7.3.7

Signal Connector J7

Signal connector J7 contains the ports PTA and PTB, and the output of the Hall sensor supply regulator. Supply 
voltage, VDDX regulator output (+5.0 V), analog and main supply ground are connected as well. Physically, the 
connector J7 has 2 rows of pins, with 0.1” pitch.

7.3.8

Signal Connector J8

The J8 connector is header type 2x2, 0.1” (2.54 mm) pitch.
