## Blueprint

**Open firmware.** Firmware is GL.iNet's GPL OpenWrt fork (MT7621); the MM8108 HaLow radio has a public datasheet, but no router PCB schematics, Gerbers or BOM are published.

| Part | Role | Datasheet |
|---|---|---|
| MediaTek MT7621 | SoC (dual-core MIPS, 880 MHz) | https://www.mediatek.com/products/home-networking/mt7621 |

_Notes:_ GitHub code search across github.com/gl-inet for 'halow' returned zero results -- no device-specific hardware or firmware repo exists under that name; the shipped firmware is built from the shared gl-inet/openwrt + gl-feeds base (same repos GL.iNet uses across its router line). No schematics/Gerbers/BOM found anywhere. Chip identification (MediaTek MT7621 @880MHz, Morse Micro MM8108) confirmed by fetching gl-inet.com's own HaLowLink 2 product page directly.
