Beware those TXS0108 translators. They don’t like bus capacitance and won’t work well between a flash cart and the VB. You’ll have no end of problems. They’re meant as bidirectional translators for on board chip to chip applications, not for signals that go off board.
Very nice sir!
My only comment is you probably want to use translators instead of just inline resistors. There’s a reason most of the flash carts use the 245 translators chips and they’re only a couple dollars each. The concern is on the STM32 side. The VB input should work at 3.3V logic.
And if you haven’t already, you’ll want to sign up for the Discord channel. Most activity is there these days.
Here’s the latest clear cases. Given how long this has dragged out, and that I think new shells are coming later this year from a couple sources, I’m going to stop my work on this. My mold guy wants to make molds but isn’t so interested in producing the actual parts. Given all my other projects, I’m pausing this one.
