conga-PA3 - Pico ITX with Intel® Atom™ E3800 and Celeron™


The ultra miniaturized conga-PA3 Pico ITX single board computers for professional use are based on the Intel Atom E3800 and Celeron series (codenamed Bay Trail) and are currently offered with the following CPU variants:

Intel® Atom™ E3826 (2 x 1.46 GHz, 1MB L2 cache, 7 W)
Intel® Atom™ E3845 (4 x 1.91 GHz, 2MB L2 cache, 10 W)


Industry 4.0 is ringing in new infrastructure requirements. What is needed are compact and reliable industrial computers, such as those based on the Pico-ITX form factor, that cannot only be trusted to perform tasks reliably, but that can also provide connectivity from use in the field up to the management level. The compact design with a footprint of 70x102mm makes the SBC highly versatile. Real-time capability and support for multiple operating systems allow use in demanding industrial applications such as mechanical engineering or automation and control systems. The Intel® Atom™ E3800 processors are also suitable for use in the extended industrial temperature range. Thanks to their low power consumption with just 5 to 10 Watt TDP, the single-chip Bay Trail solutions are ideal for passively cooled and enclosed systems that can be used in harsh environments. When high-performance graphics with extensive 3-D capabilities are not required, and when two independent displays with full HD resolution are sufficient, the Pico-ITX SBC from congatec proves to be reliable and cost effective. Typical applications include control of large machines with decentralized, distributed intelligence, robotics, all types of intelligent measurement and analysis devices, and high-performance IoT computers with low power consumption.

With the conga-PA3, congatec has released a powerful, low-power SBC with embedded qualities. The widespread and highly compact Pico-ITX form factor enables high volumes at low prices. Customers receive a robust SBC with a guaranteed availability of at least 7 years that is also suitable for 24/7 operation in harsh environments. Optional versions for the extended industrial temperature range of -40° to +85° C are also available.

Currently, there are two configurations: A dual-core Intel Atom E3826 and a quad-core Intel Atom E3845. Both processors are from Intel’s 64 bit Bay Trail family and are full System-on-Chips (SoCs) characterized by high efficiency and an excellent price/performance ratio. Additional CPUs can easily be implemented as tailored products when minimum production quantity levels are met.

The integrated Intel Gen7 HD graphics supports two independent displays in Full HD resolution (LVDS 2x24bit via an internal connector and DP++; and HDMI1.4 via a connector on the I/O panel). The hardware supports or directly accelerates DirectX 11.1, OpenGL 3.2 and OpenCL 1.2. The RAM memory is soldered to the board. Depending on the processor, a total of up to 4GB DDR3L-1666 are available. The I/O panel further provides two USB2.0 ports, an RJ-45 connector for 10/100/1000 GB Ethernet, plus a 12V DC power supply.

Also integrated are an additional USB 2.0 port, a USB 3.0 SuperSpeed port, a connector for backlight and LVDS, fan control, HDA audio, two serial ports (RS232, RS232/485/422), a SATA connection, a half-size slot for shared mSATA/miniPCIe, plus another half-size miniPCIe slot.

Various interfaces including ACPI 5.0, I2C bus and LPC bus allow easy integration of legacy I/O interfaces via the feature connector. Real-time clock (RTC) and Intel High Definition Audio complete the feature set.

Delivery of pre-assembled and pre-configured assemblies

On request, we can supply all of the assemblies we offer in series with cooling solutions, memory and I/O components and preconfigured BIOS default settings as per customer specifications. We will gladly assist you in creating the BIOS image with your bootlogo and the required default settings.

To match our CPU boards, we have a variety of system components, such as enclosures, cooling solutions, peripheral components, memory components and cable assemblies, with which we can offer short-term system configurations tailored to the requirements of the respective project. Many of these components can be delivered from stock in order to allow the rapid development of proof-of-concept prototypes.

Build-to-order service for customer-specific system configurations

Many of our customers would like to select the key components for their systems, but they see no added value in integrating the system components themselves and assembling the systems in production quantities.

Tailored solutions - even for smaller projects

With the right system concept, solutions that meet the requirements do not require high minimum order quantities. Bridging the gap to conventional information technology contributes to cost-optimized solutions in many of our projects.

Depending on the requirements of your project, we offer you a customized version of a standard product, a customer-specific solution based on modular function blocks or a completely customer-specific development.

On request we offer the following services:

- Design and implementation of project-specific system configurations according to requirements profile
- Configurable standard configurations based on pre-qualified components
- In-house development and SMD assembly of customer-specific assemblies and carrier boards
- 3D design of housing components, mechanical modifications and rebranding of standard systems
- Assembling customer-specific systems
- Configuration and installation of customer-specific BIOS and operating system / software images.
- Delivery of systems and preassembled material kits in customer-specific packaging including accessories such as documentation, power supply or cable sets.

Get in touch with us to discuss about your requirements. Together we work out a system concept tailored to your application.
