AMAZING WORK!

[@SalvatoreRaccardi]

Thank you for supporting the project!

[@tablatronix]

lovely board

[@yazanajaj3389]

Love your job so keep going🤗

[@SalvatoreRaccardi]

Thanks, I will do it🔥!

[@sandeepsharma9833]

I love this

[@hfe1833]

Very good looks promising

[@SalvatoreRaccardi]

Thanks! In a few days I will show the new version that will be sold.

[@PiccoloFrank997]

Good job!

[@SalvatoreRaccardi]

Thank you!

[@lkqbgvliqewpgviqe]

Hey, man! Great and inspiring work! Do you do this for a living?

[@SalvatoreRaccardi]

Thanks! No for now it's not my job, it would be nice if it became. I currently study software engineering.

[@ayanvaidya2727]

looks really good
is there some way to connect more peripherals ?

[@SalvatoreRaccardi]

yes, I have developed modules that allow you to do this.

[@ayanvaidya2727]

@@SalvatoreRaccardi i will be waiting for that

[@lacipaci4]

Hi!
Very nice work!
What's the range of the Wi-Fi/Bluetooth? Is this small ceramic antenna has good range?

[@SalvatoreRaccardi]

The range is a few meters with the presence of obstacles (for example a concrete wall), the antenna that I used in this prototype will be replaced in the future with an antenna that is always ceramic but more performing.

[@lacipaci4]

@@SalvatoreRaccardi
Thanks
How did you design the antenna for the esp32? Was it just trial and error or you have some solid knowledge in antenna design?
It's not related to this project but I want to design my own pcb with esp Pico d4 but I'm pretty lost with the antenna.

[@SalvatoreRaccardi]

@@lacipaci4 I have read some docs on the internet and have done some tests. Then I also analyzed some PCBs that used antennas of this type. I still have a lot to learn about RF circuits.

[@GuoTony]

GREAT WORK!
Can ESP32-PICO-D4 directly use Arduino IDE for serial programming?

[@SalvatoreRaccardi]

Yes sure you can use ARDUINO IDE with ESP32 Core👍

[@MauricioSierra]

Do they sold you the components?

[@SalvatoreRaccardi]

I don't understand the question

[@lamngoc9896]

can you share pcb v1.0? 😅

[@SalvatoreRaccardi]

You can find it on github: github.com/salvatoreraccardi/OBJEX_LINK/tree/main/boards/OBJEX_LINK-Rev1.0

[@vvnnable]

where is antena patch?

[@SalvatoreRaccardi]

there is a ceramic antenna with the pi network
