Rakwireless RAK633: OpenWrt Compatibility Report
The Rakwireless RAK633 runs OpenWrt 25.12.2 on the ramips/mt76x8 target, and has been supported since 19.07.0. Its WiFi 4 (N) wireless on the mt76 driver rates fair for open-source driver support (0.65/1.0), installation is rated moderate, and we have no current US retail listing for it. Its wireless does not work correctly under OpenWrt, so it is listed here for reference rather than as a recommendation.

Installing OpenWrt on the RAK633
Installation on this device is rated moderate. Expect to use a recovery mode, TFTP or a vendor tool rather than a plain web upload. Documented methods: U-Boot TFTP + serial recovery, see git-commit.
Flashing third-party firmware can brick a router and usually voids the warranty. Always check that the firmware image matches your exact hardware version.
