Variscite DART-6UL SoM, an Alternative to Intel Edison Module

Intel recently announced it will discontinue manufacturing and selling all SKUs of the Intel® Edison compute modules and developer kits.

The initial version of Edison was released in the beginning of 2014, with a second version being released by the end of 2014. It was intended for the IoT market, with dimensions of 35.5x25x3.9mm. The Edison features an Intel Atom processor, consisting of two Atom Silvermont cores running at 500MHz. It includes a fixed configuration of 1GB integrated RAM, and 4GB eMMC flash on-board. Dual-band (2.4GHz and 5GHz) Wi-Fi, Bluetooth 4.0 and USB controllers complete the package.

According to Intel’s announcement, the last shipment of Edison family boards is planned for December 2017. This announcement will have a critical impact on companies that already integrated the Edison board in their products, as well as the many companies that engaged in the development process of integrating the Edison board into their products.

While some of these companies are rushing to place their orders by the end of the year, other companies are already looking for an alternative candidate to replace the Edison module. Naturally, the Edison alternative should be somewhat similar to the original selection, at least in terms of interfaces and connectivity. But if you are looking for an alternative solution, you should take into account that this is a rapidly evolving market, so the alternatives offered today can deliver higher performance solutions than those delivered in 2014, when Intel launched Edison.

One suitable alternative for the IoT segment is the DART-6UL System on Module platform, developed by Variscite. The DART-6UL, measuring only 25x50mm, is a highly flexible SoM based on NXP i.MX 6UltraLite / i.MX 6ULL ARM Cortex™-A7 processor, with frequencies up to 900MHz.

The following comparison table will help you see the similarities and the upgraded features:

And the all-important missing bit:- “Starting from $24”

Even though the article fails to credit the original author and appears to be attributed to CNXsoft, the style of the language makes it obvious that CNXsoft did not write the article and it is a cut’n’paste job.

I’ve tried to use this board and can say that it has nearly no support especially in security area. Seems like this is usual tendency for the NXP company and partly for Variscite. All you would get – are the muddy responses at the NXP forums and silence from Variscite. It is pity that such good Freescale CPU became unusable because of this. If you are brave enough – there are exists much more suitable choices like Phytec.

It’s incorrect to compare 64-bit SoC vs. 32-bit one. BT is BLE as well there.

Moreover, Edison runs vanilla kernel, so, any distro can be set up there.
