Description

A professional 433MHz two-way wireless communication module with a range of up to 1200 meters via a serial UART interface.

The long-range wireless communication module (GT-38 RF Wireless Serial Module) is the professional and most stable engineering solution for wireless data transmission over vast distances, designed to connect microcontrollers such as Arduino and others for exchanging text and digital data as a direct and independent wireless alternative to traditional serial cables.

This module is considered the Benchmark standard in (UART RF) wireless communication technology; it relies on advanced industrial chips Silicon Labs SI4438/SI4463 integrated with a flexible antenna (Spring Antenna). The module allows two-way data transmission (Half-Duplex) with a huge coverage range of up to 1200 meters in open space, and at a frequency of 433MHz which is characterized by a high penetration capability for walls and obstacles compared to Wi-Fi and Bluetooth frequencies. The board features an integrated microprocessor that automatically manages the communication protocol (fully transparent - Transparent Transmission); this means that any data sent to the TX port at the first end will immediately exit from the RX port at the second end without the need to write complex programming codes or manage wireless communication libraries. It is the professional and sole choice for building remote control systems for drones and smart cars (RC), reading farm and weather sensors remotely, controlling industrial devices, advanced STEM projects, and the Internet of Things (IoT).

A premium, industrial-to-hobby grade GT-38 433MHz RF wireless serial port transceiver module precision-engineered for rock-solid, ultra-long-range data telemetry up to 1200 meters. Standing as the definitive hardware benchmark for transparent wireless UART communication, this high-performance assembly is driven by the advanced Silicon Labs SI4438/SI4463 RF core embedded with an automated microcontroller subsystem. Operating on the sub-GHz 433MHz band, it offers superior structural penetration and environmental noise immunity compared to standard 2.4GHz links. Designed for true plug-and-play transparency, any data written to the local TX pin instantly populates on the remote RX node, mimicking a physical wire over immense distances. Complete with a high-gain spring antenna and multiple operating modes (including ultra-low power sleep states), it serves as an indispensable hardware asset for long-range drone telemetry, outdoor agricultural sensor meshes, remote industrial automation, and advanced academic STEM robotics.
