MNT Reform LS1028A Processor Module

Note: The 8 GB module version is discontinued in favor of streamlined production. If you bought the 8 GB module, you will be upgraded to the 16 GB module. The second batch is delayed due to chip shortages. We expect it to be ready in April/May 2024.

A Fully Open Hardware Processor Module.

The LS1028A is the open hardware system-on-module featuring the NXP Layerscape LS1028A processor with 16GB of DDR4 RAM. It can be used in the MNT Reform laptop or in any other custom device.


  • Fully open hardware design (Altium sources published, can be opened in KiCAD)
  • NXP LS1028A SoC is fully supported by mainline Linux
  • Ability to boot the system without any binary blobs (see next section for caveat)
  • 16GB DDR4 RAM
  • 2x Cortex-A72 cores at 1.5GHz
  • Big PCIe address space allows usage of some external AMD, NVidia GPUs (experimental)
  • Vivante GC7000UL GPU supported by open source Mesa graphics library


  • Roughly 30% higher power consumption than i.MX8MQ with 4GB RAM
  • 2 faster cores instead of 4 energy-efficient, but slower cores
  • No HDMI output. Secondary PCIe lane available on HDMI connector
  • eDP display requires a firmware blob. This can be worked around with a mPCIe/PCIe display adapter, but this takes up a PCIe slot
