External input signal connections to drive the LED Emulator.
External output signal connections.
Jumper when installed used to accommodate common-anode drive.
Jumper when installed used to accommodate common-cathode drive.
Jumper used to connect external pull-up resistor R4 (Si87xx open-collector output only).
Jumper used to tie the enable pin to VDD and activate the output default state (Hi-z, logic-low, or
logic-high).
4.1. Voltage and Current Sense Test Points
The Si871x evaluation board has several test points. These test points correspond to the respective pins on the
Si871x integrated circuits as well as other useful inspection points. See Figures 6 through 8 for a silkscreen
overview. See schematics in Figures 9 through 11 for more details.
