Which ESP32 Board Pinouts will be available in future market ,38 pinout or 30 pinout? As we are designing PCBS due to non avalibality of 38 pin ESP32 we are finding difficult to match 30 pin ESP32 on board. So please do tell if 38 pin esp32 will be hereafter not be availabe in ...
As mentioned earlier, the chip used with this board has 48 GPIO pins, but all pins are not accessible through the pinout of development boards. This ESP32 devkit has 36 GPIO pins and 18 on each side of the board as shown in the picture above. It has 34 GPIO pins and each pin has ...

Pinout ESP32-C3 Super Mini.png The display has the following SPI Pins: BLK = Backlight DC = Data/Command RES = Reset SDA = Serial Data or SPI MOSI SCL = Serial Clock or SPI SCK VCC = VCC (3.3 Volt) GND = Ground I am connecting the ESP32-C3 Super Mini with the display using ...
The I2C pins stated above are set in default. If we want to change the GPIO pins we have to set them in code. The diagram below shows the pinout for the ESP32. ESP32 I2C Pins Note: If we use other GPIO pins of ESP32 for I2C communication, we can define other pins inside our Ar...
