It is available both as an embedded solution and as a device hosed in an aluminum casing
with bezels, thus facilitating dierent installation options:
Installation on an industrial cabinet
Integration with the existing equipment
The PPC-A72-236 Industrial Panel PC is based around the powerful CS-SOM-RK3399 System
on Module (SoM), powered by the Rockchip RK3399 low-power processor which integrates a
dual-core Cortex -A72 and a quad-core Cortex -A53 with a separate NEON coprocessor.
The RK3399 supports multi-format video decoders and has a high-performance dual-
channel external memory interface (DDR3/DDR3L/LPDDR3/LPDDR4) capable of sustaining
demanding memory bandwidths. It also provides a complete set of peripheral interfaces.

Power Input
The PPC-A72-236 Industrial Panel PC can be powered by a wide range of input voltages:
From 12V to 36V DC. The power input connector is a 3-pin, 3.81mm terminal.
Power Input
Note that the “+” sign represents the positive power input, and it is printed both at the
casing and as a silk-screen on a PCB of the embedded version. The “-” terminal is shorted to
the ground.

Attention
A capacitive touch screen is susceptible to power noise and Electromagnetic Radiation (EMR). It may cause LCD ripples
or even capacitive touch malfunction. If using a capacitive multi-touch test application, you might notice the touch
points oat erratically across the display. There are several solutions to this problem:
Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.
Make sure that the PPC-A72-236 Power Input connector (pin 3) is properly connected to the Power System
Ground to provide sucient EMI shielding and eliminate the problem entirely.
Bad GND problems can also be conrmed by touching pin 3 of the Power Input connector with one hand while
operating the capacitive touch screen with the other hand. In this case, the operator’s body acts as the Power
System Ground.
