Excellent there will likely be some great developments! Have you already considered using a single FPGA to handle everything?

Great job! I'm really happy to see that work on the PS2 is still ongoing, and it looks like the goal of creating an ultra-minimal board is very close—congratulations! Also, I see something very “familiar” is the chip a GW2AR-LV18QN88C8/I7? It would be the same one used in the Tang Nano 20k...

Interesting, and a nice bit of progress! Regarding the BIOS, can it completely replace the original chip, or as shown in the photo does the RP need to operate in parallel and send data, similar to a Modbo chip?

Hi, it should be salvageable. Are you sure you checked all the fuses marked PS and TH? Also, check the voltage between the input and output of the 7805s.

You can easily do it; I did it with a 70004, so it’s even better with a 7900X since it has lower power consumption.

Hi, latest update: Since I didn’t want to stick with the 802, i was sorting through my stuff and dug up the TLV62095RGTR I’d originally used on my PS2P, so I figured I’d find it a "new home", even though it might not be the best application given the low load. Using a small inductor and...

Look, pretty much anything is possible, but we have to be realistic: using a power bank module to convert the 4.2V battery output to 5V—and then generating all the necessary voltage rails from that—creates a fundamental issue. Will it work? Yes. But you’ll face serious problems with heat and...

https://bitbuilt.net/forums/threads/bestiolino-nano-full-new-power-management-system-open-source.7386/ Hi, it depends on whether you want a custom, semi-custom, or completely independent solution. The custom approach would be to use an already polished PMS (Gman's v1, v2, or v2 Lite); I was...

https://it.aliexpress.com/item/1005008804243283.html That post is too old; I suggest you start your own work log—you could try using the shared one. Please note that it is indicated for 1 lithium cell and not 2.

Unfortunately, yes—you absolutely need to clear that direct short circuit. If you can replace the LDO with a small regulator, that’s not a problem; we can find a solution, assuming that turns out to be the issue. Of course, first try to determine if the traces themselves are shorted by sanding...

One final test is to remove the LDO completely—it might well be the culprit; if you have a bench power supply, you can apply voltage to see if it heats up.

Check that solder ball on the 1.8V LDO.Check that solder ball on the 1.8V LDO; it could also be the regulator itself. Try desoldering it and taking the measurement again.

Hi. No, I meant for all voltages from 5V down to 1.8V; besides not being able to operate at 1V, it wouldn't have the necessary current (that module has a tiny inductor anyway, so I wouldn't exceed 500mA for 5V in buck-boost mode). For lines below that voltage, look for that green module on...

Hi guys, here are a few updates on the modifications (I hope the post isn't too old to be updated) lol: A new PMS—a variant of the PS2 "bestiolino" for the Wii—following the same logic; it simply lacks the second regulator for the 5V and 2.5V rails. While it could have been even smaller, the...

YveltalGriffin gave you a practically perfect list; I’ve used and tested quite a few of them for the same purpose. If you want to save money, the TPS63802 module is practically perfect for 3.3V—and potentially 5V if the load is low (like for an SD card or LCD). You can even use it for 1.8V (the...
