## Description

**SigFox Module** is a universal wireless module suitable for SigFox communication and Tracker equipment in the COM.X series. The module is based on the SFM11R3 chipset, with the AX-SFJK-1-01 internal RF chip.

The transmission frequency is 923.2 MHz, receiving frequency is 922.2 MHz, and the bandwidth is 192KHz. In order to allow the user to modify the configurations of  pins, the DIP switch is used to set the hardware serial port pins.

The user only needs to switch the corresponding pins to ON and specify the pins in the program. A DC power socket is designed under the module, which can be powered by an external power source.

>COM.SigFox RXD/TXD can be connected to M5Stack's UART (TX(0/13/17)RX(5/15/16)) by setting the DIP switch. Since these GPIO in **M5Stack Fire** 16/17 are connected to PSRAM by default. It is recommended to use any set of UART pins in the remaining two groups.

>The DIP switch on the right is invalid for the LoRaWAN module, no need to set.

 ## EasyLoader

>EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification. Please install the corresponding driver according to the device type. M5Core host [Please click here to view the CP210X driver installation tutorial](en/arduino/arduino_development), M5StickC/V/T/ATOM series can be used without driver)
