www.nicerf.com MiniF27 NiceRF Wireless Technology Co., Ltd. Rev 1.2 sales@nicerf.com -3- 1. Descriptions MiniF27 wireless module is designed using Semtech's LoRa chip, featuring a high-precision crystal oscillator,ultra-low receiving and sleep currents, and a sensitivity of -148dBm. It can wake up the microcontroller periodically while maintaining low power consumption. The module's antenna switchisinternallycontrolledbythechip,reducingtheresourcedemandontheexternalMCU.Despite its ultra-compact size (same as the LoRa1262), the MiniF27 delivers an output power of up to 29dBm (800mW). Its high integration, small size, and high power make the MiniF27 highly advantageous in IoTandbattery-poweredapplications. MiniF27strictlyuses lead-free technology for productionand testing, and meetsRoHS and Reach standards.
