I cut the stripe and I checked all the connections. Here are some pictures to show how things are connected, in and out, etc.

Until now I only tested the display without the touch functionality and that works fine. I used the ESP32 SPI Master Example for testing.

Q: Where is the CS pin? How can this be used on a SPI bus without CS pin?

Asked by BucksBiker on 2019-07-22 09:31:32

Edgar I also look for the CS pin. The answer "check the instructions please" seems to be useless because I don't see any instructions. There was also no documentation (not even a small paper) included.

The most powerful Arduino on a small board. I like this! I was not sure how to program it. Finally I figured it out. Here is a description: https://arduino.stackexchange.com/questions/61531/how-to-program-the-robotdyn-mega-2560-pro-mini/61532 I added lots of colored pins to make it easy to play around with this. I bought this pins extra, they are not part of this product.

I bough these to convert 12V from a motorcycle to 5V to supply LEDs. It does the job. And the quality looks good. Attached is a picture with the label. Here are technical details and a data sheet: http://www.wengaoelec.com/12V-24v-to-5V

It's obvious by looking at the pictures. But I have to admit I bought that box to protect an Arduino against dust and dirt. But that obviously did not work if all contacts are exposed to the outside. I don't blame the case for this but people who buy it should be aware of this.

Good product, almost like described. Here are my corrections: power usage: one color 100%: 11.3W two colors 100%: 22.6W three colors (white) 100%: 33.9W (that is the max it every used) the stripes are 10mm wide What I did not expect: The LEDs get hot. It's still possible to touch them but only just about.

I like that this drive has a normal and a secret partition. If someone unauthorized puts this in a computer the normal partition will come up. And I guess that will satisfy 90% of the users that there is nothing secret on that drive. But if the finger is put on the fingerprint sensor then the secret partition appears. The owner can use this. Other unauthorized users won't even know it's there.

This is one of those small devices which is not really necessary but nice to have. It does what it should do and it's cheap.

I use this since about two months with my Surface 1 and it works fine. The cable is a little stiff but still ok.

I purchased this without having and Android phone and I was not even able to set the time correct. This "watch" needs an Android device for the setup. Now I have an Android phone, I could pair it and it works.

These LED strips are ok but not what I had in mind when I ordered them. They have 12V, R, G, B connectors. The whole stripe will always have the same color. What I wanted to order were individually addressable LEDs which are also available in strips. But they are more expensive. Obviously Banggood is not responsible for my misunderstanding. But I am sure others will possibly make the same mistake. So check in detail what you want before you order them.
