SCHEMATIC
VCNL4000 Board Layout
The sensor board includes the VCNL4000 sensor and a
470nF capacitor. It is connected to the common 3.3 V power
supply used for the infrared emitter on Pin1 and the
ASIC_V DD on Pin7. As is shown in Figure 3, large areas of the
top side are ground plane to avoid ESD problems when
handling the board. The odd-numbered pins are on top side
and the even-numbered on the bottom side

VCNL4010 and VCNL4020 Board Layout
The VCNL4010 and VCNL4020 sensor boards, Figure 4 and
5, have test points to allow simple evaluation and/or
connection to the customer’s application board. The boards
also include an external emitter (VSMF2890GX01) to
increase the measurement range to 500 mm and supporting
FET’s to use the integrated emitter, the external emitter or
both in series.
Schematic
Only 4 wires are needed to connect to VCNL40x0:
? SDA (J1) and SCL (J3) need to be connected to the
microcontroller
? V DD (J11) needs to be connected to the power supply
? Ground pin (J2/J15) needs to be connected to the
application ground plane.
See Figure 6, 7, and 8.
