A KiCad library for shields for Alchitry fpga boards.
This library is made for KiCad 6 and above.
This library contains the following symbols:
- Alchitry_Element_CU
- Alchitry_Element_AU
The Pin names (inside the box) correspond to the actual hardware pins of the FPGA's. If you are using Alchitry Lab's or have a constraints file with the pin numbers according to Alchitry just look at the pin numbers (above pin).
All footprints already contain the correct board outline and mounting holes. The mounting holes are 2.2mm in diameter and are designed for M2 screws.
This library contains the following footprints:
- Element
- Element_no_top
The Element_no_top footprint is the same as the Element footprint but without the top connector. This is useful if you don't plan on stacking anything on top of your shield.
When using the normal Element footprint it is best to use it with the provided template project. This project has all the via's and traces for connecting the top connector to the bottom connector.
- Clone this repository into your KiCad library folder
- Go to
Preferences -> Manage Symbol Libraries... - Click the folder icon and open the
Alchitry_Element.kicad_symfile from this repository - Click
OK - Go to
Preferences -> Manage Footprint Libraries... - Click the folder icon and open the
Alchitry_Element.prettyfolder from this repository - Click
OK
All Done! You can now use the Alchitry Element symbols and footprints in your KiCad projects.
The needed connectors to interface with the Alchitry boards are:
- PRT-16891 (Top Connector)
- PRT-16890 (Bottom Connector)
They can be found on mouser, digikey, and sparkfun.
I have also attached a pin Reference for the Alchitry Au in the attachments folder.
