The boards are back in stock. I adjusted prices to cover the new tariffs. My gut feeling is that these tariffs will remain for a while. I am no longer doing free shipping on the PSPi boards. Shipping is a set $9.95 regardless of where you are.

Sooo. do I put my boards back in stock at an increased price, or do I wait to see how the tariff stuff plays out?.

The new Raspberry Pi DPI Topper board is working well. The (hopefully) production version is here and passing all tests. This new board has: .24-bit video using the same 40pin display connector pinout as the old topper boards.Adjustable brightness (8 levels) using the onboard

So it seems it will take a bit of time for the CM5 color issue to get worked out on the Raspberry Pi GitHub. They said they plan to fix it early in the year, and then it will take a long while for those changes to work their way downstream to other operating systems. Sooo, im.

I made progress on the new Raspberry Pi DPI Topper board (for Pi 0, 3, 4, and 5). Looking for some feedback. The goal here is to make a single board that can be used for lots of projects. It has most of the PSPi features, except for battery charging and power handling. This

The temporary fix was to change the color shift here to (9, 29, 19). I've asked Raspberry Pi to implement a proper color change in the overlay. If you are able, give my bug report a thumbs up so they know to put time into fixing it.

I'm making progress with the CM5 on my board. I don't think a new carrier board is required. The color order was corrected by changing some code in the video driver and recompiling linux. This is just a hack until Raspberry Pi implements a proper fix in their code. I've

I have the Raspberry Pi Compute Module 5 running on the PSPi 6, using the carrier thats made for the CM4. So far, it seems to be working. There are some coding things that keep the battery indicator from working and that cause the LCD colors to be swapped, but other than that

I'll update the discord channel as I make progress. You can download the model there if you want to tinker with it.

The PSPi 6 board allows for a second joystick and two extra buttons to be added, but its tough to actually do it with the stock shell. I spent some time 3D modeling the front shell using one of the high quality scans. This is pretty basic still, but the overall shape and

I managed to get one. If anyone sees a CM5 Lite in the US, please let me know.

The main gamepad driver is now reworked too. Like the atmega code, its more readable. There are layers of complexity that you can dig into, but the general flow is simple. It runs more efficiently, and I added some features:.The driver now emulates a PS3 gamepad, so detection.

I reworked the atmega microcontroller code that runs on the PSPi 6. No major changes, but its sooo much easier to read. The atmega sketch is now just a small loop with the basic functions, and those functions get more in-depth the deeper you go. I also.

I wonder whether this new Pi5 chip with the D0 stepping will end up in the Compute Module 5.

My DPI Topper board has been out of stock for a while, but I'm finally working on getting a batch of them produced. I decided to make some improvements, and want your thoughts. I'll probably make a few different versions. The one shown here is what I am calling "24-bit
