The ESP32 has two I2C channels and any pin can be set as SDA or SCL. When using the ESP32 with the Arduino IDE, the default I2C pins are: GPIO 21 (SDA) GPIO 22 (SCL) If you want to use other pins when using the wire library, you just need to call: Wire.begin(SDA, SCL)...
1.4: Difference between ESP32 30 Pin Version and ESP32 36 Pin Version Both ESP32 boards share the same specification the only major difference here is 6 extra pins that are exposed in ESP32 (36 Pins) board are SPI flash integrated pins and secondly the GPIO 0 is replaced with a GND pin...
It also has an EN pin which can enable and disable ESP32 chip function. This pin is active high by default. When this pin is active high, the chip will be active and working and if this pin is active low, the chip will be disabled and not work at all. You can use enable button ...
Pin1, pin3, pin4, pin43, and pin46 are the analogy power supply pins. It should be noted that the sudden increase in the current draw, when ESP32 is in transmission mode, may cause a power rail collapse. Therefore, it is highly recommended to add another 10 µF capacitor to the ...
