Design Review

Description

A project design will most likely contain some problems after first design draft is finished. Since we are all designing new things here all the time, let us help each other with reviewing the work done by others.

For myself I am able to review any design done with KiCad and Allegro or a C/C++ code done with Eclipse CDT. For a schematic design a PDF version will be sufficient most of the time.

If you think that you can help reviewing please invite yourself to the project. We will make the reviews to the best of our knowledge.

Please share ways how to improve this idea if you think it is worth working on

This has all the bells and whistles, so it'd be nice to get some more eyes on it.
It's exported from Upverter, which to be honest, I'm not particularly happy with the exported schematic view. Other than that, I quite like it. It also might have a transparent background, so you'll have to view in a new tab or something.
It's an ESP8266 dev board.
USB-UART bridge uses DTR and RTS to control the programming pins, NodeMCU-style.
Battery or USB, whichever is higher, feed the main voltage input. That goes to a SMPS, which a fixed 3.3v output, and an enable pin tied to a low-voltage cut-off for when the battery sags to around 2.8v.
USB power is also feeding a battery charger.
Thoughts? Suggestions?
Most of the semiconductors are also ones that are available through AliExpress, which to me, means the Chinese clone market is using them and they should remain cheap/good/available, and easy to scale up if I want to manufacture.

Cool idea. I had some really good experiences with community review before on www.reddit.com/r/printedcircuitboards

Neat project idea! I'm looking for feedback on my project. My recent post highlights areas I'm struggling with but to reiterate I'm not exactly confident in my power system. It's based around an LT3652 as a solar charge controller for a Li-Ion battery but will also need to be able to charge from USB.

Thanks!

I can review schematic/PCB designs in Eagle and Altium designer.

Where do we post projects? Just in the comments section?

I really like this concept by the way.

Either post in the comment or request to join and post it in the team chat. Will try to find a better way for this.

Seems like the most convenient way would be to request to join team, then post a project log with your design. Then we can comment on the log.
