3.5-inch i.MX8M SBC focuses on A/V

Mar 18, 2019 — by Eric Brown 591 views

Seco’s 3.5-inch “SBC-C20” runs Linux on a dual- or quad-core -A53 i.MX8M SoC with up to 2GB RAM and 16GB eMMC plus 4K-ready eDP or HDMI 2.0, M.2 expansion, and optional -40 to 85°C.

The SBC-C20 is the third and final SBC announced by Seco at Embedded World. It’s not as fast as the i.MX8 QuadMax based SBC-C43 and not quite as customizable as the i.MX8M Mini powered SBC-C61, but considering the widespread availability of the well-traveled i.MX8M, it’s likely to ship sooner than its siblings. The media-rich, 3.5-inch SBC targets “cost-effective solutions in the multimedia field as well as for IIoT applications.”

Other i.MX8M based SBCs include Boundary Devices’ Nitrogen8M, Arrow’s 96Boards CE Extended Thor96, SolidRun’s HummingBoard Pulse, and the armStone MX8M from F&S. There are also sandwich-style carrier boards sold as SBCs such as CompuLab’s SBC-iMX8 Evaluation Kit and Variscite’s VAR-DT8MCustomBoard SBC.

The SBC-C20 runs Yocto Linux, Wind River Linux, and Android on Dual, QuadLite (no VPU), and Quad i.MX8M models of NXP’s up to 1.5GHz Cortex-A53 SoC. The SoC integrates a Cortex-M4F real-time core and a 4K-ready Vivante GC7000Lite/GC7000VLX GPU.

Up to 2GB of soldered DDR3L is available along with an option for up to 16GB eMMC. Options include an LVDS interface and the ability to swap the standard eDP connector for a similarly 4K ready HDMI 2.0a port. Other options include WiFi with Bluetooth LE 4.2, a 10W amp, a USB 2.0 touch controller, and -40 to 85°C support.
