Review on 🌟 Enhance Your Arduino Experience with ELEGOO UNO R3 2.8 Inches TFT Touch Screen: SD Card Socket Included! by Yung Kaelin

I just got this display so haven't worked with it much yet. All examples compiled well. Contrary to one of the reviewers who commented on the libraries provided on the mini-CD, I just grabbed the latest AdaFruit libraries straight from GitHub (and found a compilation error in a module) and had no problems. I'm using this with an Arduino UNO so it fits perfectly and doesn't cause any compatibility issues with the uSD card. I'm not sure what I'm going to use it for, but for the price, it's a really sharp, compact graphics display. Love the fact that they included a minidisk with examples and a stylus for touch mode. Update: I really like this display after playing with it for a while. The only problem I have is that it fully accesses all pins on the Arduino board. I'll have to revisit this to see which pins the display is actually using and which are still available for additional I/O. In the meantime I've installed it on a couple of contact strips which give me access to all contacts while still having the display properly seated and using all the contacts I need. Right now this is great for prototyping projects. I've just ordered two more of these displays because it's so much for the performance they offer. Another update: I just checked all the pins marked on the board and the code for the helper libraries. The display appears to be using all pins except A5 and serial I/O pins 0 and 1. This pretty much rules out using other peripherals with Wire, SPI, or I2C. The SD card uses digital pins 10 through 13, so if you don't need the SD card you can cut these pins off (and not include the SD library in your project). Otherwise the options are limited. And another update: this thing also captures interrupts. It works much better on a Mega 2650 board with extra I/O pins, but any libraries that use interrupts are inefficient. I downgraded my rating to 3 stars as this is nothing more than a novelty without sufficient technical documentation from Elegoo.
