Thanks for this.
The trim allows you to use custom regulators so that you can use a < 12V input, and of course that will slightly improve efficiency but for a 6 layer board you can still expect around a 15-20W power draw.. It's best to just pick up a 4 layer since the Wii board itself is only around 10 dollars if you look in the right places, and there are methods to select 4 layer boards without looking at them.I have an OLD wii (-01 motherboard, I still have the box as I was like 141st one sold in US) so I assume power consumption will be high, closer to 20W then 10W of a -30 or newer board. But what effect on this does the OMGWTF 6layer trim have? obviously the wifi module, power and temp safety components, and Disc Drive get axed... but I'm running a 5" LCD&Driver off 3.3v and the speakers as well, what should I expect as a total draw??
Because of the above, I'm wondering what sort of deliverable voltage should I plan for? is a 2S2P of 18650s acceptable/standard?
It would give me 7.4v and around 7Ah which seems like aprox. 2 hrs of charge (7x7.2)/(20W)*.8 with .8 being my accounting for non-perfect discharge/charge conditions and battery imperfection. Is the 7.4v required for running a Wii board? or could I get away with 1s2p?
I have batteries picked out:THESE
and a CMB, but I'm concerned on this one..., as it requires a 9-15V in for charging. I'm wanting to be able to charge off of my same power adptr as my Cellphone (USB-C 5v 2a) so I'm wondering what if any solutions the community has come up with to push a charge to a 7000mAh bank? I noted the all-in-one power management boards on the bitbuild store, but that's fairly costly given the alternatives in the wild. Not to mention I'm in no shortage of components to draft up my own PCB, just not the most skilled with power electronics
yikes! the cost for those two boards together is around $120USD.. thats almost twice what the entire rest of the project has cost me. ill stick with the red CMB i linked and a 12v wall-DC power supply, it may not be as convinient for portability (haul extra charger around) but its only going to cost $11 vs $120.I would suggest you use the USB C board alongside the Wii PMS from the bitbuilt store which is an all in 1 solution to regulators and battery management. The USB C board with the PMS natively supports USB C PD to charge at much higher.
With this board could you hot plug the DC jack without console reboots?Ok thanks, that makes sense. This photo is what you mean?
The Raspberry Pi is very simple to use with batteries as you can simply power them from all the parts found in a cheap battery bank. Using components like the ones you listed will only complicate a portable Pi build.Hello, I'm very new to portabilizing and have a few questions about batteries.
I've read over the Portables and Batteries: A Guide and Explanation post many times, and was considering using the 2s CMB recommended (https://www.ebay.com/itm/311721987212) for my raspberry pi 3B+ portable. Though I had some questions on things like, can I attach an on/off switch to it, how exactly do I connect the batteries to it, is there a specific charge port I should use or can I just use say a USB-C port. This will be my first ever portable, so I'm not sure about a lot of things. Any help would be nice.
