MNT Reform LS1028A Module (Preorder)
This is the open hardware system-on-module featuring the NXP Layerscape LS1028A processor and 16GB of DDR4 RAM. It can be used in the MNT Reform open hardware laptop or in any other custom device.
Important note on Preorder Process
Update 2023-05-17: Our trial run was successful, and we are preparing a production run of 16GB modules. The 8GB module version is discontinued in favor of streamlined production. If you bought the 8GB module, you will be upgraded to the 16GB module.
Benefits
- 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. These have roughly double the single-core performance of the Cortex-A53 in i.MX8MQ.
- Big PCIe address space allows usage of some external AMD, NVidia GPUs (experimental).
- Vivante GC7000UL GPU supported by open source Mesa graphics library.
Drawbacks
- 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.
