Wio-E5 Wireless Module (Bulk), for Long Range Application

Wio-E5 is a low-cost, ultra-low power, extremely compact, and high-performance Long Range Module designed by Seeed Technology Co., Ltd. It contains ST system-level package chip STM32WLE5JC, and this STM32WL module is the first SoC integrated with the combo of Long Range RF and MCU chip. This module is also embedded with ARM Cortex M4 ultra-low-power MCU and Long Range SX126X and therefore supports (G)FSK mode and Long Range .

The previous versions of the Long Range module all require additional use of MCU (Microcontroller) to run the application code. Now, you can directly and immediately put the Wio-E5 STM32WLE5JC Module into use to complete this process without the hustle of additional accessories. With the Stamp Hole form factor, Wio-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 Long Range 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, Wio-E5 has a comparatively lower cost than other Long Range modules. This will greatly save your budget in the whole process of product design.

Wio-E5 Long Range 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 Long Range sensor, to construct IoT nodes, or to support any wireless communication applications, Wio-E5 is the premium choice that provides you with an optimal user experience.

If you are not quite familiar with Long Range and would like to learn more about it including what is Long Range ? How does Long Range function? What are the pros and cons of Long Range ? Long Range network architecture, and applications of Long Range , etc., please check out this article LoRapedia, which introduces Long Range and Long Range in detail.

• Works for Long Range sensor nodes and any wireless communication application.
• Wireless Meter Reading, IoT Nodes,for Sensor Network, other low power wide area IoT scenarios

Since SenseCAP Long Range series products are targeting environmental-monitoring, especially in outdoor scenarios, such as smart agriculture, smart city, etc., the above use cases are mainly in these fields. There are many fields to explore scenarios such as smart metering for water, electricity, & gas; and smart homes, and other applications that need low-power, long-range remote monitoring. After designing your own Long Range devices with this Wio-E5 module, you can get your designs verified quickly with Seeed Fusion PCB and PCBA services, which can help turn your designs into prototypes in a few days. And when the design is verified, Seeed agile manufacturing services will help you scale up the prototypes into mass production, with services from Design for Manufacturing, procuring raw materials, to mass production and global shipment, and many services in between.

1. Factory AT Firmware

Wio-E5 series has a built-in AT command firmware, which supports Long Range 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 Wio-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 Wio-E5 Dev Board or Wio-E5 mini), the module will stay in the bootloader, and keep transmitting "C" character every 1S at baud rate 115200.
