Bicool 2X 40PIN GPIO Header Dual 40Pin Adapter for Raspberry Pi 400 Keyboard Computer,Header Expansion,Color-Coded Header,Easy Expansion

Since these extend male connections I don't know how to use this without a T-cobbler. So I mostly just alleviate the awkward 90 degree bend of the T-Cobbler.

I would really like to see a positive marking for pin 1 on both connectors for this product, it would be great as a breakout for Pi bench work. Minus one star for not properly marking orientation, I shouldn't need a meter to tell which side is pin 1.

Won't power on anymore. Power light flashes, then shuts off and does nothing.

The Pi 400 is such a great little computer, it reminds me of my old Commodore 64 and Amiga 500. I purchased this combo from another company since Amazon didn't carry the Pi 400 at the time.I've had a few barebones Pis over the years. I use a Pi 3 for my Ubiquiti Unifi network controller software. But this little computer is a game-changer if you want simplicity. It is much easier to have everything built into a keyboard like this so you don't need a Pi with an external keyboard attached to it. Just add an inexpensive 15" portable monitor (the thickness of a tablet) for about $125-$150 and you have a sweet little computer that is great for newbies and experts alike. And since you can change the SD card in the back, you can run any kind of operating system, or multiple, and swap them out at any time. You can have a retro gaming computer using RetroPie, and then have a productivity/development one with your favorite Pi 400-compatible Linux OS. The possibilities are endless.The system is pretty fast... noticeably faster than my Pi 3. The included Raspberry Pi OS (formerly Raspberian) is easy to use. The only downside to this package is that the included power supply doesn't have a switch on it, so to turn the Pi back on after shutting it off, you have to unplug it and then plug it back in. It feels a little uncool.Highly recommended system for so many different kinds of people. Five stars all the way.
