  1. Like a esp32s2-esp32c6 combo, only a lot more expensive.. and without wi-fi support. If you really want to use pic, I guess this is your best choice.

  2. MC is out of stock on so much of its inventory. Not expected to get most stuff until 2024 they say. One would have to be crazy to even think to use anything from MC.
