ESP32 Web Kit
Documentation
The documentation for the ESP32 Web Kit can be found at: https://heltec.org/project/wifi-kit-32/
One of the most important documents is the Pinout Diagram: https://resource.heltec.cn/download/WiFi_Kit_32/WIFI_Kit_32_pinoutDiagram_V2.pdf
For advanced users there is also a schematic (should not be required in the basic class): https://resource.heltec.cn/download/WiFi_Kit_32/WIFI_Kit_32_Schematic_diagram_V2.pdf
Errors and Problems
It seems there is a false marking on the additional labels that come in the box. On the left side the additional label says 5V - but the associated pin is actually 3.3V
