the ESP32 has 48 GPIO pins in total, only 25 of them are broken out to the pin headers on both sides of the development board. These pins can be assigned a variety of peripheral duties.
Description
| Memory | 256 MB |
| Country of Origin | Made in India |
Although the ESP32 has 48 GPIO pins in total, only 25 of them are broken out to the pin headers on both sides of the development board. These pins can be assigned a variety of peripheral duties, including:
| 15 ADC channels | 15 channels of 12-bit SAR ADC with selectable ranges of 0-1V, 0-1.4V, 0-2V, or 0-4V |
| 2 UART interfaces | 2 UART interfaces with flow control and IrDA support |
| 25 PWM outputs | 25 PWM pins to control things like motor speed or LED brightness |
| 2 DAC channels | Two 8-bit DACs to generate true analog voltages |
| SPI, I2C and I2S interface | Three SPI and one I2C interfaces for connecting various sensors and peripherals, as well as two I2S interfaces for adding sound to your project |
| 9 Touch Pads | 9 GPIOs with capacitive touch sensing |
Thanks to the ESP32’s pin multiplexing feature, which allows multiple peripherals to share a single GPIO pin. For example, a single GPIO pin can act as an ADC input, DAC output, or touch pad.
