M5Stack: LoRaWan 868 MHz Unit (ASR6501, UART), Grove

LoraWan 868 Mhz (ASR6501) unit with Antenna - grove Serial/uart

Here is the Grove Unit LoRaWAN868 made for the LoRaWAN communication at European frequency (868MHz). This module from M5Stack uses the ASR6501 chipset to support the LoRaWan transmission. The module supports long-distance communication with ultra-low power consumption (and still high sensitivity).

The chipset ASR6501 integrates the LoRaWAN protocol stack and communicates with the host via a serial/uart interface (at 3.3V logic, using the AT commands). This module can be used as transmission node for a data collect device (remote management). It can access a large number of gateways.

This module is suitable for a for long-distance low-power IoT communication applications. Applications can be: deployment of environmental monitoring nodes, automatic remote meter reading,  Remote irrigation monitoring.

The Unit LoRaWan868 offers a good and reliable communication layer thanks its external antenna.

This product requires a microcontroler to work.
