That's why I was thinking a teensy to handle the buttons and the analog stick. If a pi3 is used, no need for a usb hub.

The pi3 covers wifi and bluetooth, the usb at the top can go right to one of the pads along with the teensy.

@kite @Helder @Camble
Just wanted to say thank you for all the help getting this going. I knew almost nothing about PCB design a month ago, and you guys gave some great guidance.

@johnweland
Thanks for being the middle man and finding me the help I needed. It's you and a few dozen others that convinced me to make these.

@othermod Glad to be of help, even if in a small way.

Dude anytime, I'm stoked to see the project come along and hell one day actually start making stuff myself.

So after building the first prototype I really want to add battery control to the board. Having to stretch wires across the board for the 5v and GND to and from the banggood module, + and - from the lithium battery, power LED, low battery LED, and charging LED just sort of ruins the whole simplicity aspect I'm going for. I've already done the research on the charging portion, and that would eliminate all of the indicator LED wires and charging + and -, but something is still needed to boost the lithium to 5v (or 5.1v preferably).

I know it's been mentioned that a few of you were working on some schematics that have similar capability as the banggood.
Just hoping someone has found a cheap 1-2A boost circuit I can add. Anyone want to share?

I can always use something like this to do the boosting if need be, and 4 wires is way better than what I've got right now.

Hi.

I just brought your version 4 board, cant wait to get it shipped to me and getting started building it :-)
From what i understand you are not gonna sell these kit's anymore in the future.
I was wondering if you are gonna release all the schematics as opensource in the future maybe??
If you do i would be awesome to try to convert it to use a Raspberry pi CM3 module

I don't have the schematics in a sharable format for v4, but the PCB and BOM are available.
https://othermod.com/pspi-v4-pcb-and-schematic-files/

I'm doing a rework of the board to lower the number of components and simplify some of the circuits, and that schematic is open source. Once I finish shipping the v4 boards, I'll have more time to work on it. Here is v4.2 or v5 or whatever I'm going to call it:
https://easyeda.com/adamseamster/pspi-4-pcb-2
That schematic is far from being functional, but a lot of the individual circuits are complete. I won't be shipping this new board, and I'll leave it to others to build and sell.

A CM version is possible, but it might be some time before I have time to design it.

Nice of you to share it here with us.
I will take a look at tomorrow when i got more time
I was wondering if this display (https://www.aliexpress.com/item/4-3-inc ... 47542.html) can be used instead out of the box so it will have 800*480 Pixels

Hello everyone,

After some time working on the project of Othermod, several tests more or less successful, I decided to build and distribute this project.
My long post was refused for :

"Reason: The reported message has the only purpose to advertise for a website or another product.."

I hope this one will not be refused...as i don't talk about money or any website?
This was just to say that this project will continue...

Neslou.

Thank you for accepting my post !

Here are some pictures of the actual PCB.


This is completely identical for the moment and the pcb is Blue in order to avoid confusing in term of support or bugs.. and also not to add overhead to othermod. But everything is compatible in term of image, drivers etc..
I want to put a female smt GPIO header for next iteration in order to avoid solder in the pcb. Rather solder the pin header on the Pi Zero.
My ultimate Goal will be to integrate a Compute Module 3 and use the Screen in 24 Bit DPI mode instead of 565 DPI mode.

I have decided also to name this project PiSP for "PI Systeme Portable" in French, because my aim is not only to play emulation, but also Pico8 or Lua / Love2d games, Python etc, so it can be a good system for developpers who want to share their code to others :D

Look at what this japanese guy have done in Love2d with the raspberry Pi Zero...


P.S : I May open a new post elsewhere in the forum
