M5Stack COM.LoRaWAN Module 868MHz V2.0 (ASR6501)

The

M5Stack

COM.LoRaWAN868 v2.0 is a LoRaWAN communication module suitable for 868MHz frequency.

The module adopts the ASR6501 scheme, which supports long-distance communication and has high sensitivity characteristics. The module integrates the LoRaWAN protocol stack, adopts the serial communication interface (using AT command set for control), and can be used as a collection node for a large number of access gateways for data collection management.

This module is suitable for long-distance low-power IoT communication applications, such as the deployment of environmental monitoring nodes.

Notice

• When used with a

  FIRE main controller

  , due to the PSRAM pin conflict, please switch the DIP switch pins of the module base to TX(0/13), RX(5/15), and the device can use USB/ External DC is used for power supply.

• When used with a

  Core2 series main controller

  , due to the different order of the base pin array, COM.X base pins TX(16), RX(17) correspond to the actual pins TX(14), RX of the Core2 main control (13) The equipment needs to use external DC for power supply.

The module base has a DC power input interface. Please strictly follow the input range (5-12V) to prevent damage to the module when using this interface to connect to the power supply. The internal power DIP switch can adjust the voltage level of the internal terminal VIN to adapt to different modules.
