Collection of small hardware projects and KiCad designs developed as experimental ones

Projects

• mllse-m2-air-breakout-board

  • Breakout board and modification guide for the MLLSE M2 Air mini PC. Provides two full-size M.2 Key-B SATA slots and one M.2 Key-M PCIe x1 slot, includes KiCad project, BOM, gerbers, and step-by-step modification instructions.

• radxa_a5e_m2_to_rasp_pcie

  • M.2 Key-M to Raspberry Pi PCIe adapter for the Radxa A5E SBC. Allows using Raspberry Pi PCIe HATs via a Raspberry Pi PCIe FPC cable.

• gl_inet_gl_mt300n_v2_flash_expansion

  • Guide and patch for upgrading the SPI NOR flash in the GL.iNet GL-MT300N-V2 from 16 MB to 32 MB or 64 MB. Covers full flash backup, OpenWrt custom image compilation with a DTS/Makefile patch, flash image assembly, programming with a CH341A programmer via flashrom, and physical IC replacement.

• radxa_3a_m2_to_mpcie_router

  • M.2 Key-M to Mini PCIe breakout board for the Radxa Rock 3A SBC, designed to enable use of AP-grade Mini PCIe Wi-Fi cards. Includes KiCad project, OpenSCAD enclosure files, and a full OpenWRT flashing and setup guide.

• rpi_cm_cluster

  • Unfinished 4-node Raspberry Pi Compute Module cluster (1 control + 3 compute nodes) across two linked PCBs, with capacitive-coupled Gb Ethernet switching. Abandoned due to CM pricing; kept as a reference base for other projects.
