COM.LoRaWAN470

SKU:M031-C2

Description

COM.LoRaWAN470 is a LoRaWAN communication module suitable for 470MHz frequency launched by M5Stack. The module adopts the ASR6501 solution, which supports long-distance communication and has both ultra-low power consumption and high sensitivity. The module integrates the LoRaWAN protocol stack and adopts a serial communication interface (using AT command set for control), and can be used as a collection node to access a large number of gateways for data collection and management.

An external power supply is provided (5V-12V input can be adjusted by switching the dial on-board switches). The module fits for long distance low power IoT communication applications, such as deployment of environmental monitoring nodes.

Notice

When used with the FIRE main control, 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 Core2 series main control, 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.

M5Stack FIRE GPIO 16/17 is connected to PSRAM by default. If the TXD/RXD of this module uses GPIO16, GPIO17 will conflict with it. Therefore, when using M5Stack FIRE to drive the module, you need to switch the DIP switch to any one of the remaining two sets of pins.

According to the different needs of different hosts, the DIP switch fluctuates to the corresponding pin.
