LoRaWAN MCU

Cquk

Hi All

Looking for recommendations on a low power LoRaWAN MCU ie radio and processor in a single package. 

Cost is of course an issue. I really need sub 5 USD.

Thanks

  • Ai-Thinker RA-08H is very low-cost. It's $5.14 in quantity of 1250 on the Digikey website, but it's cheaper even in individual quantities from places like AliExpress, so I suspect you could get it for a far lower price from China.

    Internally, they contain a ASR6601 wireless microcontroller, which has a STAR-MC1 processor, which is closely like an ARM Cortex-M, but is a Chinese variant. Toolchain is available for Linux, with plenty of examples.
