These pins can be easily integrated into capacitive pads, and replace mechanical buttons. - Supports up to 8 MB off-Chip SPI SRAM. The block base is actually the GND contact, reason for which you will find that most datasheets claim 49 pins. On the ESP32 based NodeMCU almost all pins can be used as either INPUT_PULLUP or INPUT_PULLDOWN, but there are a few exceptions:  Steer clear of pins 6-11 because they will prevent the board from booting if used as an input, Pin 34-39 don’t work with an input pullup and pins 0-3 don’t work with an input pulldown, there are plenty of other pins available, so just skip those. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Given that, this post shows how to use ESP32 development board to read temperature and humidity from a DHT22 sensor. Input/Output Pins (GPIO): You can use the 32 GPIO pins to communicate with the LEDs, switches, and other input / output devices. There’s also a source of official information in the ESP32 forum, but there’s not much news there just yet. ESP-WROOM-32: This is the heart of the ESP32 module.
