Description Boardoza RFM6601W LORA Transceiver Module is a LoRa wireless communication breakout board based on the HOPERF RFM6601W module. It integrates a LoRa transceiver, RF transmitter/receiver, and a 32-bit ARM Cortex-M4 RISC microcontroller operating at 48MHz. The module supports 3.3V to 5V input and communicates through a UART interface, making it suitable for long-range, low-power wireless applications such as IoT sensor networks, smart agriculture, industrial monitoring, and remote telemetry systems. Important: Always connect an antenna before powering the RF module. Operating the module without a connected antenna may cause RF stage damage and significantly reduce transmission performance.
