Built around the storage workflow
Electronics manufacturing
Manage storage monitoring for moisture-sensitive components, PCB assemblies and production materials.
Equipment integrators
Use editable electronics, firmware, wiring and cabinet CAD as the basis for cabinet customization.
From measurement to cabinet control
01 · Measurement
Two Vaisala HMP7 probes connect through isolated RS485. Temperature and humidity data feed the control and logging functions.
02 · Controller
ESP32-S3 handles settings, control requests, door events, local records and maintenance export.
03 · Interlock
ILIO24 and the active carrier condition control inputs and provide an enable latch and status interfaces.
04 · Power monitor
MON01 monitors the supply domains and provides voltage-window and power-good signals.
05 · Dehumidifier
An external DST RECUSORB DR-010B connects through the isolated control interface.
06 · Cabinet integration
STEP, DXF, mounting details, cable routes, terminal tables and the system BOM link electronics to the cabinet assembly.
| Board | Key devices | Role |
|---|---|---|
| DCAB v0.20 | ESP32-S3 | Dual probe acquisition, control requests, event records and export |
| ILIO24 R03 | TPS79850 / TPS3700 / SN74LVC3G17 | Field-supply conditioning and interlock logic |
| ILDOCK R03 | SN74LVC1G74 | Active carrier and enable latch |
| MON01 R02 | TPS3700 / TPS3808 | Supply-window monitoring and power-good signals |
Interfaces, control and service records
Measurement & communication
Dual HMP7 / isolated RS485 / temperature and humidity records. Probe connection and signal mapping are included in the hardware files.
Doors & control requests
Door events, dehumidification requests, damper-position inputs and interlock status are mapped in the point-to-point wiring table.
Storage & service
microSD records, RTC timestamps, USB Serial/JTAG maintenance and CSV export verification tools.
Two firmware packages
The main application uses the 0.15-dst profile. The interlock application uses 0.3-hw-latch. Each source package includes its pin mapping, build configuration, application images and associated technical records.

Open each image for a larger view. Editable board layouts and component data are included in the corresponding KiCad package.
Connect the electronics to the cabinet
Cabinet CAD R06 brings the board mounting, supports, cable paths and fastener geometry together. The R22 system BOM, R12 wiring and R06 terminal table provide a consistent material and connection index. The cabinet package includes the associated selection correction document.
STEP & DXF
Cabinet assembly, mounting plates, support geometry and hole projections.
Materials & wiring
System materials, PCB sub-BOMs, point-to-point wiring and terminal assignments.
Assembly references
Fastener stacks, tooling references, cable-end details and the terminal assembly guide.
