From the project
MM8108-based adapters in different form factors for EU availability of sub-GHz halow 802.11ah hardware - mainly for decentralised networking (Reticulum mesh) and distributed IoT experimentation purposes.
Low-cost experimental hardware platform for Morse Micro MM8108 Wi-Fi HaLow (802.11ah) modules. USB-A carrier board is the current reference design, with additional form factors planned (M.2, USB-C/PCIe, HAT-style).
Focus: cost reduction vs official evaluation hardware, wireless networking experimentation, Reticulum mesh comms, IoT/embedded.
- Reduce cost vs official MM8108 dev kits / dongles - Optimize for low-cost PCB fabrication (JLCPCB / PCBWay class vendors) - 2-layer 1.6mm FR4 standard stackup - Relaxed DFM (large vias, conservative routing constraints) - Use widely available low-cost…
