Power Pin Connection Issues
0:53
Running design review.
Analyzing the schematic.
Looking for "What is the function of pin VP on ESP32-DEVKIT-V1 / ESP32, and is it a power supply pin or an analog input? Return the exact pin role relevant to ERC missing power." in esp32_datasheet_en.pdf
This looks like a part-symbol pin type issue, not a real missing supply on U1.
- On the ESP32, VP = GPIO36 / ADC1_CH0 / SENSOR_VP
- It is an input-only analog pin
- It is not a power pin
So if Flux’s review says
[U1](https://www.flux.ai/:handle/:documentSlug?fit=U1):VP is “Missing Power,” the symbol is almost certainly classifying that pin incorrectly. In Flux, only actual supply pins should be typed as Power In; GPIO/ADC pins should be typed as signal pins insteadAlso, your review currently shows a second real power issue:
[U1](https://www.flux.ai/:handle/:documentSlug?fit=U1):VINis on Net 1 with[J1](https://www.flux.ai/:handle/:documentSlug?fit=J1)**:**Pin_3, but Flux still says that net is not driven- That usually means the source feeding VIN is not marked as a power source / power-output net
-
Ignore VP as a supply pin
- Do not wire VP to 3V3 just to silence the review.
- If you use VP, wire it only as an analog input.
-
Fix the underlying part definition
- Change pin type of
VPfrom Power In to Input or Unspecified - That is the proper fix for the false ERC
- Change pin type of
-
Fix VIN separately
- Make sure the source feeding
[U1](https://www.flux.ai/:handle/:documentSlug?fit=U1):VINis a real power source net, not just a passive connection from[J1](https://www.flux.ai/:handle/:documentSlug?fit=J1)
- Make sure the source feeding
- VP error = false positive from wrong pin type
- VIN error = actual power-source annotation/wiring issue
If you want, I can help you troubleshoot the VIN error next.
