esp-12f pinout

5121 4

mchahn 3 years ago

I don't know if this is the right place to ask this but I'll give it a try. I added the ESP-12F(ESP8266MOD) (LCSC #C82891) to my design. It is a jlpcb smt part I'm using on my jlpcb board. The pins didn't look right and I looked at the datasheet linked from the LCSC page. The pin labels on the bottom and one side are totally wrong. I triple-checked with pinouts from multiple pages on the web. Should I trust what the datasheet says and replace the labels in my schematic? This makes me nervous. The pin labels could be wrong or the part number could be wrong which would be a giant problem. I know we are warned to not trust 3rd-party submissions, but this is from lcsc and jlpcb. What should I do?

First step is to select the part in the **Library** tool then right-click on **Report Error**. Include a link to the manufacturer's datasheet to support your description of the issue.

I found the problem. The pins were not numbered correctly. They were not consecutive around the part. That made the labels on the symbol not line up with the part. So using the labels on the symbol as provided would have worked but would confuse the heck out of anyone reading the schematic. I'll provide a fixed symbol and pinout.

@mchahn, Providing a fixed symbol and pinout only helps if @UserSupport, Support at LCSC and Support at JLCPCB copy it across into the apprpriate libraries. So you still need to post a Report Error. Otherwise it's just another User Contributed part that may get lost in amongst all the others. Giving it a unique name and a clear Description and a couple of Tags will help people find it but it being formally adopted into the main libraries is obviously better.

@andyfierman footprint link is footprint datasheet, not parts datasheet sometime, because the footprint is reuse, not every part has only one footprint, for example, SOP-8 we will mark its pdf link which we draw by the pdf size, but many parts can use this size footprint, and then they will binding this footprint when convert to PCB, the footprint link will be keep, then you will see it is incorrect with the part some symbol has the link property, when convert to PCB, its footprint's link will update to symbol's link, otherwise will keep the footprint's link footprint's link only for record this footprint size source, if we find out this footprint was incorrect size, we can use this link to fix it
