Introduction

The E32-433T37S is a wireless serial module (UART) based on a SEMTECH high-performance RF chip, featuring multiple transmission modes. It operates in the 410~441MHz frequency band (default 433MHz), employs LoRa spread spectrum technology, outputs TTL levels, and supports a supply voltage of 4.5V~15V. The module adopts the latest-generation LoRa spread spectrum technology, offering faster speeds, lower power consumption, and a smaller form factor compared to conventional solutions. It supports features such as over-the-air wake-up and wireless configuration, with custom development services also available.

Features

• Developed with SEMTECH high-performance RF chip using new LoRa spread-spectrum modulation technology for extended communication range and enhanced anti-interference capability.
• Supports FEC forward error correction for improved communication stability.
• Supports air wake-up (ultra-low power consumption mode) for battery-powered applications.
• Supports point-to-point transmission, broadcast transmission, and other transfer modes.
• Supports deep sleep across full supply voltage range; total current consumption less than 10μA in this mode.
• Supports license-free global ISM 433MHz band.
• Integrated PA + LNA; communication range up to 25km under ideal conditions.
• Parameter retention after power-off; module resumes operation with configured parameters upon power-on.
• Efficient watchdog design; module automatically restarts and resumes operation with previous parameter settings upon any abnormality.
• Data transfer rate: 0.3K ~ 19.2kbps.
• Wide supply voltage: 4.5~15V; guaranteed 37dBm power output across full supply voltage range.
• Industrial-grade design; supports long-term operation at -40 ~ +85°C.
• Maximum output power up to 5W (37dBm) for longer range and more reliable transmission.
• Built-in under-voltage and over-voltage warning with indicator LED.
• Built-in over-temperature protection; transmission automatically halted when module temperature exceeds maximum rating.
• Matrix pads reserved on the bottom of the module for secondary development heat dissipation.
