Recently I bought a ESP32S Dev Kit C V4 NodeMCU WLAN Development Board. I got it from azdelivery.de in Germany. Now I am interested in the schematic for this board to learn more about it. Not Google, nor the support team at azdelivery.de could help me, but since the board is a Chinese mass product, I hope to find an answer here, where I could get the schematic. Thank you!
