The PPC-A9-121-U-C (PN CS10768F121P-U-C) is a high-quality industrial panel computer, that features a 12.1-inch LCD with capacitive touchscreen, a quad-core Cortex-A9 processor with 2GB DDR3 RAM and 8GB eMMC Flash, an onboard WiFi and Bluetooth, 1 LAN Ethernet, 2 USB 2.0 ports,1 USB OTG ports, 4 RS232 ports, 1 HDMI port for a secondary monitor, and a 3.5mm audio connector.

Hardware Features

The PPC-A9-121-U-C has several expansion connectors on the backside – 2 USB 2.0 connectors, 1 USB OTG connector, 1 LAN connector, and 4 RS232 connectors by default (can be customized to 2*RS232+2*RS485). It also features a WiFi and Bluetooth antenna, an HDMI connector, and a 3.5mm audio connector. It also features a fingerprint module (Zaz-070S).

The WiFi/Bluetooth module is based on the Realtek RTL8723BS an 802.11bgn 2.4G single-chip that integrates Wireless LAN (WLAN) and an SDIO interface controller with an integrated Bluetooth 2.1/3.0/4.0 controller. It combines a WLAN MAC, a 1T1R capable WLAN baseband, and WLAN RF in a single chip.

Please note that a 4G/LTE module can be added, simply use the check box when you’re ordering to add it.

This computer has 5 UART channels. One UART channel is used by Bluetooth, the remaining 4 are routed to the 4 DB9 ports (COM1-4); It has 4*RS232 by default and can be customized to 2*RS232+2*RS485, but it is possible to configure each port individually as RS232, RS485, CAN. Please contact us if you require a different configuration.

The speed of the RS232 port is up to 115200 Baud.

The PPC-A9-121-U-C has one channel 1Gb Ethernet port, and one HDMI port which can be configured by software. The maximum resolution supported on the external HDMI monitor is 1920×1080 at 60Hz.

When it comes to audio capabilities, the PPC-A9-121-U-C has one 3.5mm Output/input connector and a 2W internal speaker.

Display and Touch Screen

The PPC-A9-121-U-C features a 12.1’’ display with a 1024×768 pixel resolution and a 10-point capacitive touch screen. 10-point capacitive touchscreens offer a stable and accurate control over the device, as well as great image clarity.

The screen offers very high brightness of 350 nits. When it comes to the viewing angle, the screen offers various angles: top, bottom, left, and right view.

If your application requires a secondary display the HDMI port on the back of the panel allows the device to work in a double monitor configuration up to 1920×1080 pixel resolution at a 60Hz refresh rate.

Performances and reliability

This System-on-Module makes it possible to integrate a whole computer into a device, significantly simplifying the customization of the device. This is why we are able to offer fast turnaround customization of all our products.

At the core of each Chipsee product lies a System-on-Module. This means all the products share the same core. It makes your application easily upgradable – without needing to rewrite a single line of code your application is upgraded, thanks to the same System-on-Module.

This product features the .iMX 6 series of application processors, the CS-SOM-iMX6Q.

The .iMX6Q Quad processor represents the latest achievement in integrated multimedia applications processors. They feature advanced implementation of the quad Arm® Cortex®-A9 core, which operates at speeds up to 1 GHz. They include 2D and 3D graphics processors, 1080p video processing, and integrated power management. Each processor provides a 64-bit DDR3/DDR3L/LPDDR2 memory interface and a number of other interfaces for connecting peripherals, such as WLAN, Bluetooth®, GPS, hard drive, displays, and camera sensors.

Contact us for further details if you want to buy the CS-SOM-iMX6Q separately.
