Wireless Lora spreading module 433M RF E32-433T33D SX1278 RF chip wireless serial port module (UART) low power transmission

Product Descriptions

E32-433T33D is a wireless serial port module (UART) based on SEMTECH's SX1276 RF chip. It has transparent mode, working in the 410-441MHz (default 433MHz),LoRa spread spectrum technology.

SX1278 features LoRa spread spectrum, which will bring longer communication distance, and has the advantages of concentrated power density, meanwhile it has a very strong confidentiality.SX1278 is a milestone in the field of low-speed communication, and is favored by people in the industry. The default air rate is 2.4kbps, the transmit power is 33dBm, with PA power amplifier and LNA low-noise amplifier, so as to improve communication stability and extend communication distance. industrial-grade active temperature compensated crystal oscillator is used to ensure its stability and consistency.

Product Features

• Support advanced LoRa modulation method, with the advantage of long-distance anti-interference:

• Built-in PA+LNA, the communication distance can reach 16km under ideal conditions, and the transmission distance is better than traditional GFSK, etc.;

• Support fixed-point transmission, broadcast transmission, channel monitoring;

• Support air wake-up (ultra low power consumption), suitable for battery applications;

• Support FEC forward error correction to improve communication stability:

• Maximum transmit power 2W, multi-level software adjustable;

• Support global license-free ISM 433MHz frequency band;

• Support data transmission rate of 0.3k~19.2kbps:

• Support 3.3 ~ 5.2V power supply, more than 5V power supply can ensure the best performance:

• Adopt industrial-grade crystal oscillator, industrial-grade standard design, support long-term use at -40 ~ +85 °C.

• SMA-K interface for easy connection of coaxial cable or external antenna.
