4.1. Voltage and Current Sense Test Points
The Si826x evaluation board has several test points. These test points correspond to the respective pins on the
Si826x integrated circuits as well as other useful inspection points. See Figures 7 through 10 for a silkscreen
overview. See schematics in Figures 11 through 14 for more details as well.
