kicad-ESP8266 - a library for KiCAD
|
||
|
|
=====================================
|
||
|
|
This project has both schematic symbols, footprints, and 3d models for
|
||
|
|
ESP8266 based modules. It is a work-in-progress. Additions and
|
||
|
|
corrections are welcome. Enter a pull request or file an issue on
|
||
|
|
GitHub.
|
||
|
|
|
||
|
|
The present modules are:
|
||
|
|
|
||
|
|
* ESP-01 - Note that there are two versions of this module available on
|
||
|
|
open market. The schematic symbol is for the `v090` version
|
||
|
|
which is probably the same as the `v080`. There is an older
|
||
|
|
version that does not include any GPIO signals. The footprint
|
||
|
|
is the same for all of the ESP-01 modules.
|
||
|
|
|
||
|
|
* ESP-12 - This is includes an alias part, ESP-07v2, that is suitable
|
||
|
|
for the 16 pin variant of the ESP-07. Note that there is a 14
|
||
|
|
pin version of the ESP-07 that has different signals and
|
||
|
|
pinout. The footprint for the ESP-12 (and ESP-07v2)
|
||
|
|
elongated through-hole pads to match those modules.
|
||
|
|
|
||
|
|
* ESP-201 - This is a 26 pin module with pins on 0.1 inch spacing. I
|
||
|
|
could not find any official measurements for the pin
|
||
|
|
locations so the footprint was created from empirical
|
||
|
|
measurements on the unit I have.
|
||
|
|
|
||
|
|
* ESP-12E - This is for the 22 pin variant of the ESP-12. Though all the
|
||
|
|
esp-12 signals are in the same place on ESP-12E, pin numbers
|
||
|
|
have changed.
|
||
|
|
|
||
|
|
There are 3d models for the ESP-12 and the ESP-07v2.

WARNINGS
|
||
|
|
---------
|
||
|
|
1. The symbols, footprints, and 3d models have not been tested. They are
|
||
|
|
based on published images and measurements on individual samples.
|
||
|
|
|
||
|
|
2. The `.dcm` file contains HTML links to information on sites I used
|
||
|
|
when creating this library, however I do not have any control over
|
||
|
|
the sites themselves. Follow the links with caution.
|
||
|
|
|
||
|
|
3. This library distributed in the hope that it will be useful,
|
||
|
|
but __WITHOUT ANY WARRANTY; without even the implied warranty of__
|
||
|
|
__MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE__.

|
||
|
|
1. Clone this archive to a convenient location on your computer. These are
|
||
|
|
the commands I use on Linux to create a copy in
|
||
|
|
`~/kicad/libraries/kicad-ESP8266`:
|
||
|
|
|
||
|
|
mkdir -p ~/kicad/libraries/
|
||
|
|
cd ~/kicad/libraries/
|
||
|
|
git clone
|
||
|
|
|
||
|
|
2. Add `ESP8266.lib` to the Component Libraries:
|
||
|
|
|
||
|
|
eeschema:Preferences->Component Libraries->Add
|
||
|
|
|
||
|
|
3. Add `ESP8266.pretty` to the Footprint Libraries:
|
||
|
|
|
||
|
|
pcbnew:Preferences->Footprint Libraries Wizard
|
||
|
|
|
||
|
|
4. To make the 3d models usable, add the location from step #1 to list
|
||
|
|
of configured paths as `ESPLIB`. Use a full path. Continuing with
|
||
|
|
the example step #1:
|
||
|
|
|
||
|
|
kicad:Preferences->Configure Paths->Add
|
||
|
|
|
||
|
|
Name: ESPLIB
|
||
|
|
Path: /home/<your_login_name>/kicad/libraries/kicad-ESP8266
|
||
|
|
|
||
|

|
3D Models
|
||
|
|
---------
|
||
|
|
The 3D models were built using [OpenSCAD](http://www.openscad.org/) and
|
||
|
|
then colored in [Wings3D](http://www.wings3d.com/) to produce the VRML
|
||
|
|
(`.wrl`) format for KiCAD. Wings3D requires a binary STEP format, but
|
||
|
|
OpenSCAD writes an ASCII version.
|
||
|
|
[meshconv](http://www.cs.princeton.edu/~min/meshconv/) will convert the
|
||
|
|
ASCII format to a binary format.
|
||
|
|
|
||
|
|
Here is the workflow I used:
|
||
|
|
|
||
|
|
1. Use OpenScad to build the model. Export the model as STL.
|
||
|
|
* Build using F6
|
||
|
|
* File->Export...->Export as STL...
|
||
|
|
|
||
|
|
2. Use `meshconv` to translate the file to binary.
|
||
|
|
|
||
|
|
$ meshconv -c stl <STL-FILE-FROM-OpenSCAD> -o <FILENAME>
|
||
|
|
|
||
|
|
3. Now open Wings3d and import the the `FILENAME.stl` as a
|
||
|
|
_StereoLithography Binary File (*.stl)_.
|
||
|
|
|
||
|
|
4. Assign colors.
|
||
|
|
|
||
|
|
5. Export as _VRML 2.0 File (*.wrl)_
|
||
|
|
|
||
|
|
6. The 3D model probably needs to be scaled to match the footprint. Use
|
||
|
|
the `kicad:Footprint Editor:Edit->Edit Properties->3D Settings`
|
||
|
|
dialog. For the ESP-12, the `Shape Scale` X, Y, and Z values are
|
||
|
|
0.393700.

||

This repository includes all the intermediate files:
|
||
|
|
|
||
|
|
* `.scad` - OpenSCAD model
|
||
|
|
* `.stl` - OpenSCAD STL
|
||
|
|
* `_4wings.stl` - STL file converted by `meshconv`
|
||
|
|
* `.wings` - Wings3D model
|
||
|
|
* `.wrl` - VRML model for KiCAD
