Description
Ebyte E32-433T30D-V8 SX1278 433MHz 1W LoRa UART Wireless Module
The Ebyte E32-433T30D-V8 LoRa Wireless Module is a long-range wireless serial communication module designed for IoT applications, industrial automation, remote monitoring, and wireless sensor networks. Powered by the Semtech SX1278 RF transceiver, it uses LoRa spread-spectrum technology to provide reliable data transmission with improved interference resistance.
Operating across the 410–441MHz frequency range, with a default frequency of 433MHz, the module delivers adjustable RF transmission power from 21dBm to 30dBm (up to 1W). Under manufacturer-specified open-area test conditions, it supports wireless communication distances of up to 8km with a suitable antenna.
Featuring a UART serial communication interface, the E32-433T30D-V8 enables convenient integration with Arduino, ESP32, STM32, and other compatible microcontrollers. Its configurable wireless settings, multiple operating modes, and built-in forward error correction (FEC) make it suitable for industrial telemetry and embedded wireless communication systems.
The module supports a 3.3V–5.2V DC power supply, industrial operating temperatures from -40°C to +85°C, and low-power sleep operation. Its DIP package and SMA antenna connector allow integration into custom PCBs and wireless electronic devices.

Compatibility Information
-
Compatible with microcontrollers supporting UART communication through suitable voltage-level interfaces.
-
Uses a 3.3V TTL communication interface; direct connection to 5V UART logic is not recommended.
-
Requires a suitable 433MHz antenna for RF operation.
-
Requires a power source capable of supplying the transmit current demanded at high RF output power.
-
Wireless range depends on antenna gain, installation height, terrain, obstacles, interference, and transmission settings.
-
This is a UART-based LoRa serial module, not a direct SPI breakout or a standalone LoRaWAN gateway.
Important: The 410–441MHz hardware frequency range and 1W maximum output are technical capabilities, not authorization to transmit at every frequency or power level. Users must comply with applicable Indian wireless regulations, licensing requirements, and permitted RF power limits.
