Ai-Thinker Ra-08 LoRaWAN module features ASR6601 chip (Sponsored)

Ai-Thinker Ra-08/08H are new LoRaWAN modules based on ASR Microelectronics ASR6601 module featuring a 48MHz ARM Cortex M4 microcontroller and Semtech SX1262 transceiver allowing long-range, low power communication for the Internet of Things.

Both LoRaWAN modules share most of the same specifications, but the Ra-08 module operates in the 410-525MHz frequency band, while the Ra-08H module works in the widely used 803MHz to 930MHz band. Ai-Thinker also provides a development kit for each module.

      1. search github for ASR6601-getting-started-guide / akarsh98 / ASR6601-getting-started-guide
        I wonder if it’s possible to lock property coding using kind of flash security bits.
        Can’t find any info about it.
