Debix Model A packs i.MX 8M Plus and mirrors RPI form factor

Jul 16, 2022 — by Giorgio Mendoza 2,389 views

The Debix Model A from Polyhex is a Single Board Computer (SBC) built around the i.MX 8M Plus Quad-core ARM Cortex-A53 CPU industrial-grade processor. This SBC integrates a 2.3 TOPS Neural Processing Unit and expandable storage to target industrial automation, multimedia, and other IoT applications.

The Debix Model A was designed by Polyhex Technology and it’s based on the NXP NPU i.MX 8M Plus industrial processor with maximum frequency of 1.6GHz. By default, this device comes with 2GB of LPDDR4 but can be upgraded to 4GB or 6GB. The default storage interface provides support for an SD Card but can also be customized to provide eMMC support from 8GB up to 128GB.

Connectivity is enabled via Wi-Fi with dual frequency support (2.4GHz & 5GHz) and Bluetooth 5.0. There is also a GbE RJ45 with Power over Ethernet support, however it needs a POE power supply module. The board also offers 12 pins for an additional LAN connection. 

For display support, there is one HDMI, one DSI output, and LVDS supports via pin headers next to the LAN pins. See below for details.

    Waste of money
    Raspberry pi 3 have better cpu and cost half

  2. RP is good for educational market not for Industrial market.
