The AG-702 is said to run OpenWrt 23.05 with the Atreyo Environment V1.01b and Linux kernel 5.15.71. The default firmware supports various features such as VPN (OpenVPN, WireGuard, etc..), ModBus (TCP slave, TCP master, RTU master, RTU gateway),  and remote management through a Web UI, SSH, SNMP, MQTT(s), and so on. Atreyo also provides an SDK allowing users to develop their own application(s) for the gateway. Additional information about the hardware and software can be found on the documentation website.

Atreyo told CNX Software the AG-702 industrial OpenWrt gateway is available now with pricing starting at $125 without cellular and GNSS connectivity. I can also see they have offices in India and Poland, so European companies should also be able to easily source the gateway. More details may be found on the product page.
