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 thev080
. 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
-
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
-
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 -o
-
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, theShape 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 bymeshconv
.wings
- Wings3D model.wrl
- VRML model for KiCAD
