ADDITIONAL EVALUATION BOARDS
HIGH POWER LED DAUGHTERBOARD
The ADUX1020-EVALZ-LED is an optional daughterboard for
the standard ADUX1020-EVAL-MCM evaluation board. It
functions as a high-power LED driver intended for gesture
recognition at distances greater than 15 cm.
To use the ADUX1020-EVALZ-LED, attach it to the ADUX1020-
EVAL-MCM evaluation board as shown in Figure 9. The daughter-
board connects to the ADUX1020-EVAL-MCM via five pins,
labeled on the daughterboard as GND, GND1, LEDX, 3.3V, and
VLED. These pins on the daughterboard plug into five similarly
spaced test points on the ADUX1020-EVAL-MCM labeled JL1,
JL2, JL3, JL4, and JL5. When connecting the ADUX1020-
EVALZ-LED, ensure Header J7 on the ADUX1020-EVAL-
MCM is not connected, as shown in Figure 9.
Operation and configuration of the ADUX1020-EVAL-SDP with
the ADUX1020-EVALZ-LED daughterboard follows the
instructions instructions listed in the Evaluation Board
Software Quick Start Procedures section.
