Open-spec i.MX8M Mini SBC sells for $99

Apr 23, 2021 — by Eric Brown — 4417 views

MYIR’s $99 “MYS-8MMX” SBC runs Linux on an i.MX8M Mini with 2-4GB DDR4, 8-128GB eMMC, NVMe-ready M.2, GbE, WiFi/BT, HDMI, CSI, 3x USB ports, and options including -40 to 85°C support and an enclosure.

In 2019, MYIR introduced a MYC-C8MMX module and MYD-JX8MX dev kit based on NXP’s i.MX8M Mini. The company has now followed up with an open-spec MYS-8MMX SBC based on the Mini. The MYS-8MMX is also available in a MYS-8MMX Box system. Applications include consumer electronics, industrial automation, smart healthcare, security monitoring, and more.

The 95 by 69mm MYS-8MMX joins other SBCs based on the i.MX8M Mini including SolidRun’s HummingBoard Ripple, Gateworks’ Venice, and others. Unlike the i.MX8 and i.MX8M, the i.MX8M Mini lacks 4K video, but it’s faster and more power efficient than the i.MX8M. In addition to the 4x -A53 cores, there are GCNanoUltra (3D) and GC320 (2D) graphics cores and a 400MHz Cortex-M4 MCU.

The MYS-8MMX runs Yocto 3.0 or Ubuntu 18.04 on the quad-core Mini, which is clocked to 1.8GHz for the 0 to 70°C model and 1.6GHz for the -40 to 85°C SKU. MYIR is supplying kernel and driver source code, a detailed user manual, and schematics. There is no forum, but MYIR offers a FAQ and online tech support.

Media features include an HDMI port, LVDS with touchscreen support, and MIPI-CSI. Dual 25-pin expansion connectors support I/Os ranging from digital audio to I2C.

    The term “open-spec” can involve several factors. For our purposes, we call a board “open-spec” if it fulfills most of the open source criteria. This ranges from community resources to strong open source software support to open schematics and open licensing.
