PPC-A55-101 Product Overview
Chipsee IPC Page 4 of 18

The PPC-A55-101 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.

1(1,2)This product has 4 x UART by default, 6 x UART channels at most. The default conguration is 2 x RS232 and 2
x RS485, including 1 RS232 debug port. The 2 x CAN can be congured to RS232. UART can be swapped
between RS232 and RS485 modes easily, if you need a dierent RS232/RS485 conguration, please get in touch
with the Chipsee Technical Support at [email protected]
Power Input
The PPC-A55-101 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. The polarity
and the pinout is clearly marked on the housing of the product as shown in the gure
below.
Power Input
Note that the “+” sign represents the positive power input, it is printed 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-A55-101 Industrial Panel PC uses a 10-point capacitive touch screen. However, the
Debian OS supports only One-Point touch.
The gure below shows the capacitive touch screen connected to the motherboard via the
USB connector.

Connectivity
There are many connectivity options available on the PPC-A55-101 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, 2 x CAN and 4 x UART terminals (RS232/485).
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-A55-101 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.
