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-A72-121-P 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
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.
Touch Screen
The PPC-A72-121-P Industrial Panel PC uses a 10-point capacitive touch screen.

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.

Connectivity
There are many connectivity options available on the PPC-A72-121-P industrial PC. It has 1 x
USB 2.0 HOST, 1 x USB 3.0 HOST, 1 x USB Type-C, 1 x network connector (RJ45) supporting
up to 1 Gbps, 8 x GPIO and 5 x UART terminals (RS232/485).
RS232+RS485+CAN+GPIO Connector
The serial communication interfaces (RS485, RS232, and CAN) are routed to a 12-pin
3.81mm terminal, as illustrated in the gure below. Serial communication on both RS485
and RS232 interfaces can reach up to 115200 kbps.
Isolated GPIO reduced schematic
Make sure that the PPC-A72-121-P 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 problems 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.
