ATM…
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-A55-070 Industrial Panel PC is based around the powerful RK3568 System on Chip
(SoC), powered by the Rockchip RK3568 low-power processor which integrates a quad-core
Cortex -A55 processor.
The RK3568 supports multi-format video decoders and has a high-performance RAM
(LPDDR4X) capable of sustaining demanding memory bandwidths. It also provides a
complete set of peripheral interfaces.

Power Input
The PPC-A55-070 Industrial Panel PC can be powered by a wide range of input voltages:
From 6V to 36V DC. The power input connector is a 3-pin, 3.81mm terminal. The polarity
and the pinout is clearly marked on the housing of the product as shown on the gure
below. There is one power input connector which is a 2.1mm I.D x 5.5mm O.D x 9.5mm DC
connector. For a proper DC power adapter, refer to the gure below.

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-A55-070 Industrial Panel PC uses a 5-point capacitive touch screen.

Note
The system ground “G” is connected to power negative “-” on board.
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-A55-070 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.
