Boardoza RA-01S-P LoRa Transceiver Breakout Board
Boardoza RA-01S-P is a LoRa Transceiver Breakout Board based on the Ai-Thinker Ra-01S-P module, a bidirectional level shifter, and a low-dropout (LDO) linear regulator. It allows microcontrollers (Arduino, STM32, ESP32, Raspberry Pi, etc.) to communicate over long-range LoRa networks via a standard SPI interface. The module is widely used in IoT networks, remote environmental sensing, smart agriculture, and robotics telemetry applications. The Ra-01S-P module handles the integrated LoRa communication and RF packet conversions, while the level shifter translates the logic signals safely to match the host microcontroller's I/O voltage levels. With the Boardoza RA-01S-P module, you can deploy long-distance wireless links easily.
Key Features
- Chirp Spread Spectrum (CSS) Modulation: Leverages the high-sensitivity, ultra-long range Ai-Thinker Ra-01S-P module with SX1268 core.
- High Output Power & Sensitivity: Achieves an impressive +29dBm maximum transmit power and a high sensitivity down to −137dBm (@SF10, 125KHz).
- Spreading Factors: Fully programmable across SF5, SF6, SF7, SF8, SF9, SF10, SF11, and SF12.
- Onboard Logic Level Shifting: Integrated level shifter translates SPI and GPIO logic between the host system and the 3.3V module.
- External Antenna: ANT pad for direct, RF coaxial wire.
