ESP32-NodeMCU pinout not found
Posted: Tue May 12, 2020 1:35 pm
I have bought an ESP32-NodeMCU from a store called "SZ Aitexm Store". The store has named it as "NodeMCU", I have searched a lot for a pinout for the NodeMCU, but found nothing. This is the link for the NodeMCU, it is the fourth choice from the left: https://www.aliexpress.com/item/32656775273.html . This is the link for the store that I bought from: https://www.aliexpress.com/store/1095279 .
I have found nothing that refers to the exact same PCB that I have. However, I have been searching for its pinout because I have found some pins that are confusing, for example, the GND pin next to the 5V pin gives 2.2 V nearly, sometimes it differs. And the SD0, SD1, SD2 and SD3, I don't know the use of these 4 pins, along with the "CLK" pin, near the "SD0" pin. I have even found SN and SP pins near to each other, what are these? could someone please explain the pins that I have just mentioned, or at least try to give me a pinout for that PCB. I just feel like the PCB that I have is wrongly designed.
