A / EVERYDAY MODULE
Seeker shell
TPU perimeter, PC backplate, camera protection, exposed fingerprint/power control and two tapered receivers with replaceable POM liners. Target mass ≤48 g.
Solana Mobile Seeker · Engineering MVP · P0.2
A phone case that becomes a console.
A protective everyday Seeker shell locks into an optional clamshell performance dock with a thin thumb keyboard, shared battery and two detachable controllers.

Protection every day. Performance when wanted.
The phone keeps only a slim co-molded shell and reinforced receiver spine. Every moving, powered and serviceable component stays in the removable dock.
B / PERFORMANCE MODULE
Keyboard + battery + controllers
The full folding mechanism, BLE electronics, power system, 40–44-key board and two slide-out controllers remain together as one optional base.

02 · Packaging
One shared layer, not a stack of slabs.
The controller bays and central protected battery bay sit side by side under a 0.5–0.7 mm load-spreading plate. Typing loads route around the pouch cell.

03 · Mechanism
Detachable without a fragile laptop hinge.
Two 24 mm tapered receivers couple to a performance-dock torque tube. An over-center cam removes play; an independent safety blocks accidental release.

Magnets may help alignment but carry no credited structural load. The phone's USB-C connector floats on a replaceable flex and is never used to align or retain the device.
04 · Power
One battery powers the base, charges both controllers, and can charge Seeker.
Forward charging and phone output use separate power paths so keyboard and controllers remain active while the phone is powered.

Critical architecture rule: BQ25798 reverse OTG cannot run at the same time as its forward charging path. The MVP therefore specifies a dedicated boost and USB-C source controller for phone output.
05 · Candidate BOM
Every current part line, searchable.
This is a sourcing ledger, not a cost promise. Only 15 of 57 lines currently have defensible dated prices; custom mechanics, cells, PCBs, tooling and compliance remain open.

$63.01 known-price subtotal across 15 priced lines only. This is explicitly incomplete and excludes most custom, passive, PCB, tooling, certification and assembly costs.
06 · Open risks
The unknowns are part of the design.
P0.2 makes uncertainty visible instead of hiding it behind a polished render.
07 · Build path
Measure, prove, then refine.
- Scan/CMM three Seeker units
- Print cavity and fingerprint coupons
- Bench-test Hall controls
- Prototype trunnion + torque tube
- Discrete-switch keyboard fallback
- Power-path evaluation boards
- Custom PCB and FPC
- Qualified cell sample
- Thermal, RF, drop and life fixtures
Current truth: no physical prototype, production CAD, custom PCB, battery qualification, RFQ, tooling or certification has been completed. All fit-critical geometry remains gated on physical Seeker metrology.
