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.
