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.
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.

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.
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.
