Firmware
| Resource | Purpose |
|---|---|
| Cerberus USB Installer | Guided installation through the device USB connection |
| Cerberus Sentinel source | Application and built-in driver reference |
| Installer source | Public web installer and release metadata |
Use matched release images and each package's checksums and offsets. This reference does not copy firmware binaries into a second release channel.
Developer files
| File / folder | What is included | Status |
|---|---|---|
| Cerberus board pin header | S3 and onboard C5 signal constants | GPIO definitions |
| Read-only I²C identification example | Probe GT911/MAX17048 addresses and log ACK results | Standalone ESP-IDF example; hardware testing pending |
| Expansion breakout CSV | 25 GPIO signals with processor, printed label, and side; power and ground omitted | View from the labeled face; top to bottom on each side |
| Expansion breakout photo | Labeled face and GPIO group orientation | Full-size JPEG |
| Tested battery photo | Four tested packs and their printed labels | Full-size JPEG; see the battery list |
| Six-C5 WROOM expansion CSV | S3 CS slots and WROOM expansion SPI mapping | Expansion add-on still in testing; GPIO assignments only |
| Expansion KiCad area | Revision folders for expansion PCB/project files and footprints | Prepared; no CAD release uploaded yet |
The six-C5 bank is in testing. The RF/NFC add-on is in early testing and has no published pinout or download.
What belongs here
The repository accepts development documentation, reviewed pin definitions, examples, compatibility records, and explicitly identified expansion PCB files. Main-device schematics, PCB files, netlists, Gerbers, and board fabrication archives are outside this publication. Schematic files are excluded throughout the repository.
Before adding a manufacturing download, identify the exact expansion revision, supported Cerberus revision, connector orientation, KiCad version, license, and test status. Only mark a layout ready for fabrication when its review and validation records support that claim.
