Martin ROGER / VXDash - History

Housekeeping update - 1.2.2

Version numbers updated to 1.2.2 for the schematic and PCB
Components identified, datasheet and descriptions updated
iBOM regenerated
PCB plots regenerated
PCB :
- only thermal reliefs on PTH, not on SMD pads

- couple rationalisations on the 3v3 rails

Updated 12V to 3V3

Simplified 12V to 3V3 switcher

Fonts reshape

Stress testing might be a bit too stress intensive, so next stages are :
- [ ] Implementing quantization
- [ ] Implementing limited Serial traffic

Initial stress testing program running

A lot of segmentation on long progress bars doing fast sweeps (like RPM for example
No value-repetition check on maths that are being sent over
Monospaced fonts are a must

commit 0abb7f70bfd32a1cf75c841c40817ddc2e84700f
Author: Martin <martin.roger@me.com>

Added first draft of Op-amp based circuitry

Also some rationalisation of the components to avoid near-duplicates (e.g. 0.1uF 50V caps)

Continued merge of both branches

Cleaned up PCB, extended 10mm to the right and pushed the power conversion stages to the right of the board.
Left Resistive sensors out in the open as they will be changed, increased available real estate for resistive sensor

1.1HW and Schematics -> PR

- Updated all dates in title blocks
- Added both FET based new power supply and protection circuits - completely winged the zones
- Completed PCB layout, passes DRCs --> Needs review
- Updated PCB metadata
- Relocated 5th mounting hole a bit
- Regenerated interactive BOM

Power conversion split, work prep

-3V3 supply now in parallel with 5V stage
- Reorganisation of hierarchical sheets
- WaterT sense is indeed a PWM so is singled out in the hierarchical sheet
