lamaPLC: AI-Thinker LoRA products
Ai-Thinker's LoRa product line is divided into the Ra Series (SPI-based), which provides raw access to the radio chip for custom protocols, and the LoRaWAN Series (SoC-based), which includes an integrated MCU and pre-installed AT firmware for standard network connections.
| Product Series | Model | Frequency | Core Chip | Interface | Primary Use Case |
|---|---|---|---|---|---|
| Ra Series (SPI) | Ra-01 | 410–525 MHz | SX1278 | SPI | Low-cost DIY, spring antenna included |
| Ra-02 | 410–525 MHz | SX1278 | SPI | Point-to-point, external IPEX antenna | |
| Ra-01H | 803–930 MHz | SX1276 | SPI | High-frequency (EU868/US915) DIY projects | |
| Ra-01S/SC | 410–525 MHz | SX1268/LLCC68 | SPI | Modern replacement for Ra-01/02 with better efficiency | |
| LoRaWAN (SoC) | Ra-07/07H | 410–960 MHz | ASR6501 | UART (AT) | Integrated Cortex-M0+; standard LoRaWAN nodes |
| Ra-08/08H | 410–930 MHz | ASR6601 | UART (AT) | Integrated Cortex-M4; supports LoRaWAN/LinkWAN | |
| Ra-09 | 410–525 MHz | STM32WLE5 | UART/SPI | High-performance industrial IoT; multi-modulation support |
