Description: 1. LoRa-Ra-01 is a long-range, low-power RF transceiver module based on the LoRaWAN™ protocol. It operates in the Sub-GHz ISM band (Europe: 862-870 MHz, US: 902-928 MHz). 2. This transceiver supports both LoRa and FSK modulation schemes, enabling long-range, low-power wireless communications for IoT applications. 3. The module features a simple SPI interface, making it easy to integrate with various microcontrollers, development boards, or other systems. 4. With its adjustable transmit power from 0 dBm to +20 dBm and receive sensitivity down to -148 dBm, LoRa-Ra-01 offers a high flexibility for different communication ranges and link budgets. 5. The compact module size of 22 x 20 mm (0.87 x 0.79 inches) makes it suitable for space-constrained applications like wearables, sensors, or asset trackers. 6. It features an onboard inverted IPEX antenna connector that can be replaced with external antennas to optimize range and directionality. 7. The module supports both standard LoRaWA
