Daily snippet

• Changed daughterboard pinouts in schematics support PMOD I2C interface.
• Looked at the possibility of using bidirectional isolators in data isolation stage, but it was ruled out as they were found to be expensive.
• Re-justified use of data isolation stage in serial expansion motherboard.
• Created new kicad modules (footprints)
• Completed footprint association of components on motherboard schematics using CvPcb
• Verified footprints for components and checked 0603 footprint to be imperial type instead of metric type. Checked datasheets of all components to make sure correct footprint is assigned to them.
• Made sure only low current (2mA) LEDs are used.
• Fixed hole dia and added shield pins in VHDCI module
• Just started with PcbNew, will be creating new module for the daughterboard slot and start laying them out nicely.
