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 GND islands taken care of
- couple rationalisations on the 3v3 rails

PCB layout update 1.2.1

Updated with OpAmp circuitry plus some component identification

Minor SW release

- Added foundation functions and debug mode
- Renamed some ESP32 inputs
- Completed some SMD footprints that were missing

PCB update to be done

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

PCB updates for power input and 5V regulator

Updated footprints and PCB layout for new power input and modified 5V switching regulator.

Updated 5V switching reg circuit

- Changed input and output capacitors.
- Modified EN and FB resistor values to match datasheet calculations.
- Changed inductor to higher current rated part.

v1.0

- First PCB layout publication
- Titled schematics
- Added Revisions to Schematics and PCB
- iBOM release
- PDF export of PCB design
