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.~~ As of 2016/12/06 the pin numbers on the ESP-12E have been changed to be compatible with the ESP-12. If you need the old pin numbers they are still available on the oldNumbers branch.
ESP-07v2 - ESP-07 that is pin compatible with the ESP-12.
ESP-13-WROOM-02
There is a footprint for the ESP-06, but no supporting schematic symbol.

There are 3d models for the ESP-07v2, ESP-13, ESP-12 and ESP-12E.

WARNINGS

The symbols, footprints, and 3d models have not been tested. They are based on published images and measurements on individual samples.
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.

Use

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 https://github.com/jdunmire/kicad-ESP8266
```

Add ESP8266.lib to the Component Libraries:

eeschema:Preferences->Component Libraries->Add

Add ESP8266.pretty to the Footprint Libraries:

pcbnew:Preferences->Footprint Libraries Wizard

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 and then colored in Wings3D to produce the VRML (.wrl) format for KiCAD. Wings3D requires a binary STEP format, but OpenSCAD writes an ASCII version. meshconv will convert the ASCII format to a binary format.

Here is the workflow I used:

Use OpenScad to build the model. Export the model as STL.
- Build using F6
- File->Export...->Export as STL...

Use meshconv to translate the file to binary.

$ meshconv -c stl <STL-FILE-FROM-OpenSCAD> -o <FILENAME>

Now open Wings3d and import the the FILENAME.stl as a StereoLithography Binary File (*.stl).
Assign colors.
Export as VRML 2.0 File (*.wrl)
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
