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
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
ESP-07v2 - ESP-07 that is pin compatible with the ESP-12.
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.
The symbols, footprints, and 3d models have not been tested. They are based on published images and measurements on individual samples.

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
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.
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).
Export as VRML 2.0 File (*.wrl)
The 3D model probably needs to be scaled to match the footprint. Use
kicad:Footprint Editor:Edit->Edit Properties->3D Settings
dialog. For the ESP-12, the
Shape Scale X, Y, and Z values are
This repository includes all the intermediate files:
.scad- OpenSCAD model
.stl- OpenSCAD STL
_4wings.stl- STL file converted by
.wings- Wings3D model
.wrl- VRML model for KiCAD
