Cat Shark User Guide
Description
The ISL29501-CS-EVKIT1Z is a distance measurement
reference design consisting of an optical board and a
controller board. It combines the
OSRAM SFH 4550 IR emitting LED and OSRAM SFH 213FA
photo-diode. The two circuit boards are connected together
with a flat flex cable. Included is a USB flash drive containing
the evaluation software for a PC and related technical
documents.
The ISL29501-CS-EVKIT1Z kit also allows quick evaluation of
the ISL29501 performance for a 2m sensing system.
