Cellular module specialist Sierra Wireless has unveiled its latest attempt at promoting IoT hardware interoperability, with support from Freescale, Texas Instruments and Linear Technologies. The open hardware reference design is supported by another open interface standard developed by Sierra, and the support of three prominent chip makers bodes well for adoption. The target is to develop an IoT equivalent of the Mini PCIe connector, which allows components from multiple vendors found in laptops and desktops to be swapped by developers and customers alike. With the new hardware interface, different IoT modules can be combined to create new designs and implementations. The first mangOH (Open Hardware, presumably) connector will be found in the open hardware reference design that has already been…
