Version 1.1

Product Overview

The Cortex®-A9 series PPC-A9-190-C (PN: CS14900F190) is a rugged, high-quality industrial panel PC. It features a 19” multi-point capacitive touch screen with a resolution of 1440 x 900 pixels.

The PPC-A9-190-C Industrial Panel PC is based around the powerful CS-SOM-iMX6Q System on Module (SoM), powered by the i.MX6Q Arm® Cortex®-A9 quad-core Application Processor (APU). The i.MX6Q APU represents the latest achievement in integrated multimedia applications processors, delivering high-performance computing, an abundance of integrated peripherals, and high power efficiency.

This product also features a broad range of connectivity options, providing a high level of scalability for various use cases. It is the perfect solution for power-constrained applications on the Edge, acting as a robust control unit for collecting, processing, and aggregating field data. The i.MX6Q APU is part of NXP’s EdgeVerse™ edge computing platform.

The NXP i.MX6UL APU does not generate extensive heat, so even the thin aluminum housing on PPC version delivers sufficient thermal dissipation. With its junction temperature from -40 to +125°C, the APU itself is well suited for extended temperature range in both automotive and factory environments.

Power Input

The PPC-A9-190-C Industrial Panel PC can be powered by a wide range of input voltages: From 15V 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 figure below.

Touch Screen

The PPC-A9-190-C Industrial Panel PC uses a 10-point capacitive touch screen.


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 float erratically across the display. There are several solutions to this problem:

  1. Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.

  2. Make sure that the PPC-A9-190-C Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.

  3. Bad GND problem can also be confirmed 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.


There are many connectivity options available on the PPC-A9-190-C industrial PC. It has 2 x HOST USB Type A connectors, 1 x USB OTG Type Mini B, 2 x network connector (RJ45) supporting up to 1 Gbps, and 5 x UART terminals (RS232/485). This device also features two CAN interfaces.


The serial communication interfaces (RS485, RS232, and CAN) are routed to a 16-pin 3.81mm terminal, as illustrated in the figure below. Serial communication on both RS485 and RS232 interfaces can reach up to 115200 kbps.
