WS-431E Industrial 4G router

Waveshare says the router supports DIN rail mounting, wall mounting, and tabletop installations. There’s no information about memory, storage, and even the operating system used. But the PDF user manual in the wiki has some screenshots that look like a customized LuCi interface from OpenWrt. VPN support includes OpenVPN, but not the more performant WireGuard implementation.

The WS-431E 4G industrial 4G router can be purchased on Aliexpress for $119.59 including shipping or on Waveshare store for $99.99 plus shipping.
