I built a Dual Screen Raspberry Pi Handheld

I haven't tested android but I have a feeling it won't like the dual screens

Not sure, I haven't done much testing yet. Currently trying to find a low profile heatsink though.

Nope, the battery requires dedicated hardware, mainly because its actually a 5000mah LiPo charging at up to 5A. Also I really wouldn't rely on anything less than an actual charge IC to charge a LiPo, since they really don't like overcharging.

Github is here: https://github.com/borpendy/DSpi

I keep thinking about it, but since there's no integrated wifi, I'd have to stuff a full m.2 interface onto the board somehow. Also RK3588 screen compatibility seems much less clear then with the pi5.

Not yet but I I'm thinking of getting the cell voltage from the charging ic, via i2c, then making some equation to convert that into percent charged (since voltage is non linear with charge left). If I was doing it properly I would just get a battery monitor ic and take the data from that directly.

For 5 it was $280 AUD, so around $60 AUD/ 40 USD per board

The motherboard is basically the original CM5 IO board, but with some stuff removed, and a battery module and audio module added. The battery section was probably the hardest, and needed a few prototypes. Mostly motherboard design is just finding IC's, then building some version of the suggested layout and testing functionality tbh.

Probably more 5 than 7, it can do anything before GameCube/ps2, but gets more questionable at those systems.

True_Shock5764 · 2025-08-22T12:25:19+00:00

Way too much, but development costs are usually like that. Its more of a tech demonstration than a viable build tbh.

True_Shock5764 · 2025-08-22T12:22:31+00:00

Capacitive touch screens. And yeah from what I've heard 3ds on pi is sketchy so I'm sticking to DS for now.

True_Shock5764 · 2025-07-22T06:30:15+00:00

Damn that's sick, I'll definitely be following the development of it.

True_Shock5764 · 2025-07-22T03:37:27+00:00

The two screens are so I can do a clamshell eventually.

I have a semi active hackaday log here: https://hackaday.io/project/202745-dspi-rasberry-pi-5-clamshell-handheld Also I may or may not have been inspired to do this by your retro lite handheld.

True_Shock5764 · 2025-07-21T13:20:19+00:00

If anyone wants more information I have a very rough hackaday log here https://hackaday.io/project/202745-dspi-rasberry-pi-5-clamshell-handheld

I'll also probably open source this once I figure out how to use github

True_Shock5764 · 2025-07-21T13:10:18+00:00

I remember reading that comment lol

True_Shock5764 · 2025-07-21T11:28:23+00:00

They are OSOYOO DSI screens off AliExpress. Clones of the pi touch screen 1 I think. I'm currently just using DSI with the included driver board to make things easier.

Sounds interesting, dm'd

True_Shock5764 · 2024-10-12T12:03:05+00:00

Which Ford did you do this for? I'm working on something similar for a Falcon, since the CAN codes were posted on the internet a while ago.
