Improved 4.2 Bluetooth and New SoM Configuration with 800MHz and 900 MHz Processors

Variscite is excited to announce yet further innovation with our latest new release. Continuing to optimize our SoM portfolio, we’re adapting products to the dynamic and fast-growing embedded markets in which our customers operate.

After recently announcing the expansion of the DART-6UL module configuration options, we’re offering a new SoM configuration with enhanced CPU clock speed, applicable to commercial and industrial applications:

  • 900 MHz for commercial temperatures (0 to 70 °C)
  • 800 MHz for industrial temperatures (-40 to 85 °C)

The new configuration will be available alongside the existing, popular clock speed configurations – 528 MHz and 696 MHz – with a longevity commitment until 2030.

The enhanced 800/900 MHz i.MX 6ULL, Cortex-A7 speed grades are pin-to-pin compatible with existing DART-6UL configurations. As such, this enables Variscite’s present customers to upgrade their DART-6UL based devices with higher performance. It also accommodates new customers looking to develop on a platform with enhanced functionality, at a very competitive system cost.

The upgrade of the BT/BLE 4.2 module will be available for the entire DART-6UL product-line, bringing significant improvements in speed and security features. This new technology has a direct and considerable impact on IoT devices, particularly those with critical privacy requirements.

The DART-6UL new configurations will support a wide range of interfaces such as fully certified Wi-Fi/BT, Ethernet PHY, 2D Pixel acceleration engine and Audio Codec. Significantly optimized, the product still retains a compact size (measuring only 25 mm x 50 mm), high power capability and attractive price-point – starting from only 24 USD.


Variscite delivers an all-inclusive solution by providing production-ready software suits for the DART-6UL SoM, covering Linux Yocto, Linux Debian, Linux Boot2QT and Android. These solutions significantly ease development efforts and dramatically shorten time-to-market.


Ofer Austerlitz, Variscite VP of Business Development and Sales explained the push to constantly extend the company’s portfolio.
“Our industry is ever-evolving with process enhancements, as well as more advanced tools and features being absorbed into the embedded market. As such, Variscite understands the importance of remaining a cutting-edge SOM vendor while developing products that anticipate and fully accommodate our customers’ needs, both from a commercial and technical aspect.”
