Newark Element14 launched the RIoTboard, a $74 open source SBC for IoT applications that runs Android 4.3 or Linux 3.0 on a 1GHz Freescale i.MX6Solo SoC.
The “Revolutionizing the Internet of Things” (RIoT) single board computer is designed for a variety of Internet of Things (IoT) and other low-power embedded applications, says Newark Element14, a Chicago based distributor owned by Premier Farnell. Premier Farnell recently launched an ARM9-based EDM6070AR-01 SBC and HMI system. Both the RIoTboard and the EDM6070AR-01 are backed up by the company’s Element14 developer community, and supported with open source code and full schematics.

The RIoTboard runs on the single-core Solo version of Freescale’s Cortex-A9-based i.MX6 system-on-chip, running at up to 1GHz. For years, the Solo, which offers a 3G accelerator, but not an HD video accelerator, has been overshadowed by the dual- and quad-core i.MX6 models. However, with the recent interest in IoT applications, the low-power SoC seems to be gaining more traction. Last month, for example, Freescale announced a tiny i.MX6Solo-based SBC aimed at the wearables market called the Warpboard.
The RIoTboard is equipped with 1GB of DDR3 RAM, twice that of the Wandboard Solo. It also offers 4GB eMMC, a microSD slot, and an undercarriage SD slot. By comparison, the Wandboard Solo has dual microSD slots, but no pre-installed flash.

As with the WandBoard Solo, there’s no built-in WiFi or Bluetooth. Both boards get by with gigabit Ethernet ports, as well as whatever wireless dongles one adds to the USB ports. Once again, the RIoTboard has the upper hand here, providing four USB 2.0 host ports, as well as a mini-USB OTG port. The Wandboard Solo has one each.
Like the WandBoard, the RIoTboard features a coastline HDMI port. Somewhat unusually, it also offers a coastline LVDS port, which Newark says supports an LVDS8000-97C adapter board from Embest. Audio ports round out the coastline connections.
Other RIoTboard onboard interfaces are more similar, including camera and serial interfaces. The RIoTboard features a variety of expansion interfaces including GPIO, I2C, SPI, and PWM. Unlike the Wandboard, the RIoTboard adds JTAG and parallel RGB interfaces. The one major I/O advantage provided by the Wandboard is its S/PDIF connection.

The 120 x 75mm RIoTboard runs on a 5V power supply and supports a commercial 0 to 50°C temperature range. Android 4.3, Linux 3.0, and Ubuntu Linux stacks are available for download at the Element14 community, which also offers manuals, schematics, and Freescale CodeWarrior and ARM DS-5 development tools. A variety of debuggers, emulators, and other development tools are also available.
In contrast to the WandBoard, the RIoTboard is truly a single-board design — a distinction that could be cast as either an advantage or a disadvantage, depending on your perspective. The 95 x 95mm WandBoard uses a COM-plus-baseboard “sandwich” design, which makes it more complex but eases the task of customizing the aggregate assembly.
