I am using EasyEDA to create a schematic and PCB but I am not able to find a community generated symbol for my Arduino Uno R4 Wifi. How do I go about adding the schematic and 3D file to EasyEDA?
I have no idea and no experience with EasyEDA or the R4. Can't you simply use a Uno R3 symbol as the pin out / pin functionality should be exactly the same.
Note
If you don't come right, EasyEDA has its own forum: Forum - EasyEDA Open Source Hardware Platform Forum at oshwlab.
But I am creating a shield, so the exact pcb measurements are needed
Do R3 Shield templates work with R4 Wifi in EasyEDA?
The Uno R4 WiFi has the same pinout as the Uno R3 and it has the same physical layout so you should be OK
A prototype shield that I have that fits the Uno and Leonardo certainly fit on the Uno R4 WiFi, but I have not had a reason to use one yet
Just be aware that pins 0 and 1 on the Uno R4 boards belong to the Serial1 interface rather than Serial

Points to pay attention to (look at the schematics)
- I2C
- SPI
- Serial (see earlier reply by @UKHeliBob)
And maybe mounting holes but they should be the same.
Are there any licensing restrictions or copy write on using the symbol in your own products … probably ?
“ It is a common misunderstanding that since Arduino technology is open source, the name and logo can also be used freely, but that is not the case. Anyone is allowed to copy and to further develop an Arduino open source hardware design into their own product as long as they use their own brand name and logo for this product.”
I am making a shield, not a full arduino.
I am using an I2C LCD.
When I saw the pinouts, the only difference I saw was that R3 had only one spot for sda/scl.
Do you have any places that i can find r4 wifi sheild template for easyeda?
I guess you did not look at the schematic. There are two places (A4/A5 and the dedicated SDA/SCL pins).
The only extra pins on the Uno R4 WiFi that aren't on a Uno R3, that could possibly be used by a shield are the pins arrowed below:
These pins are used to turn on/off the 5V buck converter, and to attach a back up battery for the RTC.
Unless you have a specific requirement to use those pins there is no need to make any connections to them.
If you do decide to use them they are on a 0.1" pitch, in line with the 8 + 6 pin power/analogue connector. There is a 0.2" spacing from the end pin of the 8 pins.
Because the Uno has pins, the mating female connector would need to be mounted on the underside of the shield.
This would prevent the shield from fitting on an Uno R3, as there is a diode fitted in that position.
Edit:
That might be untrue, since the height of the diode is no higher than the plastic part of the 3 pin connector on the Uno R4 WiFi.
That includes any hardware , so you can’t put on a shield either that you intend to sell
Ok, thanks for the heads up, but I am trying to make a school project and will not be selling the shield.
