Schematic symbols and PCB footprints for ESP8266 modules
License: Other
In CvPcb or PcbNew when opening the libraries dialog i can't import the footprints, since kicad requires a .mod.
I tried renaming the files from _mod to .mod and add the folder as a search path. None worked
When I run design rules checker of KiCad PCB Editor I get two error related to the esp8266 footprint:
I'm new in the world of PCB design (so, can I have made some mistake somewhere), especially if I think no one have reported this issue since now.
Thanks!
I wonder why haven't you tried to push your symbols, models and footprints to KiCad.
I have interest in using ESP8266 but have not yet designed any circuit with it. I would love to see your models in the KiCad library for easiness of use.
I hope you find the idea appealing!
Nice work ;)
Open project, click "PCB Footprint Editor." Click "Select active library" then find "ESP8266" Click "Load footprint from library" then "List all" This results in the message "No footprints could be read from library file(s): in any of the library search paths. Verify your system is configured properly so the footprint libraries can be found." - Everything appears to be installed correctly, and I can use the components in a design, so what have I done wrong? Additionally, in the Library Browser (click "Open footprint viewer") no footprints show up under the ESP8266 library.
This is probably my own fault given that I don't know what I'm doing, but after a few minutes of compare and contrast, other libraries work. I've got this library installed at "Users\me\KiCad\Libraries" as per readme.md (also that spot makes sense to me).
Sadly I don't think the original author of this repo is maintaining it any more.
As some of the footprints fail DRC checks on current versions of Kicad, I have forked it and added some fixes:
https://github.com/Basirk/kicad-ESP8266
If anyone else wants to contribute, please do. I'll happily accept pull requests to the fork, but will be mostly trusting that people know what they're doing because I don't really!
Also note that I think the default Kicad footprint library now contains some ESP8266 modules under RF_Module. These weren't suitable for me as I wanted access to the pins on both sides of the board, and the Kicad version only had single-sided SMD.
It looks like the 3D model associated in this footprint is ESP-12.wrl when it should be ESP-12E.wrl.
Caveat: I'm an extremely novice kicad user JUST jumping in to 3D and have no idea what I'm doing. Also, on that subject: this library makes use of "${ESPLIB}" for defining the path to the 3D models. How does that work? Where does it get defined? I've installed this library with a "git clone" to Users/Me/KiCad/Libraries/kicad-ESP8266 (this is windows), and none of the 3D models get found until I manually add them at the footprint level with the absolute path... what am I doing wrong? I'd love a pointer.
Are the pin number on the ESP-01 part wrong? I'm thinking this can not be as this git repository has been active for over a year and I don't see any issues about this. That said, the ESP-01 pictures & diagrams I have found on the web show GND being pin 1. But when I placed the ESP-01 from the newly installed KiCad library GND was on pin 2.
This should also have a footprint and schematic symbol for the two chips (esp8266E and esp8285) without breakout/module board. Simply the bare chips.
ESP-02 is only one (except ESP-01 which is not possible to programming) module which was 2.54mm grid and is possible to use it on breadboard.
This is a great library, but unfortunately, I could not use them in KiCad 5.0 ( nightly build, Application: kicad
Version: (5.0.0-rc2-dev-744-gdfcdfe91f), release build)). When I tried (in eeschema) , I got an error saying it could not read the lib. If you want more specific information, I will re-install and try again. just let me know what you want to see.
With the coming release of KiCad 5.0, any chance of updating them for this release?
Any plans to add the ESP 12F?
IMHO, the NodeMCU1.0(12-E) footprint is too large. Aparently this is drawn for a LoLin V3 NodeMCU Board rather than the NodeMCU v1.0.
It's not quiet easy to find the correct dimensions on the web. According to this PDF, the outer board dimensions should be 25.4mm x 48.26mm:
https://github.com/nodemcu/nodemcu-devkit-v1.0/blob/master/NODEMCU_DEVKIT_V1.0.PDF
According to the caliper, my boards have exactly these dimensions.
See pictures of both boards here:
https://blog.squix.org/2015/03/esp8266-module-comparison-esp-01-esp-05.html
Could you add the ESP-12E board?
I want to build a custom dev board and that would be really helpful.
Thank you.
Would be great to also have a 3d model for the NodeMCU :).
going to add the esp8285?
Great library, thanks for the amazing work.
There's just one thing I've discovered. The PIN number order from 9 to 22 in the schematics does not correctly match to the one in the footprints.
The datasheet tells that pin ordering is the form of an U. It starts on top left on 1 then goes down the left edge (that part is okay). Then PIN 9 to 14 continue on the bottom edge and then go up again on the right edge from 15 to 22.
Here's the schematics (label ordering is correct, pin numbers are not)
Here's the footprint (numbering is correct, labels are not)
Pinout as it should be (unfortunately rotated by 180°):
Thanks for looking into it.
