Ai-Thinker LoRa Ra-01S
Description:
Anxinke LoRa series modules (Ra-01S) are designed and developed by AnxinkeTechnology. This module is used for ultra-long-distance spread-spectrum communication. Its radio chip SX1268 mainly uses LoRa remote mode for ultra-long-distance spread-spectrum communication. It has strong anti-interference and can minimize current consumption. With SEMTECH LoRa patented modulation technology, SX1268 has a high sensitivity of over -148dBm, a power output of +22dBm, a long transmission distance, and high reliability.
At the same time, compared to traditional modulation technology, LoRa modulation technology also has obvious advantages in anti-blocking and selection, which solves the problem of distance, anti-interference, and power consumption that traditional design solutions cannot simultaneously take into account. Application areas are used in automatic meter reading, home building automation, security systems, and remote irrigation systems.

How to Use Ai-Thinker LoRa Ra-01S
To get started, solder the Ra-01S module onto your PCB via its SMD16 footprint or attach an antenna to the half-hole/through-hole pads or IPEX connector. Connect the module’s SPI pins (MOSI, MISO, SCK, NSS) and control lines (DIO0, RESET) to your microcontroller, then configure LoRa parameters (frequency, spreading factor, bandwidth) in your firmware. Power up the module at 1.8–3.7 V, and initiate transmissions or reception using standard SX1268 register commands.
