Mounts like on the SX CPU flex would be advisable, reduces he risk of the caps being torn off from negligence or a hard fall etc

I subscribe to this as well, good point. Maybe just 1 ground point to attach to the metallic shell would be sufficient. This would ensure a robust positioning, and as well another GND point for the glitching.

I already thought about this but still looking for another way to proper mount cable into CPU surface than solder it into metal frame. But if there is no better solution, I will be back with SX cable way.

This is awesome work!
If I may, a couple of suggestions:

i) move the P15 (gate) test point to a different position, so it stays away from the metallic shell surrounding the CPU (less probability of shorts)

ii) change the "k" to "c" as requested on the other thread by rehius.

PS: loved the homebrew slogan

Yeah, I agreed with i) and I would like to move in to new position (below image)

For ii), after I read rihius comment, I have changed it and edit this post.

Thank all of you for your feedbacks/advices.

yes smaller, 32/34/36 awg are the most common I believe.

Welp, time to order more parts.

I cant find the exact mosfet in my country.
Will IRFH5300PbF do the trick?

tnx

Colleagues, I have a question. The only drawback by not placing the mosfet is that I won't be able to enter the nand, everything will have to be done from the emunand?

(On a side note, after having gone through this little exercise, I think I’m going to mount my mosfet dead-bug style so it will orient properly and look cool like the Erista chip…all side mounted with no wires going from mosfet to the caps.)

Might as well solder gate pin of mosfet directly to pin 15 of rp2040 and run 2 wires to cpu. Much cleaner tbh.

Not to mention it won't hinder with heatsink height clearance.

I think the connection from CPU to MOSFET should be short and with thick wires.

Enameled magnet wire is your friend.

Incorrect. The Mosfet is *REQUIRED*

you are thinking of the resistors, if you don't have them, then only the emunand will work

What are the requirements for the n-type mosfet? Same Vgs threshold + Id as the one recommended?

IRFSH8342 MOSFET is whats been recommended

colleagues, these 471 resistors are useful for the installation?

• 47-50 ohm resistors - SMD 08085 or smaller <---

thank you then you are fine
rookie question is the mosfet yes or is it mandatory?

mosfets are a mandatory, it's most crucial piece after the chip itself. The resistors are there to be able to boot HOS.

Wednesday I live in a third world country hahaha and of the ones mentioned here I can't find it, will it be some other different reference that you can inform us of?

Can you order for one of these?

Yes, I ordered them and they take about 3 months to arrive

another question after installing everything to enter atm it's time to launch a payload to start it with the pick you have to unlock something

Depends.

I would just get the PiCoFly FW2.5+unlock.uf2, then you don't need to do the manual unlock.

1-So the only file that I have to pass to the rp2040 is this and that's it PiCoFly FW2.5+unlock.uf2 is already soldering and assembling and that's it, with this cro emunand and can I enter both emunand and sysnan?

2-

And last question in case you have to update the sysnan you can without problem or there is some problem or is there something that one has to do separately
