3 Board Layout

Figure 42 and Figure 43 show the board layout of the FDC1004EVM.

Sensor layout has been designed to demonstrate the possible trade-off between sensor sensitivity and protection from interferences. SHLD1 surrounds "LEFT" sensor and it has a bigger area than SHLD2 that surrounds "RIGHT" sensor. As a consequence, the "LEFT" sensor is better shielded from interferences but at the cost of lower sensitivity.
