**A comprehensive KiCad Library for the Raspberry Pi Pico** 🥧
|
|
====================================================================
|
|
|
|
### Providing footprints, symbols, and models for the module in its various forms and implementations
|
|
|
|
|
|
|
|
|
|
***Features***
|
|
==============
|
|
|
|
- **KiCad 7.0 support**
|
|
- **Schematics with alternate pin definitions** to select more specific behaviours for each GPIO, as well as specify power directionality
|
|
- **Generic and specific footprints** for the Pico and Pico W
|
|
- Through-hole and surface-mount footprints with and without mounting holes
|
|
- Hand-solderable test points (ie. USB signals) in footprints with underside castellations
|
|
- Optional pin labels as an add-on footprint
|
|
- Optional keepout zone for 2.4 GHz RF on shared footprints
|
|
- **Diverse 3D models** for surface-mount, through-hole, and socketed forms of the Pico, Pico H, Pico W, and Pico WH using photorealistic materials
|
|
- Majority adherence to the [KiCad Library Conventions](https://klc.kicad.org/) version 3.0.34
|
|
|
|
|
|
|
|
|
|
***How do I use this library?***
|
|
================================
|
|
|
|
- Ensure you are running KiCad 7.0 or later
|
|
- Download the most recent [release](https://gitlab.com/recursivenomad/ki-lime-pi-pico/-/releases/) of the library
|
|
- Unzip the file contents
|
|
- If not already created, create a new KiCad project
|
|
- Move the root library directory `RaspberryPi_Pico/` to a folder anywhere within your KiCad project
|
|
> *If using the library globally, move `RaspberryPi_Pico/` to a globally accessible location*
|
|
- Open the relevant KiCad project
|
|
- Select `Preferences > Manage Footprint Libraries...`
|
|
- Select the `Project Specific Libraries` tab
|
|
> *If using the library globally, select the `Global Librarires` tab instead*
|
|
- Click the folder icon in the lower left to `Add Existing`
|
|
- Navigate to and select `.../RaspberryPi_Pico/Module_RaspberryPi_Pico.pretty/`
|
|
- Click `OK`
|
|
- Select `Preferences > Manage Symbol Libraries...`
|
|
- Select the `Project Specific Libraries` tab
|
|
> *If using the library globally, select the `Global Libaries` tab instead*
|
|
- Click the folder icon in the lower left to `Add existing library to table`
|
|
- Navigate to and select `.../RaspberryPi_Pico/MCU_Module_RaspberryPi_Pico.kicad_sym`
|
|
- Click `OK`
|
|
|
|
To use, simply add a symbol to your schematic as you would any other; symbols should be located under the section `MCU_Module_RaspberryPi_Pico`, and footprints under `Module_RaspberryPi_Pico`.
