i.MX8M Mini SBC aims for industrial HMI

Mar 23, 2020 — by Eric Brown 2,754 views

Garz & Fricke’s “Tanaro” SBC runs Linux or Android on an i.MX8M Mini with 2x Ethernet, mini-PCIe, LVDS with optional touchscreens, and isolated CAN and serial ports.

Garz & Fricke announced a “coming up” Tanaro (or Tanaro Core) SBC that features NXP’s quad -A53, 1.8GHz i.MX8M Mini Quad, the faster, but HD-only cousin to the i.MX8M. It follows other Garz & Fricke SBCs including its smaller, i.MX6 ULL based Nallino Core, as well as other Mini-based SBCs including Seco’s SBC-C61 and Boundary Devices’ Nitrogen8M_Mini.

Manufactured in Hamburg, Germany, the 159 x 80 x 18mm Tanaro has a 0 to 60°C range and wide-range 9-32V power. The SBC is designed for Human Machine Interface (HMI) panel-PC applications and is available with flush, rear, and panel mounts, with optional touchscreens from 7 to 32 inches.

The Tanaro runs Yocto based Linux or Android on the quad-core version of the Cortex-M4 equipped Mini. RAM tops out at 1GB LPDDR4 instead of 2GB or 4GB for the SBCs listed above. There’s also 4GB MLC eMMC and a microSD slot.
