 First of all, the ESP-12e module has 22 pins available. Let’s read the names of all.

Name of PINs with their Purpose or description.

  1. RST: It is a reset pin. Used to rest all the data incoming or outging, and restart from the code block 1.
  2. ADC: It is used for analog to digital converter, generaly used to convert your voice to 0-1 format.
  3. EN: It is used to enable the module. Max of the cases it is the VCC( + ive terminal of the supply)
  4. GPIO0, 2 ,4 , 5, 9 ,10, 12, 13, 14, 15, 16: It’s a General Purpose Input-Output Pins. You can send your data here
  5. VDD: It is a +3.3volt power input pin
  6. CS0: It’s a chip selection pin
  7. MISO: It is for SPI interface
  8. MOSI: It’s also for SPI interface
  9. SILK: It is an SPI interface clock pin.
  10. GND: It’s for ground(- ive)
  11. RXD0: It’s for receiving the data
  12. TXD0: It’s for transferring data.

There is 11 input/output pin, which is used to give the input and output. RST is also a critical pin. You can rest your board of nodemcu using RST. Now we have studied both modules. Let’s check the error which comes from the board of nodemcu.
