Raw Blame History

This mini carrier board was developed alongside the LattePanda Mu Ultra compute module (based on the Intel Lunar Lake processor). The carrier board is code-named Lunar Lake IO Board, or LIO for short, which is the origin of the "LIO" suffix in the BIOS name.

These BIOS firmwares enable the LattePanda Mu N100 / N305 compute module to be compatible with the DFR1293 Mini Carrier Board.

💡Note: The LattePanda Mu compute module is available in 8GB and 16GB memory versions. It is essential to select the correct BIOS firmware as described below.

  • For LattePanda Mu N100 8GB RAM Model:

    • S70NC1R200-8G-B-LIO-001

  • For LattePanda Mu N100 / N305 16GB RAM Model:

    • S70NC1R200-16G-B-LIO-001
