Review on KeeYees Internet Development Display Bluetooth by Jaime Bustamante

The product I received had a curved OLED screen but for a breadboard this would be acceptable. There was no pin sticker in the product description. The default program loaded on the ESP32 didn't work and I thought the product was buggy. I did not attempt to change the program in case I had to work with support to fix the problem and justify a return versus mine or someone else's program. The program should find Wi-Fi networks and display their names. The default program reported finding "-2 networks" and didn't list any names. I requested a replacement from Revain and it also had no pin stickers and the standard program didn't run either, but at least the OLED was basic. I downloaded someone else's wifi scanning program and it worked. Stickers would be nice, but don't have to. So -2 stars for out-of-the-box experience and +1 for easy Revain replacement. The white Apple style USB cable looks like a fake Apple but works great and has good flexibility.
