    • Great little screen for fun projects
Color: 4.0 Inch ST7796 TN Touch
I bought this ESP32 display to experiment with making my own little gadgets, and it’s been a blast. Everything you need is right on the board- a fast ESP32 chip, a bright 4-inch screen, and tons of ports for adding extras. It even has Wi-Fi and Bluetooth built in, so you can connect it to other devices or the internet. The screen is colorful and clear, and the touch works well with the included stylus (it’s a “resistive” touch screen, so it works better with a bit of pressure instead of just a fingertip). Getting started was simple: I plugged it into my computer with the included USB-C cable, installed the driver and programming software, and I was ready to go. The online tutorials and example projects made it easy to load my first app and see the screen come to life. If you’re into DIY electronics, making smart home gadgets, or just want to learn how to create your own touch-screen projects, this is a great choice. It’s easy to use, fun to experiment with, and packed with possibilities. ... show more

    • False advertising
Color: 3.5 Inch ST7796 TN Touch
Not actually a miner, comes with no set up or firmware. They expect you to download and pay for your own firmware and go into the device code to set up. False advertised, the picture does not match the device. The interface the image shows has to be manually downloaded through a series of different downloads and data files. Comes with no case. The posted tutorials are not very helpful. ... show more

    • Missing 2-pin cables
Color: 4.0 Inch ST7796 TN Touch
Really nice board. Im greatly enjoying using it and the tutorials are great! However, I dont understand why the board has 3 2-pin jst connections, but the product only comes with 1 2-pin cable. This is super inconvenient as now I need to get additional jst connectors for my project. Outside of that, works great. If you need all of the IO however, make sure you get some 1.25mm jst connectors / cables. ... show more

    • Very happy
Color: 4.0 Inch ST7796 TN Touch
I absolutely love this thing. The 4.0 screen is decent and installation isn’t hard if you just take your time. I’ll be buying more. Just talked my buddy into getting some. I’m very pleased. I’d buy again and shipping was as advertised.

    • title is misleading, this is just the dev board no miner installed
Color: 2.8 Inch ST7789 TN Touch
it works, you need to flash it yourself. If you only read the title you will be mislead, this is just the board the miner is not installed.

    • Not worth your time or money
Color: 2.8 Inch ST7789 TN Touch
Not at all as it was portrayed. The “detailed” instructions aren’t helpful at all. There is no case with it, just a board. Apparently we are expected to seek out and download extra firmware which we only found out by reading comments from other frustrated customers. Very disappointed as we thought this would be a fun gift… so we bought three of them. Didn’t think anything of it until Xmas when the gifts are opened, projects started and realizations set in. Don’t waste your money or time. ... show more
