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 Stacy Sturm

Unlike some other ESP32 boards with screens that are flush to the board, this board has the screen mounted on a translucent standoff that extends 0.2" above the board . This is very handy for packing into a larger project - the board can be mounted inside the project case, with the screen mounted flush with the outside of the case. Boards with screen mounted flush to the board are about the same height as the ESP32 itself. and is not suitable for housing for a polished end product. Note that you will need to solder the pins to themselves. That's my opinion not bad as you can mount them backwards or use a 90 degree pin header depending on your needs. The sample code on the board scans for open WiFi hotspots. It finds mine and my neighbors with good signal strength on the back of the board. The connector type is Micro JST, widely used with small RC airplanes and helicopters. A quick search for Revain will give you several battery options. Since the connector is flush with the board, you'll likely need a pigtail to connect it.
