Controls / Current architecture / mechanical interface / CONTROLLER-PLATFORM-V1
One platform. Three electronic roles.
Industrial supervision, deterministic tank control and reusable PoE sensing. Fixed carriers replace the oversized moving-board direction.
Retained development study. Dimensions, names and checks belong to this revision—not automatically to the retrofit-only product. Manufactured tank shells are deferred. No installation instruction, certification or manufacturing release is represented.
The source reasoning
Why this detail was investigated.
The current architecture separates application software from local process permissions and independent protection. Preferred components and mechanical interfaces are development choices, not a routed or physically qualified board.

The detail behind
the study.
Source-linked work for this revision. Reported checks describe the stated model or test; physical qualification and applicability to the current retrofit remain separate.
Current development baseline
Two manufactured tank families, SUB1500 and SUB2000, share a retrofit-capable treatment platform for qualified receiving tanks. Option A is accepted: individual pump and UV switching belongs in a protected, stationary tank-side power compartment; exterior Control supervises and provides upstream isolation.
| Role | Lead | Boundary |
|---|---|---|
| Exterior Control | Industrial NXP i.MX93 system-on-module; PHYTEC PCL-077 reference | Local interface, records, diagnostics and updates; no direct Linux or AI actuation. |
| Tank Hub | STM32H573 + DP83826AE PHY lead | Deterministic local permissions and feedback; independent protection is a separate design. |
| Common sensor endpoint | Reusable PoE receiver, network and conditioned front end | Custom sonar, floats and other sensors share electronics where useful, not one processor per passive contact by default. |
Features with an engineering purpose
Signed updates with recovery, scoped device enrollment, local incident recording, per-port network/power diagnostics, measured electrical-to-hydraulic response, offline USB-C service, and read-only diagnostic tools. These are specified targets; hardware and production firmware are not yet verified.
Six sensor ports means eight network connections
Allocate six sensor ports, one trunk uplink and one Hub CPU link. The eight-channel TPS23881 controls PoE power, not Ethernet switching. Full Type 1 Class 3 source allocation is 6 × 15.4 W = 92.4 W. With an assumed 12 W Hub overhead and 25% planning margin the low-voltage source screen is 130.5 W, excluding pump and UV lamp power. Exact supply, switch and thermal selections remain open.
3D geometry must follow engineering
The accompanying parametric source defines three preliminary board outlines and fixed removable carriers, with explicit dimensions and mounting interfaces. It does not fabricate chip geometry, a PCB netlist or a live mains enclosure. Import exact supplier models and the routed ECAD export before calling an assembly a populated production board.
Source generator: tools/control_platform/generate_mechanics.py. Configuration: contracts/hardware/control-platform.v1.json. Superseded appearance studies are removed from active navigation. Existing source-linked product geometry remains evidence, not an engineering release.
Release holds
Exact load data, switch/host interface, pin allocation, schematic, full MPN BOM, PCB routing, isolation, thermal/EMC, protective alarm architecture and physical fault testing remain required. No tank, treatment, disinfection, connector or electrical rating is granted by this update.
