nk25719 / PMD___aka-KiCad-esp32-6leds-2switches-1pj-circuit-

In this repo I am practicing KICAD. Created an ESP32 DevKit V1 module and a PCB footprint. I designed a circuit around this ESP32 consisting of six lamps, four switches, and two power jacks and added a voltage regulater to Vin to maintain a supply of +5V. (This project was originally made of two switches and 1 power jack and was named homeWork2.)

Is your feature request related to a problem? Please describe. A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

This issue is simply to capture the typical behavior observed on a KiCad-esp32-6leds-2switches-1pj-circuit assembly during the ESP32 reset condition.

Typical Reset LED Behavior

image Only the power LED near J1 and the D8 LED are illuminated. D8 is not full brightness

Conclusion

If an assembly does not have this behavior suspect a hardware problem.

LED 8 is connected to D5

Lee found a schematic for by search on "schematic diagram for esp32 dev kit1 V1" See: https://embedded-systems-design.github.io/overview-of-the-esp32-devkit-doit-v1/ Look for schematic at this URL: https://embedded-systems-design.github.io/overview-of-the-esp32-devkit-doit-v1/SchematicsforESP32.pdf Detail showing the 10K pull up on D5 image

Conclusions

The soft illumination of the Diode D8 on the PMD when the system is in reset is behavior we can expect. There is no dangerous (no latent) failures of any hardware likely.

Closing this issues as explained. This information might be incorporated into a Factory Test document if one is ever written.
