Lora module is a kind of ultra-long distance, low power consumption, low frequency, high receiving sensitivity, and low cost wireless IoT equipment. It is also the most promising low-power WAN communication technology. Based on the RAK811 Lora module, an expansion board compatible with the Arduino development board can well evaluate the performance and characteristics of the Lora module.
General Description
RAK811 Low-Power Long Range LoRa Technology Transceiver module, provides an easy to use, small size, low-power solution for long-range wireless data transmission. First, The RAK811 module complies with the latest LoRaWAN Class A & C protocol specifications, it is simple to access LWPA IOT platforms, such as Actility etc. Second, it also support Lora Point to Point communications, this function can help customers implement their own private long-range Lora network fast. The module integrates semtech SX1276 and stm32L, offer user serials At commands with UART Interface. It is easy to accomplish their applications, such as simple long-range sensor data applications with external host MCU, low-power feature is suitable for battery applications. This compact module is a total solution that developing of LORA-wan protocol techniques.
