Tiny i.MX8M Module Focuses on Streaming Media

By Eric Brown

Innocomm announced a 50 mm x 50 mm “WB10” module with an NXP i.MX8M Quad SoC, 8 GB eMMC, Wi-Fi-ac, BT 4.2, GbE, HDMI 2.0 with 4K HDR and audio I/O including SAI, SPDIF and DSD512.Among the many embedded products announced in recent weeks that run NXP’s 1.5 GHz, Cortex-A53-based i.MX8M SoC, Innocomm’s 50 mm x 500 mm WB10 is one of the smallest. The top prize goes to Variscite’s SODIMM-style, 55 mm x 30 mm DART-MX8M. Like Emcraft’s 80 mm x 60mm i.MX 8M SOM, the home entertainment focused WB10 supports only the quad-core i.MX8M instead of the dual-core model. Other i.MX8M modules include Compulab’s 68 mm x 42mm CL-SOM-iMX8.

The i.MX8M SoC incorporates a Vivante GC7000Lite GPU and VPU, enabling 4K HEVC/H265, H264, and VP9 video decoding with HDR. It also provides a 266MHz Cortex-M4 core for real-time tasks, as well as a security subsystem.

The WB10 module offers only 2 GB LPDDR4 instead of 4 GB for the other i.MX8M modules, and is also limited to 8GB eMMC. You do, however, get a GbE controller and onboard 802.11 a/b/g/n/ac with MIMO 2×2 and Bluetooth 4.2.

The WB10 is designed for Internet audio, home entertainment, and smart speaker applications, and offers more than the usual audio interfaces. Media I/O expressed via its three 80-pin connectors include HDMI 2.0a with 4K and HDR support, as well as MIPI-DSI, 2x MIPI-CSI, SPDIF Rx/Tx, 4x SAI and the high-end DSD512 audio interface.

You also get USB 3.0 host, USB 2.0 device, 2x I²C, 3x UART and single GPIO, PWM, SPI, and PCIe interfaces. No power or temperature range details were provided. The WB10 is also available with an optional, unnamed carrier board that is only slightly larger than the module itself. No more details were available. Further information

No pricing or availability information was provided for the WB10. More information may be found on Innocomm’s WB10 product page.
