MiniF27：500mw LoRa Wireless transceiver module
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 switch is internally controlled by the chip, reducing the resource demand on the external MCU. Despite its ultra-compact size (same as the LoRa1262), the MiniF27 delivers an output power of up to 27dBm (500mW). Its high integration, small size, and high power make the MiniF27 highly advantageous in IoT and battery-powered applications.
MiniF27 strictly uses lead-free technology for production and testing, and meets RoHS and Reach standards.
