Improvements for the next major version 2.0

[sayanee]

Enhancements for Version 2.0

Schematic

• Use a single RGB LED for status indication
• Add multi sheet schematics for better readability
• Add component images and parameter graphs for better understanding
• Add a switch to turn on and off wireless communication to fallback to legacy functionality

Layout

• Use teardrops in KiCAD 8.0
• Add fudicial markers for pick and place
• Add silkscreen pin labels for all connectors that extend outside the PCB E.g. pin headers or USB-C
• Mistake-proof assembly by designing the case and PCB to fit only one way, E.g.asymmetric screw holes, PCB shape and screw lugs
• Add a header male pin (GND and VUSB/VBAT) to use with the nRF profiler for power consumption measurements

BOM

• Use a better quality slide switch DPDT for better tactile feedback

Case

• Make the text height bigger for LEDs and ON/OFF power switch
• Add more chamfers and rounded corners for a better aesthetic
• Teeth and groves - Make the teeth thicker for better strength
• Teeth and groves - Add a holder in the teeth so that the top and bottom cases do not slide
• Teeth and grooves - Include visual cues on the exterior for finger placement
• PCB holder screw lug can be shorter
• Add an LED slot to view the charge LED from the outside without opening the case
• Add filletted poles for screw lugs and holders on the case base
• Ensure the charging LED is visible from the outside through a slot or a transparent window
• Ensure the charging cable position on the case is accessible to the power socket on-site for charging
• Add more rounded corners and chamfers for timeless product design enclosures
• Following DFA (Design for Assembly), make the case easier to assemble by creating asymmetric screw hole positions on the PCB and case

Firmware

• (Firmware) Use OTA updates for firmware

Power

• Battery - Use a flat LiPo battery for a compact case design

Chore

• Use Conventional Commit Messages for better git history with scopes such as firmware, case, schematic, layout, docs, BOM, power, design, website, chore (CI/CD/updates).
