PPC-A9-121-C¶
Version 1.1
Product Overview¶
The Cortex®-A9 series PPC-A9-121-C (PN: CS10768F121) is a rugged, high-quality industrial panel PC. It features a 12” multi-point capacitive touch screen with a resolution of 1024 x 768 pixels.
The PPC-A9-121-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.

UART can be swapped between RS232 and RS485 modes easily, so if you need different RS232/RS485 configuration, please get in touch with the Chipsee Technical Support at support@chipsee.com
Power Input¶
The PPC-A9-121-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.
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-A9-121-C 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 float 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-A9-121-C Power Input connector (pin 3) is properly connected to the Power System Ground to provide sufficient EMI shielding and eliminate the problem entirely.
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.
Connectivity¶
There are many connectivity options available on the PPC-A9-121-C industrial PC. It has 4 x USB 2.0 HOST, 1 x USB OTG (can be customized to Host or OTG), 1 x Channel 1000Mbps LAN (RJ45) Ethernet connector supporting up to 1 Gbps, and 4 x DB9 connectors.
DB9 Connectors¶
The PPC-A9-121-C Industrial Panel PC has 4 x DB9 connectors that are configured as RS232 by default as shown on the figure below. You can configure COM3/COM4 as RS485. If you need different RS232/RS485 configuration, contact the Chipsee Technical Support at support@chipsee.com.
USB Connectors¶
There are 4 x Type A USB HOST connectors onboard, as shown on the figure below.
There is also 1 x Type Mini B USB OTG connector, configured as slave by default.
LAN Connectors¶
LAN (RJ45) connector provides Ethernet connectivity over standardized Ethernet cables as shown the figure below. The integrated Ethernet interface supports up to 1 Gbps data throughput.
Note
Use CAT5 or better cables to achieve full data throughput over maximum distance defined by the 1000BASE-T standard (100m).
