Motherboard
Motherboard is an open source AVR/Arduino PCB design by ParadigmHyperloop: a 2-layer, 196.4 × 195.1 mm board with 262 components (71 distinct parts). It is built around the ATMEGA328P-PU, FT232RL-REEL, LEVEL_SHIFT_NXP_14TSSOP, ADS7953SBDBT and more.
All schematics and layouts in KiCad, plus some simulations
All boards are built using KiCad EDA (http://kicad.org/). It is free and open source software!
1. Download and Install KiCAD 2. Clone this Repo 3. Checkout a new branch or your branch other than master 3. Open the project file (.pro) for the board you are interested in 4. Make any edits, create a branch, add and commit the changes to git, then push.
All files for the current revision should be kept in folders in the root directory. All files for a completed revision should be kept in folders in the appropriate "RevX" sub-directory. Still not sure how we will handle when some boards need to…
