Retrieved the required internal execution checklists for schematic/layout/constraints so the next edits follow Flux procedure .
Success criteria review
❌ Two separate Flux projects were not created (I only have access to the single current project context).
❌ Analog + digital schematics were not yet built (no components/nets placed/wired).
❌ DF40 interleaved-GND pin map not yet instantiated/documented in-project.
❌ 4-layer stackup + layout rules not yet configured.
Next steps
Please create (or share links to) two empty Flux projects named EEG Analog and EEG Digital, or confirm you want me to proceed inside this single project first (and later duplicate/split).
Once you confirm, I will: (1) set each project description, (2) add the DF40 connector(s) and define the pin map, (3) add/place the required ICs, passives, and protection parts, (4) wire shared SPI with per-AFE CS/DRDY plus shared START/RESET, and (5) set 4-layer stackup + initial layout rules, then check ERC/DRC.
Documents are markdown text files which describe project goals, capture details, or even simulation outputs.
Assets
Assets are files uploaded to this project which can be used in various ways.
Two-PCB low-noise EEG system: Digital board (ESP32-S3-MINI-1U + ADS1299 + CP2102N + USB-C + 1S Li-ion charger/power-path + DF40 mezzanine) and Analog board (3x ADS1299 + REF/BIAS/DRL + driven-shield electrode interfaces + local low-noise regulation + test points). DF40 mezzanine carries only power + digital SPI/control with shared SPI, shared START/RESET, and separate CS/DRDY per AFE. 4-layer stacks with strong analog/digital partitioning and interleaved GND pins on DF40.
