Evaluation Board
The Evaluation Board, see
, acts as an interface between one TLI4970 and one PGSISI-2. The objective
of the Evaluation Board is to electrically connect the sensor with the 25 pin D-Sub (DB25) connector of the PGSISI-
2.
The following chapter describes the functionality of the hardware. The layout and the schematic of the Evaluation
Board are shown in
and
respectively.
