CDSENet E32-433T20DT LoRa SX1278 RF Module 433MHz

Description

The CDSENet E32-433T20DT is a professional-grade LoRa RF module built around the industry-standard SEMTECH SX1278 spread-spectrum transceiver. It delivers up to 1W (30dBm) of configurable RF output power, paired with a high-sensitivity receiver capable of decoding signals as low as -146dBm. This combination enables reliable communication over distances exceeding 3 kilometers in open terrain, making it ideal for remote telemetry and sensor networks.

The module operates on the global 433MHz ISM frequency band, with software-configurable channels spanning from 410MHz to 441MHz. It communicates via a simple UART TTL serial interface, functioning as a wireless serial port replacement that handles all LoRa packetization and modulation internally. The integrated 512-byte data buffer manages flow control, while the wide 2.3V to 5.5V operating voltage allows direct connection to 3.3V or 5V microcontroller systems without level shifting.
