8km UART Through Hole RF Transceiver Modules and Modems RoHS,3.3V~5.2V,-40 ~ 80C
The E32-433T30D is based on the Semtech SX1278 LoRa chipset and uses LoRa spread-spectrum modulation to achieve long-distance, highly reliable wireless communication even in noisy environments. It communicates with a microcontroller via UART (serial interface), making it easy to integrate with Arduino, ESP32, STM32, and similar systems.
It is commonly used for IoT telemetry, remote control systems, sensor networks, and industrial monitoring, especially where GSM/Wi-Fi is unavailable or impractical.
Key Features
Frequency range: 410–441 MHz (433 MHz default)
RF output power: 21–30 dBm (up to 1 W high-power version)
LoRa modulation: High sensitivity and strong anti-interference
Communication distance: up to ~8 km (open area, ideal conditions)
Interface: UART TTL serial (3.3 V logic level)
Sensitivity: around -147 dBm for long-range reception
Low data rate support: ~0.3 kbps to 19.2 kbps
Half-duplex communication (TX/RX not simultaneous)
Configurable modes: normal / wake-up / power-saving / sleep via M0 & M1 pins
Compact module size with SMA antenna connector
Wide operating temperature: -40 °C to +85 °C
Important Notes
Requires external microcontroller (MCU) for operation (not standalone).
Must not leave M0 and M1 pins floating (must be defined HIGH/LOW or GND).
Works best with proper 433 MHz antenna (2–5 dBi recommended).
Power supply must be stable (typically 5V with sufficient current capability).
For maximum range, line-of-sight + correct antenna height matters more than raw power.
Applications
Smart agriculture monitoring
Remote sensor networks
Utility meter reading (water/gas)
Industrial telemetry systems
Drone/robot communication links
Remote control & automation systems
