Spirit Click Board™

Product Code: MIKROE-2568

The SPIRIT Click Board™ carries the SP1ML 868MHz ultra low-power RF module. The board is designed to use 3.3V power supply and 3.3V or 5V I/O voltage levels. It communicates with the target MCU over UART interface, with additional functionality provided by the following pins on the mikroBUS™ line: PWM, RST, CS. It can be used to wirelessly send and receive UART data. SP1ML 868MHZ RF MODULE FEATURES SP1ML is based on the SPIRIT1 RF sub-GHz transceiver (with integrated SMPS), STM32L1 microcontroller, integrated filter/balun, and chip antenna. There are two operational modes, command mode and operating mode. The command mode allows module configuration and status interrogation using an extended 'AT' style command set. In operating mode the module serves its primary purpose as a wireless transceiver. In operating mode the module uses only 13.5mA, 2.2mA in command mode, and even lower in standby with just 1.4µA. This kind of power consumption makes it ideal for smart devices that send small amounts of data.

The module has an integrated antenna and crystal.
