Re: Pi in a PSP

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 ship...

Re: [For Sale] mintyPi BatteryMonitor PCB Preorder

Hey Helder and HoolyHoo, Someone just emailed me saying you had the battery overlay so I came to check it out. I see you're using the same IC and original code as I am. I've been tinkering with this chip and code for a few months and have something you guys might be interested in. https://github.com...

Re: [Update #7] Inches' CeMu+(S)AIO board (Compute Module 3 build)

Is this schematic up to date with what you've been using? https://othermod.com/raspberry-pi-advanced-soft-onoff-circuit/ It is. I use it to switch the EN pin on the boost converter on and off instead of switching 5v on and off though. That way no power is being pulled from the battery when the syst...

Re: [Update #7] Inches' CeMu+(S)AIO board (Compute Module 3 build)

Looking good. Any plans to use switching regulators instead of linear ones? Yes, the linear ones are for this first build. I would need too many more iterations for this one to fit my schedule goals for releasing it if I were to implement that. I need to pin down power solutions and safe shutdown f...

Re: Pi in a PSP

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...

Re: Pi in a PSP

@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 convin...

Re: Pi in a PSP

He seemed to be talking about tapping into the HDMI signal in some way. I can't be sure though. I would love to integrate something like this onto the board, and then use an FPC cable instead of an HDMI cable to save space. http://www.ebay.com/itm/4-3inch-HDMI-LCD-480-272-Resistive-Touch-Screen-Disp...

Re: Pi in a PSP

My screen finally arrived and I got it working last night. Next step would be wiring in the psp controls. I'll have a try at the PSPi v2 approach and see how that goes. The all-in-one board looks very promising though. It'll definitely be a cleaner solution ;-). In a future revision it would be coo...

Re: Pi in a PSP

No problems but when you hit the Ratnest button it will tell you in the lower left hand corner if anything is unwired or has errors. @Helder I didn't even notice that. It was right in my face too. :lol: I've got three of the boards on order, so if you're looking to do this project I'm happy to send...
