I've put several updates on the Fritzing file, but I'm going to wait a bit before I update the graphic.
Among the changes:
- Adjusted the width and positioning of the leads to the MAX11312, MAX4468, and MCP4462 so there are no shorts or other issues (as determined by Fritzing's Design Rules Check function).
- Fiddled with several of the traces to make them shorter (saving copper and reducing resistance).
- Added a Qwiic connector. You can never have too many Qwiic connectors.
- Also added a pair of 2-pin headers so the mike and speakers can be connected internally. This could be done with short headers, or with right-angle headers.
- Moved the 24LC32 to allow for the right-angle header on the Mic connector.
I want to do a bit of research (or get a bit of feedback) on how much clearance I'll need for the Spkr connector before I move the NCS2211 (along with C17-18 and R21-22). Once that's all done, I'll update the Fritzing file again, and the graphic with it. (This upload is mainly to make sure that the above changes are backed up!)
Meanwhile, this is looking about ready to figure out the BOM so I can (eventually) send it off for fabrication. I probably should also start figuring out the Python code.
