HamShield1.1 Hardware
You can purchase HamShield (as well as smaller variants or LoRa version) at http://www.enhancedradio.com/
These are the hardware design files for the HamShield1.1 electronics.
Primary changes from the HamShield1.0b hardware are the RF switches that control what band is active. The entire shield is still compatible with the Arduino library.
These hardware files were created with KiCAD.
You may need the KiCAD libraries available here: https://github.com/mogar/KiCAD_libs When opening these projects in KiCAD, you may need to change the path to the libraries from the above link. This can be done in preferences->libraries in both the schematic editor and the layout editor. Make sure the libraries noted there point to wherever you put the above KiCAD_libs repo.
The Arduino Library for this project is available here: https://github.com/EnhancedRadioDevices/HamShield
