I've been seeing posts semi-recently from people building BlueSAABs, yet the RN52 seems unobtainable for the last few months. How are people finding these? Everywhere you can buy them from is saying none will be available until 2023. Are there any bluetooth devices I can buy and strip it from them? Or is there some other alternative that will work well enough? It's between building this or buying the CDConnect adapter but it sounds like the BlueSAAB is of higher quality so would really like to build it.
