This week, LCSC electronics supplier Ai-Thinker shared an introduction to their LoRa module. The article will provide the basics of the LoRa module and Ai-Thinker’s featured products.
Due to its ultra-long transmission distance and low power consumption, LoRa technology has broad application prospects in the Internet of Things. LoRa technology finds widespread and successful applications in many fields, such as smart buildings, intelligent industrial parks, asset tracking, smart agriculture, and livestock management.
Ai-Thinker has a wide range of LoRa series, LoRaWAN series, LoRa gateway, and other products.
Introduction to the Ai-Thinker LoRa Module
LoRa is a wireless communication technology developed by Semtech that can propagate farther than other wireless methods under the same power consumption conditions. It is a new communication technology that can achieve long distance, long battery life, low power consumption, high sensitivity, large system capacity, and broad coverage.

Main functions and parameters
Power consumption/acceptance sensitivity
The Ra-08 module has a transmit power consumption of 115mA at full load, a maximum transmit power of +22dBm, a receiving working current of 6mA and a sleep mode of 1.3uA. Additionally, it has a receiving sensitivity of -138dBm, making it capable of operating normally even in complex interference environments.
The Ra-08H module has a transmit power consumption of 115mA at full load, a maximum transmit power of +22dBm, a receiving working current of 9.5mA and a sleep mode of 1.3uA. Additionally, it has a receiving sensitivity of -138dBm and strong anti-interference ability, allowing it to operate in complex and interference-prone environments.
Antenna form
The Ra-08 and Ra-08H modules are compatible with various antenna connection methods, including half-hole pads, through-hole pads (requiring soldering), and IPEX sockets. They also support multiple solutions for antenna selection.
Communication distance
The transmission distance of Ra-08 and Ra-08H modules with suction cup antenna is about 4.8km.
Network access method
These modules support two network access methods: OTAA and ABP.
Accessible to the ecosystem
The Ai-Thinker Ra-08H module can connect to TTN servers to facilitate data sending and receiving.
LoRa Gateway Series RG-02
RG-02 is an indoor LoRaWAN gateway. It supports Semtech packet transponder and LoRaWAN base station functions and is compatible with the standard LoRaWAN protocol. It adopts mainstream LoRa modulation and demodulation chip solutions (high-frequency version: SX1302+2*SX1250, low-frequency version: SX1301+2*SX1257). Additionally, it supports ten programmable parallel demodulation paths.
The gateway supports Wi-Fi, Ethernet, and 3G/4G cellular network access. We can deploy it to various application sites. RG-02 is preset with multiple standard LoRaWAN frequency band options, which can adapt to different countries and regions. It also supports user-defined frequency bands to build private LoRa networks.RG-02 can communicate with ABP LoRaWAN end nodes without a LoRaWAN server. The lightweight deployment method is very convenient for system integrators to directly connect it to existing IoT applications without building a LoRaWAN server or using a third-party LoRaWAN Serve.
