Looks really interesting. If only they were available...

LCSC has some new Padauk MCUs in stock: The PFC161 in various package types. The price is not interesting at all, though (>$0.30).

KaeTo:
Hello,

can anyone tell me where you can buy Padauks (PFS154 and PFS173) right now? I used to buy them at LCSC, but they are out of stock since months. Does anyone knew an alternative platform or when LCSC should have them in stock again?

LovelyA72:
It's kinda quiet here...

I am currently trying to make audioplayer work on a PFS154.
However, the example does not work at all. After probing on the SPI line I found that not only the timing is a mess, the padauk is driving the MISO pin which it needs to be listening to instead of driving.

I am wondering this might be a compiler issue since I can't see any pin manipulation on the MISO pin.
