yes, resistor only to avoid noise.
should we use a pull-down resistor on the G when installing MOSFET directly
to the APU?

As described by @SQc04:
"The pull-down resistor keeps the gate of the FET low in the default state,
and if there is no resistance, the default state of the gate of the FET is
high-impedance, which may cause the FET to be turned on until it burns.
The resistance value of the pull-down resistor is about 1~10KΩ"

It sounds reasonable and hwfly cable has this resistor AFAIK.

Or maybe your fw pulls-down it programmatically?

firmware has a pull-down. even without a pull-down (firmware startup period), rp2040 acts as a very weak pulldown

What about using a pull down resistor something like 10k ohm to the ground before 47 ohm maybe it Will fix the noise?

Yep, thats the same with what i think about how mosfet works with pull down resistor to the ground

Switch lite pico fly
1.flex cable v2
2.smd resistor 47R and 20R
3.pico fly Rp2040 chip
4.wier flux tools soldring.
Digram for lite motherbord.
Hi everyone, I am new to this theme, can someone please tell me what I need to buy to install picofly on my switch lite? (links to the components used and some sort of tutorial are welcome)

Hey guys, long time lurker first time poster. Finally did the mod, it glitches and boots Hekate fine. Using 51ohm resistors because I read somewhere that Toshiba eMMC's prefer a higher resistance. I ran the picofly unlocker payload and all that and it said it flashed successfully.

Anyways, I get this error anytime I try to boot Stock or EmuMMC. I'm also seeing that my secure boot key is all F's and my Cal0 is corrut.
I got this error to but you can backup boot0/boot1 first from hekate the restore the backup again coz it's work for me

  • No one is chatting at the moment.
  • JuanMena @ JuanMena:
    Will you give me mouth to mouth oxygen if my throat closes?
  • K3N1 @ K3N1:
    Nah the air can do that
  • K3N1 @ K3N1:
    Ask @x65943 he's trained for that stuff
  • JuanMena @ JuanMena:
    Kissing random dudes choking in celery? Really? Need to study for that?
  • K3N1 @ K3N1:
    Yes it requires a degree
  • K3N1 @ K3N1:
    I could also yank out the rest of my teeth but theirs professionals for that
  • x65943 @ x65943:
    If your throat closes, putting oxygen in your mouth will not solve anything - as you will be introducing oxygen prior to the area of obstruction
  • JuanMena @ JuanMena:
    Just kiss me Kyle.
  • x65943 @ x65943:
    You either need to be intubated to bypass obstruction or create a stoma inferior to the the area of obstruction to survive
  • x65943 @ x65943:
    "Just kiss me Kyle." And I thought all the godreborn gay stuff was a smear campaign
  • JuanMena @ JuanMena:
    If I die, tell my momma I won't be carrying Baby Jesus this christmas :sad::cry:
  • K3N1 @ K3N1:
    Smear campaigns are in The political section now?
  • JuanMena @ JuanMena:
    Chary! Chary! Chary, Chary, Chary!
  • Sonic Angel Knight @ Sonic Angel Knight:
    Pork Provolone :P
  • Psionic Roshambo @ Psionic Roshambo:
    Sounds yummy
  • K3N1 @ K3N1:
    Sweet found my Wii u PSU right after I ordered a new one :tpi:
  • JuanMena @ JuanMena:
    It was waiting for you to order another one.
    Seems like, your PSU was waiting for a partner.
  • JuanMena @ JuanMena:
    Keep them both
    separated or you'll have more PSUs each year.
  • K3N1 @ K3N1:
    Well one you insert one PSU into the other one you get power
  • JuanMena @ JuanMena:
    It literally turns it on.
  • K3N1 @ K3N1:
    Yeah power supplies are filthy perverts
  • K3N1 @ K3N1:
    @Psionic Roshambo has a new friend
    +1
  • JuanMena @ JuanMena:
    It's Kyle, the guy that went to school to be a Certified man Kisser.
  • Psionic Roshambo @ Psionic Roshambo:
    Cartmans hand has taco flavored kisses
  • A @ abraarukuk:
    hi guys
