It is available both as an embedded solution and as a device hosed in an aluminum casing
with bezels, thus facilitating dierent installation options:
Installation on an industrial cabinet
Integration with the existing equipment
The PPC-A72-150-C 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.

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-A72-150-C Power Input connector (pin 3) is properly connected to the Power System
Ground to provide sucient EMI shielding and eliminate the problem entirely.
Bad GND problem can also be conrmed 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.
