Review on 📡 HiLetgo ESP32 OLED WiFi Kit - Internet Development Board for Arduino ESP8266 NodeMCU with 0.96 Inch Blue OLED Display, WiFi, Bluetooth, and CP2012 by Danielle Ward

In my previous review I showed you an ESP32 connected to an external OLED. This paragraph takes it to another level. This module has an OLED on the board. The default program is a WiFi scanner. Give it power, wait 5 seconds and see what networks this module finds. Great for stealth driving. You can also use it as a signal strength scanner at home or in the office. You can also flash it with another sketch and do the same as with ESP32 and OLED (weather station, graphics generator, etc.). About the item: This item was shipped quickly. It is in excellent condition. Caveat: you need to remove the OLED to solder the pins. Please use the smallest dot you can find. Your 20th century soldering iron for 18 gauge wire won't cut here. I made it, but I was lucky.
