[Possible issue] DC-DC Converter inner pins not matching and Documentation request #9

Closed xF4m3 closed 7 months ago

xF4m3 commented 8 months ago

Hey, not sure if that is an issue in general or with the DC-DC Converter that i received.

For me only the outer 4 holes are close to identical(not perfect), but the 4 inner holes of the Converter do not fit, i can only get them to show a tiny bit if i shift the board a bit so that all 8 holes atleast are visible in the slightes. I do know that its not needed since the 4 inner and 4 outer holes are just a "mirror" of each other. But it would be nice if that could be double checked.

Of course it could also be diffrences in the DC-DC converters, but i used the ones that were linked in the BOM.

Additionally, i don't want to open a second issue just for that, but it would be nice if you could make a short description what each of the Jumpers do. Only JP2 is mentioned so far. maybe a small Table with all jumpers/connectors/headers and what they are for would be a nice addition. But i am mainly interessted what the jumper do aside from JP2.

The DC-DC Converter I received, have a perfect fit with the PCB. Could you post a picture?

I updated the readme to contain a table with component description: https://github.com/bagges/deye-esp32-bridge/commit/7357dff866de68883b9de0463fbbb4cc4467fbf4

I have already soldered everything and tried to align everything even if that means a hole is only visible 1/3, just tried to flush it with solder. But i just made some photos. You can see that the distance from inner to outer is about 2.5mm while on the dc-dc converter its about 3mm(only a rough measurement, as seen in the photos). So the outer holes are lining up pretty well, the inner holes are only visible about 1/3 and getting it positioned like that is a bit difficult. But since yours fit and i ordered the same, there might be a change in the production batch or i got a bad batch then?
