WAT-910BD H/W MANUAL
The pin arrangement and the outline circuit diagram of each pin are shown below.
All pins of J7 connector are directly wired to Camera DSP through the bead.
(EMI231-234, inductor for high frequency.3.3[V], CMOS logic input/output. There are no buffers/drivers.)
And the varistor elements are connected between each terminal and camera GND as countermeasure for the
electrostatic discharge and/or surge damage.
Each pin is connected to 3.3V(internal camera circuit) through resistors (4.7k ohm).
