- GPIO Pins: The board provides numerous General Purpose Input/Output (GPIO) pins which can be used for various digital input/output functionalities. These pins also support functionalities like PWM, I2C, SPI, and more.
- Analog Inputs: Several pins on the ESP32 DevKit V1 are capable of reading analog signals, making them suitable for interfacing with analog sensors.
- 3.3V and GND Pins: These are used to power external components or sensors.
- 5V and GND: The board can also provide a 5V output, which is useful for powering external modules that require more power.
- VIN: This is the input voltage pin, which can be used to power the board when not using the USB connection.
- EN: This is the enable pin. It’s used to reset the microcontroller.
- TX/RX: These pins are used for serial communication.
- SPI Interface: The board has pins for SPI communication, enabling fast data transfer with peripherals like displays or flash memory.
- I2C Interface: The ESP32 DevKit V1 supports I2C communication, which is widely used for interfacing with sensors and other peripherals.
- Touch Sensor Pins: Some GPIOs can be used as capacitive touch inputs, offering an interface for touch-based input devices.
- VP/VN: These are the pins for the internal hall effect sensor.
- USB-to-UART Bridge: This feature is crucial for programming the ESP32 using a USB cable and also for serial communication with a computer or other USB host devices.
This board’s flexibility with various protocols and interfaces makes it ideal for a wide range of IoT and embedded system applications.

Hi there, Is that possible that we can also get the board dimensions of this part? we are trying to create a footprint and we need that information.
Hi Ron,
the size is 28,2mm x 51,800mm, but here you can find the svg file in real size, with all holes and pins.
I think It’s good for you.
Tell me if you need more informations.
Bye Renzo
well i really need the dimensions of this board for footprint, like the gap between pins and so on . I hope you can help me out my man..
Hi Aidil,
the svg in the comment is in realsize, so you can get all the dimension you want.
Bye Renzo
bullshit mine has 36 pins. thats 18 on each side for the FUCK IT DEVIT
Hi, hehehehe check this

Bye Renzo
hello, i need to fine the exact measures of the module of the esp32 devkit v1 (30 pins) like the distance between pin-pin
Hi joaquin,
you can find an image of It in real size.
Bye Renzo
is it possible to add an antenna to the board?
Hi Davey,
you can add It, but It isn’t a simple operation:
but I think It’s better if you chose a micro that use 32U version of esp32 (with embedded antenna connector).
Bye Renzo
sir how many esp32 boards types are avalabile l
Hi,
exist a lot of prototype board, some of the main manufacturer are WeMos, Lilygo, Waveshare.

“5V and GND: The board can also provide a 5V output, which is useful for powering external modules that require more power.”
That’s not true. There is not pin to handle 5V output.
Hi M,
The datasheet explains that EXT_5V is used for USB and VIN, so you can use It, and I used it for my project with success.
Bye Renzo
Hello, continuing M’s topic – I am powering the board via the USB so at my Vin I am having 5V. I am using those 5V to power the circuit I am using but is there a possibility to toggle between ON and OFF this Vin output?
Hi The,
no It’s directly connected to the USB. To control the power you can use a transistor like the 2n2222.
