It should be 4k7 To measure it you must first remove it from the board.
Yeah, the point comes out just next to the ram, makes it ideal to run an insulated wire through the opening in the metal enclosure. Just makes sure if you use enamel wire not to let it expose the wire on the sharp edges of the enclosure from movement, I use a thin silicon insulated wire from Adafruit.

Yeah. I see now that 4k7 is the right value. but with 10k works fine. let hope continue that way.
Here is a rp2040 + dual mosfet board, it's untested at the moment, I'll get back to to the thread once my boards have arrived.
It measures about 14mmx 25mm from memory. If you order the board with 0.8mm fr4(economical) the total height is around 1.7mm, otherwise with 0.1mm flexible polymide the total is about 1mm.

Just curious, looking at the layout, where does the "dual MOSFET" come in? I only see one component in the renders that appears to be a MOSFET.
Ahhh! Thank you for the clarification! Admittedly, I've been drinking, since it's an American holiday.
You may have just inadvertently shown me the new mosfet package which I should do any future installs with, so thanks for that!
Have you tested it ? seems the RdsOn value is too high, or maybe it can only work with SDA SCL point.
My one cent guess (based on hunch from experience). It might working.
I have been longtime doesn't regard datasheet measurement as accurate. Different manufacturer different measurement. Its TI different then AON or IRF.
I haven't tested it. The rdson value is well within scope. It is only 3mΩ higher with a of VGS = 4.5V. I = (assuming 1.8v across cap, just a guess) / 0.00002 ohms = 90,000amps vs i = 1.8 / 0.000023 = 78,261amps, negligible for an application that is tdp using 2 amps at max ever.

It might not work. I still not yet getting confirmed from someone using TI mosfet.
The characteristics of IRF and AON in this glitch are well tested.
Not yet tested the TI mosfet.
After flashing, shouldn't be an issue. Also, recommended that you stick with most up-to-date firmware from Rehius here

The first time i mod, i remove the LDO, afraid that the height is not enough.
After that i don't remove it, since the height are enough.
And if the usb somehow need to be soldered (to upload firmware), i don't need to place that LDO again.
Yes

I don't think you quite understand how small the difference is between these mosfets is, I put my money on it working.

@Xdqwerty, Osu! Tatakae! Ouendan! is the Japanese version of the game, different settings/characters/songs but otherwise identical mechanics. I played that before I knew about Elite Beat Agents lol. Both fantastic games https://en.wikipedia.org/wiki/Osu!_Tatakae!_Ouendan+1 -
