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.

Spec Sheet

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

Technical Specifications:

• Model: Ra-01SH-P
• Package: SMD-16
• Size: 17*16*3.2(±0.2)MM
• Frequency: 803MHz~930MHz
• Operating Temperature: -40℃~ 85℃
• Storage Temperature: -40℃~ 125℃, < 90%RH
• Supply Voltage: 3.0~3.6V (typical 3.3V), >1A

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.
