About costs #260

image image These two chips only have different output currents in the manual. I would like to know if cheaper TPS65185 can be used instead of TPS651851 image

Roughly, if your panel size lower then 9", tps65185 is acceptable 小尺寸面板可以用65185

Indeed, they are functionally equivalent, except that the TPS651851 has better performance. Make sure to get the RSLR version though, because there is also an RGZ which has a larger package and won't fit.

Interesting issue! Since epdiy has now also a hardware repository I suggest that further issues about hardware can be discussed directly there. In my opinion the best would be to make a page in the WiKi section on the hardware side, that can be edited without making commits, etc (Or yes it does but internally and works just like a WiKi Content manager) and there we build a nice table with possible alternatives. Like @vroland mentioned above the most important thing is that the replacement part has the same footprint.

Proposed format in Hardware WiKi: https://github.com/vroland/epdiy-hardware/wiki/Alternative-components Feel free to expand and add a new column to the table if needed.

@martinberlin I think putting the wiki page into a markdown file that's also built into the pages website. That makes it easier for people to make a PR for that file to add new suggestions. In my experience, the wiki is also a bit hard to find.
