3.5-inch i.MX6 SBC wants to power your vending machine

Mar 5, 2020 — by Eric Brown 4,318 views

Nexcom’s Embux subsidiary has launched a 3.5-inch “EBC3A1-1G Y0” SBC that runs Linux on an i.MX6 and offers wide-range power, -20 to 65°C support, dual CAN, and dual mini-PCIe slots.

The growing adoption of NXP’s i.MX8 SoCs has finally slowed the spread of its mighty i.MX6, which dominated mid-range, Arm-based embedded Linux devices for much of the last decade. But if your main goals are low cost, low power consumption, and gobs of interfaces, there’s still a lot to like about the venerable i.MX6. Nexcom’s Taiwan-based Embux subsidiary has launched an i.MX6-based 3.5-inch board, which is called the EBC3A1-1G Y0 on the Nexcom website and EBC 3A1-1G on the Embux site.

Nexcom is aiming the EBC3A1-1G Y0 at automated vending machines, parking kiosks, charging stations, and ATMs. Industrial automation and in-vehicle applications are also mentioned. The 146 X 102mm SBC loads up the 1GHz i.MX6 DualLite and ships as a default with a Linux stack based on Yocto Daisy 1.5.2, with Windows Embedded Compact 7 available as a “customization.”


The 146 X 102mm EBC3A1-1G Y0 is a larger, but similarly featured, version of the Embux-built, 146 x 72mm ICM-3011, which is resold by OnLogic (formerly Logic Supply). OnLogic also offers an i.MX6-based Embux board called the ICM-2010 that uses the smaller Pico-ITX form factor and is available in an ICS-2010 mini-PC version.


The EBC3A1-1G Y0 ships with 1GB RAM and 4GB eMMC and offers coastline ports, including 2x USB 2.0, micro-USB OTG, GbE, and HDMI. There’s an LVDS interface, and multiple serial, USB, CAN, and GPIO headers.

Two mini-PCIe slots are accompanied by a SIM slot. The SBC has a -20 to 65°C operating range and a 10.8-26.4V DC input.
