Review on High-Definition Touchscreen Raspberry ROADOM: Responsive & Compatible 10.1" Display with Built-In Speakers by Josh Bartlett

Advantages: The circuit board is very high quality, many cables are included. I was afraid I would have to buy cables but I wasn't sure so I waited for them to arrive. I was happy to see all the things that come with it. It also comes in beautiful packaging that has the same level of quality as Apple products. Cons: only 2 things. First, the flat ribbon micro HDMI video connector is very difficult to use. On some connectors, use your thumbnail to pry out the locking mechanism. It didn't work and I picked the lock. I finally have him back, but I'm not sure if he's that strong now. Users need to turn it upside down, insert the tape, and then press the latch. None of this is mentioned in the quick start guide. It took me almost 2 hours to fix the connector and connect the ribbon cable. Second, the included USB charger (which is used to power the screen and RPi) does not provide enough power. With the added screen, I keep getting low voltage detection errors. Sometimes the green text flickers, causing green "OK" messages to flash when Debian boots. When I turn off the device, it's usually gone. It hit or miss as I often saw green text flickering. I have a USB-C based wall outlet that I use for the RPi but there is no way to connect it to this shield. Because the RPi4 is powered this way, this LCD panel had to use it as the power connector instead of a flat micro USB (Android type). Things to improve: A mini HDMI ribbon cable is included (the one mentioned above which is difficult to fit into the ribbon cable socket) to eliminate the need for a large bracket/cable from the RPi to the display. However, the orientation is wrong, so twisting/tilting/twisting the cable 90 degrees is backwards, causing it to stick out from the bottom. If the orientation of the micro-HDMI was changed correctly, I could probably use the sticky part of the cable that came with it to place it on the screen. You had a 50/50 chance of getting it right and it's wrong. More power is required from the USB charger. I don't get any low voltage warnings when powering the RPi4 via USB-C and the display is via micro USB. But the USB-C cable coming out of the bottom of the RPi4 prevents the screen from standing up. I've tried powering the RPi with just USB-C and using the included 3-pin power cable to power the display. There was huge flickering and I was afraid of burning something, so I quickly unplugged the USB-C power supply to avoid damage. It would be nice to have this reverse power method available to power the display, but it's possible that the RPi is current limiting so there's nothing that can be done.
