EPC/PPC-A7-070HB-C

Version 1.0

Product Overview

The Cortex®-A7 series EPC/PPC-A7-070HB-C (PN: CS10600U070) is a rugged, high-quality industrial panel PC. It features a 7.0” multi-point capacitive touch screen with a resolution of 1024 x 600 pixels.

It is available both as an embedded solution and as a device hosed in an aluminum casing with bezels, thus facilitating different installation options:

  • Installation on an industrial cabinet

  • Integration with the existing equipment

The EPC/PPC-A7-070HB-C Industrial Panel PC offers a very low power consumption, despite its high-speed processing capabilities. It is powered by the i.MX6UL Arm® Cortex®-A7, an ultra-low power Application Processor Unit (APU) from NXP, running at up to 528 MHz.

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 -20 to +140°C, the APU itself is well suited for extended temperature range in both automotive and factory environments.

This product has 5 x UART channels in total. The default configuration is 2 x RS232, 3 x RS485. 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 service@chipsee.com

Power Input

The EPC/PPC-A7-070HB-C Industrial Panel PC can be powered by a wide range of input voltages: from 6 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 PPC version, as well as on the PCB itself of the EPC version, as shown in Figure 1.

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.

Note

The system ground “G” is not connected to power negative “-” on board, we connect “-” and “G” by using one 10MR resistor and one 1000pF capacitor.

Touch Screen

The EPC/PPC-A7-070HB-C Industrial Panel PC uses a five-point multitouch capacitive screen. Figure 2 shows the capacitive screen connected to the motherboard via the FPC connector.

../../../../../_images/TS_CON1.png

Figure 335: Figure 2: Capacitive Screen Connector

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 multitouch 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 EPC/PPC-A7-070HB-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.

Connectivity

There are many connectivity options available on the EPC/PPC-A7-070HB-C industrial PC. It has 2 x HOST USB Type A connectors, 1 x network connector (RJ45) supporting up to 100 Mbps, and 5 x UART terminals (RS232/485). This device also features two CAN interfaces, and a set of opto-isolated GPIO pins for various purposes.

RS232/RS485/CAN

The serial communication interfaces (RS485, RS482, and CAN) are routed to a 16-pin 3.81mm terminal, as illustrated on Figure 3. Serial communication on both RS485 and RS422 interfaces can reach up to 115200 kbps.

WiFi & BT Module

The EPC/PPC-A7-070HB-C Industrial Panel PC does not include an embedded WiFi/BT module. However, it has an onboard footprint accommodating for easy installation of the popular Realtek RTL8723 WiFi/BT module that supports BT/BLE 4.0 (with backward compatibility), as well as 802.11bgn 2.4 GHz Wireless LAN (WLAN).

../../../../../_images/WiFi_BT_PCBF.png

The enclosed (PPC) variant of the product has a specially designed connector hole for a standard SMA connector, allowing an external WiFi antenna to be connected.

GPIO

The EPC/PPC-A7-070HB-C Industrial Panel PC features a 10-pin 3.81 mm terminal that provides 8 x opto-isolated GPIO pins, of which 4 x are output, and 4 x are input pins. The 10-pin terminal also includes an isolated PSU input in the range of 5 to 24 VDC. The exact pinout is given in Table 3, below.

The GPIO HIGH output level corresponds to the voltage connected at the Isolated Power Input, while the GPIO LOW output level corresponds to the isolated Ground Input. Each GPIO output can drive loads up to 500mA, enough to drive various applications directly, such as relays or solenoid valves.

If the isolation is not a requirement, it is possible to use a non-isolated PSU instead.
It is also possible to use the onboard 5V power supply: it can be re-routed to the Isolated Power Input pin by populating R292 and R293 PCB footprints with 0Ω resistors.
Note that in this case, the Isolated Power Input pin will become an output for the onboard 5V power supply.

TF Card Slot

The EPC/PPC-A7-070HB-C Industrial Panel PC features 1 x TF Card (micro SD) slot as illustrated in Figure 8. It can address up to 32GB of memory.

Audio Connectors

The EPC/PPC-A7-070HB-C Industrial Panel PC features some audio peripherals, as well. It has 1 x 3.5mm audio input jack and 1 x 3.5mm audio output jack.

On the embedded panel PC version, the pink connector is the audio input jack (line-in) and the blue connector is the audio output jack (line-out, typically around -10 dBV). On the enclosed panel PC version, both audio input and audio output are clearly marked (Figure 9)

../../../../../_images/Audio1.png

Boot DIP Switch

The EPC/PPC-A7-070HB-C Industrial Panel PC supports boot from SD card. If you want to reflash the Operating System (OS), you can use the TF card for that purpose, combined with the DIP switch settings (Figure 10).

There is no need to alter the DIP switch settings during regular operation. However, if you need to reinstall the OS, please refer to Table 4 below. Detailed information on how to re-flash the OS can be found in the Software Documentation.
