RFM98 LoRa Radio Node v1.0 ATmega328P 868MHz

Description

The LoRa Radio Node v1.0 is a purpose-built development board combining an 8-bit ATmega328P microcontroller with a Semtech SX1278-based RFM95 LoRa transceiver, optimized for the 868MHz ISM band. Its architecture provides a balance of processing capability and ultra-long-range, low-data-rate wireless connectivity, making it suitable for remote monitoring applications where Wi-Fi or Bluetooth range is insufficient. The board operates at 3.3V logic, powered either by the integrated 14500 LiPo cell or an external 3.7V to 12V DC source, with an efficient onboard regulator ensuring stable power for both the MCU and RF module.

Designed for system integrators and makers, the node exposes critical interfaces including dual I2C ports, analog inputs, digital GPIOs, and dedicated SPI lines for the radio, facilitating seamless connection with sensors, displays, and peripherals. The use of the standard Arduino Pro Mini 8MHz bootloader simplifies firmware development within the Arduino IDE, allowing developers to leverage extensive community libraries for LoRa communication (e.g., RadioHead, LoRa) and sensor integration. This board is engineered for reliable, battery-operated deployments in IoT networks, smart agriculture, environmental sensing, and asset tracking scenarios.
