PSU-Plus Official Release

Everything you need is on the github page: https://github.com/CrazyGadgetMods/PSU-Plus

ah. thanks, i see it
the last time i built a sega megadrive portable, the parts were listed on github in plain text but this time it's in the BOM file which i just discovered enables the user to upload it to digikey and list all of the components in your basket automatically. that's awesome

If you want to order from PCBWAY it gives you a problem with the bottom mask, so with the permission of CrazyGadget I made a fix,

Again CrazyGadget thanks for an amazing job with this project

thanks for the fix, but one issue i had--
PCBWAY noticed that the gerber files you provided had an empty bottom mask, and a copy bottom mask that was centred in the wrong place

i'm hoping my little adjustment has sorted the issue but i'm not a professional at this so it might not be accepted by PCBWAY

i'm hoping this one will be accepted

i don't really know what i'm doing. i'd appreciate it if you could help me out, if possible. thank you

If you're not sûre of what you are doing, you can just buy it at the etsy's shop of @CrazyGadget.
Hope it's useful!

got lucky and the altered gerber file i sent PCBWAY was accepted and it is now in production.
i already have all of the parts required to solder to the board. will post a photo when the pcb's arrive - i wanted to turn 2 of my wii's into micro wii's, an RVL 01boot2, RVL 50 and a third wii with a power bank installed into the case to make it into a portable without RVL-PMS-2, so it would have been very expensive to order 3 pre-assembled boards at full price

thank you, crazygadget and pcbway

managed to successfully get 6 out of 10 working correctly. 3 of them have a few faulty outputs, some of them outputting 10v on a few lines, so i'll have to take a look and sort it out at some point. experimented with one of the boards by using solder paste and hot air rework station but that ended up damaging a few traces and ripping them from the board

it took forever to do all 10 of these manually with a microscope and soldering iron. i now understand why they are priced accordingly. i appreciate it, crazygadget

this is the first time i've used a microscope and attempted micro-soldering
only need 3 of these boards so this is a win


next time i'll order a stencil

Ive assembled complete board but it is not doing anything are there any measurement instructions so i can troubleshoot it?

Hi

I have made a custom circuit with the psu plus components for a 6 layer wii but I have a little voltage drop when I connect a wii on the 1v and 1.15v rails than probably make the wii cannot boot:

Idle:
1v: 0.97-0.98v
1.15v: 1.12v

On load:
1v: 0.92v
1.15v: 1.08v

I have ~1amp current on this rails and I have the same issue with 14 10ohm resistors for a consumption around 1.5amps so the regs are the issue.
I have already remark the inductor pads are not the same than on the image because I use easyEDA and I used the components in the library. Can be this the issue?
There is the design screen captures:

The 1.8v, 3.3v and 5v rails have good voltages (1.76v, 3.26v and 4.98v all on load, tested with the wii connected)
Note: U2 is an ATtiny1616
Can you help me please?

Hi I had exactly the same issue I was using a layer 6 board very first rvl 01 model did another trim with a rvl 20 Wii and the body plus worked. Maybe the rvl 01 Wii consumes more.

The PSU Plus is designed to support the higher power draw of 6 layer Wiis, but it is possible that you both got bad silicon that doesn't like the normal 6 layer voltage drop.
The simplest solution I believe would be to adjust the RSET resistor value to raise the nominal output voltage of the 1v and 1.15v lines. A typical Wii can handle around +5-10% voltage without issue, so raising 1v to 1.05 and 1.15v to 1.20 might just get you over the line.

The equation to figure out what resistors you need will be in a table in the regulator's datasheet.

It can be my design that is wrong ?
I replaced all the components with new because I bought a lot of each but no my inductor but the issue persists...
Thanks for your response. I’ll determinate the resistors as soon as posible and post if that work
EDIT: I calculated 5 and 3,125 Kohm resistances. It's good?
