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
ESP32 DevKitC v4 high resolution pinout and specs
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.
Bye Renzo
“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.
Bye Renzo
Hello, how come the devkit-v1 board has 30 pins, the pinout of the board reflects this too, but the schematic presents 2 20 pin connectors with 19 active pins on each side??
Hi,
I think you are right, I’m going to fix.
Bye Renzo
