The SFBLE01 is a SIGFOX Monarch and BLE module. It suports all global Sigfox regions besides BLE 4.2. Suitable for using as a SIGFOX/BLE modem, communication through UART interface (CLI/AT commands), as well as the main application processor embedding the user code in its onboard MCU.

SFBLE01 module is a cost-effective, high performance, low-power solution to be used in a widerange of products. It presents very low current consumption both in active and low-power  MCU modes providing excellent battery lifetime and allowing for operation on small batteries and in energy harvesting applications.
