The Ra-01SH-P is a LoRa (Long Range) series module designed for ultra-long-distance spread spectrum communication. Developed by Shenzhen Ai-Thinker Technology Co., Ltd., this module utilizes the SX1262 RF chip and LoRa™ modulation technology to achieve robust and reliable wireless communication over extended ranges. It’s ideal for applications requiring long-range connectivity with minimal power consumption.
Key Features:
- LoRa® Modulation: Employs SEMTECH’s patented LoRa™ modulation for superior range, anti-interference, and power efficiency compared to traditional modulation techniques.
- Frequency Band: Operates in the 803MHz ~ 930MHz frequency band.
- High Output Power: Configurable transmit power, up to +29dBm (with 3.3V PA supply) or +31dBm (with 5V PA supply – requires BOM modification).
- High Sensitivity: Receiving sensitivity as low as -137dBm @SF10 125KHz.
- Compact Size: Small form factor (17*16*3.2mm) with a double-row stamp hole patch package for easy integration.
- Flexible Antenna Options: Supports multiple antenna installation methods, including half-hole pad, through-hole pad, and IPEX connector.
- Low Power Consumption: Low receiving current of only 16mA.
- SPI Interface: Uses a standard SPI interface for communication with a host microcontroller.
- Data Packet Engine: Supports CRC and up to 256-byte data packets.
- Spreading Factors: Supports SF5/SF6/SF7/SF8/SF9/SF10/SF11.
Typical Applications:
- Automatic Meter Reading
- Home/Building Automation
- Security Systems
- Remote Irrigation Systems
- IoT Devices

Important Considerations:
- ESD Sensitivity: This module is ESD sensitive and requires proper handling precautions.
- Antenna: Requires an external antenna. Ensure the antenna is properly installed and positioned for optimal performance. Avoid placing the antenna near metal objects or inside a metal enclosure.
- Power Supply: Use a stable 3.3V power supply with a peak current above 1A. Ripple should be controlled within 100mV.
- VCCPA Configuration: The module’s PA is powered by the 3V3 pin by default. For +31dBm output power using a 5V supply, contact Ai-Thinker to modify the module BOM.
- Software: Operates based on the SX1262 chip manual.
