This product features the Rockchip RK3399, an ARM dual Cortex-A72 (1.8GHz) plus Quad Cortex-A53 (1.4GHz) high performance and ultra-efficient processor that implements the ARM v8-A architecture.

The EPC-A72-101 (PN CS12800R101E) is a high-quality industrial embedded computer, that features a 10.1 inch LCD with a ten-point capacitive touchscreen, an ARM dual Cortex-A72 (1.8GHz) plus Quad Cortex-A53 (1.4GHz) processor with 4GB DDR3 RAM and 16GB eMMC Flash, 1Gb Ethernet, 2 USB 2.0 ports, 1 USB 3.0 port, 1 Type-C port, 1 LAN port, 5 RS232 connectors, and 2 RS485 connectors, as well as a 3.5mm audio connector.

Hardware Features

The EPC-A72-101 has several expansion connectors on the backside – 2 USB 2.0 connectors, 1 USB 3.0 connector, 1 Type-C connector, 1 LAN connector, 5 RS232 connectors, and 2 RS485 connectors. It also features a 3.5mm audio connector and a TF card slot.

The WiFi/Bluetooth module is based on the Realtek RTL8723BU an 802.11bgn 2.4G single-chip that integrates Wireless LAN (WLAN) and a network USB interface (USB 1.0/1.1/2.0 compatible) controller with 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.

The EPC-A72-101 has a 10.1’’ 10-point capacitive touch screen, with a 1200×800 resolution. 10-point capacitive touchscreens offer stable and accurate control over the device.

Capacitive touchscreens offer great image clarity. They are also very durable and resistant to environmental contaminants like dust and water. These types of screens work best with either a finger or a stylus with a conductive tip.

The RS485 and RS232 connectors are DB9 connectors (as you can see from the image).

The speed of the RS232 and the RS485 port is up to 115200 Baud.

The EPC-A72-101 has one channel 1Gb Ethernet port and one TF (uSD) card connector. This device supports a TF card up to 32GB.

When it comes to audio capabilities, the EPC-A72-101 has one 3.5mm Output/Input connector and a 2W internal speaker.

The typical power consumption is 7.5W.

If you need a more customized solution, we can design, manufacture, and deliver you a tailor-made industrial PC.

Performances and reliability

This product features the Rockchip RK3399, an ARM dual Cortex-A72 (1.8GHz) plus Quad Cortex-A53 (1.4GHz) high performance and ultra-efficient processor that implements the ARM v8-A architecture. The fast processing of Cortex-A72 is particularly suited to mobile applications. 

This processor supports the following features: advanced single instruction multiple data (SIMD) operations, floating-point operations, and optional cryptography extension.

Multiple OS choices

This product comes with a pre-installed OS of your choice. Please use the drop-down menu to choose the one you need, and we’ll pre-install it for you.

It supports the following operating systems:

  • Android 7.1
  • Buildroot Linux Qt 5.14
  • Debian 10

* Chipsee Linux is based on NXP Yocto framework that we have integrated with:

  1. A Chipsee Hardware Test Application.
  2. An initialization script for GPIO/Buzzer/Audio.
  3. Multiple libraries, such as the libQt5Sql to develop Qt application with SQL.
  4. Various packages, such as the ntfs-3g to use NTFS.

Chipsee software engineers have created all the drivers, so every hardware feature is readily available for any standard development tool. If your project requires an OS that is not on the list, please contact us, and we’ll make a customized version that suits your needs.
