer to the MCU.
