Hello @F4HZA o/
I have not tested the Revision S yet - this is the reason that I didn't promote it to the Main branch.
After consulting my digikey and JLCPCB orders, I found that I ordered the parts but never ordered the board - last known good revision is R.
When I get back to São Paulo (I'm in holidays here) I'll check my parts inventory and if all is sound, order a new board revision.
Side note, I found that this BFR193F is... tiny. Will be a pain to solder it; the 2SC5086 was already a challenge.
You might also want to check this reddit thread where I was suspecting that the BFR193F wasn't a suitable choice (spoiler alert: it seems it was the right choice).
Expect to have the Rev. S tested by mid March. Will keep this issue open for the time being.
