How Many Gpio Pins On Esp32
GPIO pins 21 and 22 are the default if new pins are not declared. Telegram is all about freedom and open-sources it announced the new Telegram bot API in 2015 which allowed third parties to create telegram bots for ESP32 that utilize the messaging application as their main communication interface.

How many gpio pins on esp32. The PSRAM pins should be 16 and 17 I found you already used it. You can always pull-up the LCD RD pin and free up GPIO 32 for LCD DC pin. We have several guides about MQTT with the ESP32.
They dont have enough GPIO pins. And also you can always pull-down the LCD CS pin to free up GPIO 5. Youll note the use of pullup resistors for the I2C data and clock lines.
So now Im looking at the ESP32. Telegram Bot with ESP32 Control GPIO Pins through Telegram Chat. Oh yes 12 13 and 14 is SD pins.
Then you can use GPIO 27 for LCD D5. As we are using 33-volt logic you should use values in the 24k to 33k neighborhood. Do you have the same guides for getting the ESP32 programmed for MQTT.
Actually you can use any two pins on the ESP32 for your I2C connections and define them in software.
