/* Using the OLED */
== Module with TTGO written on it, featuring 18650 battery holder ==
This is also a clone and very likely not from TTGO. It is equipped with an OLED display and a 18650 battery holder including some kind of charging circuit. The antenna placing of the module is not very wise - the Wifi performance is reduced somewhat compared to modules with a better placing.
== Arduino ==
Select "WEMOS LOLIN32" to work with the modules.
== Using the OLED ==
For both modules it seems that the OLED display is accessible by GPIO5 is SDA, Pin GPIO4 is SCL using this line with the [https://github.com/squix78/esp8266-oled-ssd1306 squix78 ssd1306.h] Library: <pre>SSD1306 display (0x3c, 5, 4);</pre>
