Adeunis ARF44 UART TTL Module User Guide
This guide describes the ARF44 radio transceiver, which converts serial data to a half‑duplex radio frame in the 863‑870 MHz band. It details the module’s interface, mechanical dimensions, signal pins, and the AT command set used to configure operating parameters such as channel selection and power modes.
The document also covers antenna requirements, noting that the module has no printed antenna and must be fitted with an external 4‑wave (8.6 cm) antenna or a 50 Ω coaxial connection. Technical specifications such as output power, sensitivity, operating voltage, current consumption, temperature range, and dimensions are listed, along with firmware version history.
