Gas Sampling Pump PCB Design

flux

I created the V1 pump design package without overwriting the existing NH3 loop-transmitter schematic.
Open items:
  • The current project already contains a complete analog NH3 4–20 mA transmitter, so I did not replace the schematic/layout.
  • To build the full pump schematic and PCB, I need confirmation whether to overwrite this project or create/fork a separate pump project.
  • Exact pump model/stall current and target board dimensions are still assumptions.
Suggested next steps:
  1. Confirm: replace this project or create a separate pump project.
  2. Provide the pump datasheet/model if you have one.
  3. Then I can capture the full schematic, run ERC, create layout/routing, and generate the final BOM/firmware/bring-up docs.

Yes, create a separate pump project and start the full schematic there.

I’ll create a separate pump project, then start schematic capture there so the existing NH3 transmitter stays intact.

flux

The new project is created: /mikaelle/gas-sampling-pump-pcb-design. I’ve started a dedicated schematic-capture thread there and will wait for its result before continuing verification/layout.

flux

Created the separate project and started schematic capture there: /mikaelle/gas-sampling-pump-pcb-design
Open items:
  • The schematic-capture thread is still running in the new project.
  • Layout/routing will wait until schematic/ERC is complete.
Suggested next steps:
  1. Open the new project to watch progress.
  2. Once schematic capture completes, ask me to review/fix ERC and continue to PCB layout.
