I have a v3 pico that’s stuck in a reset loop. What’s odd is that it lights my strips through the expander on three reboots before looking like it’s just “stuck.”
Prior to reaching this state, I had configured them in STA mode to light the two strips through the expander, and it seemed to work. The power supply is a little thin (5v, 0.3a), but it’s only powering the pico and expander. The strips are getting 12v that’s powering the 5v supply.
Edit
I slapped a much larger 5v supply on, and it’s happy, now. The problem is always brownouts, lol.
