    Everyone is talking about LoRa nowadays which is become a great initiative for WiFi in the IoT ecosystem to build communication in a wide range and use low power. We bring to you new LoRa family members, Grove LoRa-E5 embedded with LoRa-E5 STM32WLE5JC Module which is a high-performance and easy-to-use wireless radio LoRa module supporting LoRaWAN protocol.

    LoRa-E5 LoRaWAN STM32WLE5JC module is the major functional part integrated into Grove - LoRa-E5. It is a LoRaWAN module that embedded with ARM Cortex M4 ultra-low-power MCU core and LoRa SX126x, as the world-first combo of LoRa RF and MCU chip into one single tiny module, it supports (G)FSK, BPSK, (G)MSK, and LoRa modulations, and is FCC, CE certified. Grove - LoRa-E5 features extremely compacted size, ultra-low power consumption, low cost, and amazing performance.

    Note: Please check out this article LoRapedia, which introduces LoRa and LoRaWAN to learn about LoRaWAN and LoRa technology in detail.

    By connecting Grove - LoRa-E5 to your development boards, your devices are able to communicate with and control LoRa-E5 conveniently by AT command through a UART connection. Grove LoRa-E5 will be a superior choice for IoT device development, testing, and long-distance, ultra-low power consumption IoT scenarios like smart agriculture, smart office, and smart industry. It is designed with industrial standards with a wide working temperature at -40℃ ~ 85℃, high sensitivity between -116.5 dBm and -136 dBm, and power output between 10 dBm and 22 dBm.



    This Grove LoRa-E5 also can be run using CircuitPython programming language, suitable for students and beginners. For more information, check out these great videos from Sidik dot My on how to send AT command and perform point-to-point communication (P2P) using Grove LoRa-E5:


    Nowadays, the LoRa network has become very popular with the presence of Helium. For the time being, there are a total of 900,000 Helium hotspots around the world. So, with the huge amount of hotspots, coverage of the LoRa network should not be a problem anymore. Everyone can use the network for free without the need to ask permission from the hotspot owner. Therefore, this Grove E5 is one of the best devices to use with the Helium network. From our testing, we are able to get communication up to 24km using the Grove E5 and Helium hotspot in our office area. Figure below shows how the Grove E5 successfully sends data to the Helium console using the LoRaWAN network.
