SBC-U5A & SBC-U5C – Credit Card sized SBC (i.MX6 ULL)

Novasom Industries’ U5 is a small board, approximately credit card size, that consumes little power, but that can do much more than what you think thanks to the ARM core A7 and the optimization of our SW systems. Arrives with all necessary to guarantee an immediate bootstrap, driving an RGB display with its backlight and touchscreen, connecting via Ethernet and USB plus one strip for GPIO expansion.

The SBC-U5A and SBC-U5C are both RASPMOOD models with RPi footprints and 40-pin GPIO (25 usable). They run the usual Yocto Project Linux stack (Linux 4.1.15) on the power-sipping, 900MHz i.MX6 ULL.

The SBC-U5C stands out with its certified WiFi radio with external antenna, wide-range 6.5-18V input (vs. 5V), and battery charger. Otherwise, the boards seem to be the same, providing 512MB RAM, a 3.5mm audio jack, a USB 2.0 host port, and a 10/100 Ethernet port.


  • RASPMOOD design
  • several interface
  • two different Wi-Fi/BT modules availablePIO
  • Linux OS
  • Power supply 5V, optional 6.5 to 18V
  • RGB FPC display port with power supply for the backlight too
  • RTC with extarnal battery connector and on board resistive touch controller
  • Various GPIO, A/D I2C, SPI, UART 2xRS232 (1 for Console) + 1xCAN
  • UPS manager with external battery

SBC-U1 – Stamp Sized SBC (ESP32)

Novasom Industries’ U1 is little like a postal stamp, includes a Wi-Fi/BT module, a dual core CPU with a RT O.S, some, ready to use in the field, GPIO and some analog input. Probably is the smallest SBC available on the market.

The 5V SBC-U1A ships with 384KB DDR3 and 4MB flash and supports -40 to 85⁰C temperatures. I/O includes SPI, I2C, A/D, D/A, and up to 15x GPIO. An RTC is onboard. Other details for all three U-line boards may be found in the chart farther above.

An instrument through a graphical interface, allows you to configure the linux kernel in a simple and intuitive thus optimizing the performance of the card. The SDK, is a complex set of SW
which allows you to program a user code, configure the operating system “kernel” with appropriate video, set boot parameters, select specific peripheral drivers and their configuration etc.

Many use Yocto (also supported by Novasom) as SDK which, apart from being very heavy and variable over time (it is an example of the instability of Linux distribution because it is in continual evolution), is programmed in lines of code. In this case an operation as simple as a monitor substitution can become very complex.
Our tested and 100% guaranteed SDK isn’t a distribution like Yocto, even though the latter can be installed on the Novasom board, but is our SW toolsuite named NovaEmbed™ which allows the programming of the Novasom embedded system at a kernel-BSP and Boot level in a visual and preset way this reduces “time to market” in the development of embedded Linux application (which normally require highly specialized personnel and more time) and guarantees no errors resulting from the command line programming of the traditional SDK.
