The ATTiny inventory at LCSC is pretty much all wiped out. ATTiny45 and ATTiny85 specifically. Looks like there's new parts under the "Pre-ordered MCU" category. But no stock of them, and the price of those parts is much higher than MSRP/other retailers, and significantly higher than the old part numbers at LCSC. What is going on with this ATTiny inventory? When can we expect the new parts to have stock, and at the old pricing?
