Data Sheet

1 Introduction

LoRa-E5 is a low-cost, ultra-low power, ultra-small size LoRaWAN

module designed by Seeed Technology Co.,

Ltd. The module uses ST system-level package chip STM32WLE5JC, embedded high-performance LoRa

chip

SX126X and ultra-low power Consumption of MCU. The target application of this module is wireless sensor

networks and other Internet of Things devices, especially battery-powered low power consumption and long-

distance occasions.

This specification mainly describes the hardware information, hardware performance and application

information of the module.

LoRa-E5 LoRaWAN

module is mainly suitable for long-distance, ultra-low-power applications such as wireless

meter reading, sensor networks, and other low-power wide-area IoT scenarios.
