Review on 📡 HiLetgo ESP-WROOM-32 ESP32 ESP-32S Development Board: Dual-Mode WiFi + Bluetooth Microcontroller with Integrated Antenna RF AMP Filter for Arduino IDE by Trey Samuels

**Update** After about 30 days of operation, this ESP32's wifi module died - it outputs random data, then keeps crashing every access WiFi. I have two other esp32s purchased at the same time from another vendor that run the same code with no problems. I am still using the paper receipt they sent as it is identical to the other unit so the 1 star rating is saved. -------------- I bought several ESP8266 and ESP32 from different vendors to test several options. I've seen almost every seller and product have random reviews for items that haven't shipped, but I haven't had a DOA on any order. I prepared for this product by reviewing the documentation and reading other people's questions/answers, as well as reading sample programs written by others. My HiLetgo ESP32 successfully ran the web server test program after adding the board libraries to the Arduino software very easily. The process is similar for each board except for the basic Arduino options. No drivers needed to be installed for Windows 10. HiLetgo was the only vendor that provided ANY written documentation - something most development boards and electronic components these days don't seem to provide. I appreciated the schematic and pinout - nice to have handy without having to check the computer screen.
