Customer:
Do you have a schematic for your MCP4725 breakout board? I’m trying to figure out what the extra components are for.

The open source hardware files are available here: GitHub - SolderedElectronics/DAC-6-bit-1-channel-MCP47A1-breakout-hardware-design: Hardware design, BOM, gerbers and 3D files for DAC-6-bit-1-channel-MCP47A1-breakout designed by Soldered Electronics. · GitHub
There doesn’t appear to be a schematic publicly available yet. A schematic has been exported from the KiCad files and is attached.

Customer:
The schematic I need is for the DAC Breakout MCP4725, not the 6-bit MCP47A1 board. The Soldered website has a small error that confuses MCP4725 with MCP47A1. I definitely have the MCP4725. The board is working great over I2C, but I’ll be using it with an external supply soon and wanted to understand the component layout.

That was the old product version without publicly available documentation. A schematic for the MCP4725 breakout is attached.
