## Description

LoRa-E5 is a low-cost, ultra-low power, extremely compact, and high-performance LoRaWAN Module designed by Seeed Technology Co., Ltd. It contains ST system-level package chip STM32WLE5JC, and STM32WLE5 is the first SoC integrated with the combo of LoRa RF and MCU chip. This module is also embedded with ARM Cortex M4 ultra-low-power MCU and LoRa SX126X and therefore supports (G)FSK mode and LoRa. The previous versions of the LoRaWAN module all require additional use of MCU (Microcontroller) to run the application code. Now, you can directly and immediately put the LoRa-E5 STM32WLE5JC Module into use to complete this process without the hustle of additional accessories. With the Stamp Hole form factor, LoRa-E5 enables you to integrate this module on your device’s mainboard conveniently. You don’t need to waste time and effort on designing your own device from scratch with the use of MCU and LoRa chip. Moreover, the module has already been certificated, so your completed device can be certified and approved by any agency cheaply and rapidly. Thanks to the innovative design, LoRa-E5 has a comparatively lower cost than other LoRaWAN modules. This will greatly save your budget in the whole process of product design. LoRa-E5 LoRaWAN® module is highly suitable for long-distance, ultra-low-power applications such as smart agriculture, smart city, wireless meter reading, sensor networks, wireless communication, and other low-power wide-area IoT scenarios. If you want a module to design your own LoRaWAN sensor, construct IoT nodes, or support any wireless communication applications, LoRa-E5 is the premium choice that provides you with an optimal user experience.**This LoRa E5 module is designed with industrial standards, hence it's highly suitable to be used in designing industrial IoT products, with a wide working temperature of -40°C ~ 85°C.**[](https://www.st.com/content/st_com/en/partner/partner-program/partnerpage/Seeed.html)Seeed is the official[ ST Authorized Partner](https://www.st.com/content/st_com/en/partner/partner-program/partnerpage/Seeed.html) to bring you STMicroelectronics solutions from Modules to Development Boards, one-stop prototyping services with Seeed Fusion, and integration customization.If you are not quite familiar with LoRa and would like to learn more about it including what is LoRa?

**Application Note**

**1. Factory AT Firmware**

LoRa-E5 series has a built-in AT command firmware, which supports LoRaWAN Class A/B/C protocol and a wide frequency plan: EU868/US915/AU915/AS923/KR920/IN865. With this AT command firmware, developers can easily and quickly build their prototype or application.

The AT command firmware contains a bootloader for DFU and the AT application. The "PB13/SPI\_SCK/BOOT" pin is used to control LoRa-E5 to stay in the bootloader or jump to the AT application. When PB13 is HIGH, the module will jump to AT application after reset, with a default baud rate of 9600. When PB13 is LOW (press the "Boot" button on LoRa-E5 Dev Board or LoRa-E5 mini), the module will stay in the bootloader, and keep transmitting "C" character every 1S at baud rate 115200.

**Attention**

1\. Factory AT Firmware is programmed with RDP (Read Protection) Level 1, developers need to remove RDP first with STM32Cube Programmer. Note that regression RDP to level 0 will cause a flash memory mass to erase and the Factory AT Firmware can't be restored again.

2\. The "PB13/SPI\_SCK/BOOT" pin on the LoRa-E5 module is just a normal GPIO, not the "BOOT0" pin of the MCU. This "PB13/SPI\_SCK/BOOT" pin is used in the bootloader of the Factory AT firmware, to decide to jump to APP or stay in bootloader(for DFU). The real "BOOT0" pin doesn't pinout to the module, so developers need to be careful when developing low-power applications.
