Not all parts working properly
- Solar charging chip - due to chip layout
Assemble and test boards
- Work with Kenny to program boards
- Make note of what is not working properly
- Verify connections and voltage measurements
- Isolate hardware problems
Revise current design
- Recreate part library in EAGLE
  - Library for parts available, but not up to quality
  - Remake parts for more control with layout
- Must use 2 in. x 2 in. profile
- Freedom with layout
  - Incorporate 4 layer board
    - Tighter and cleaner layout, proper clearances
    - Isolate traces on top and bottom layers
    - Central layers ground and power
  - Alternate packages and parts - design preferences
    - Similar or better, worth cost?
    - Consider more efficient sizes/form factors
- Go through schematic, understand connections
  - How parts work with each other
- Create more professional schematic
  - Current schematic unprofessional due to layout
  - Group sensors, interfaces, communications, power, etc.
Documentation in schematic
- Current documentation lacking
- Currently no uniformity
- Provide labels and extra information (placement layouts, no empty pads, dedicate space)
- Effective use of space - no empty areas / wasted space
- Debug lines traced, Vias for power, etc.
- Resistance values shown for schematic
- Label part values
- Part layout at own discretion
  - Wire overlapping unwanted
- Microcontroller layout same as on board chip
  - Pins in order
  - Good documentation for software
Divide work between members
- Clean and update schematic
- Recreate parts
Jon will find board and assist with soldering QFN and small ICs
Manufacturing
- High quantity, cheap - Chinese vendor
- Quality, price not a problem - Advanced Circuits
- Quality, time - Bay Area Circuits
components
- Barometer, solar irradiance
- Solar charging chip
- Voltage regulators
- XBee
