Software Has a Soul. Now Give Her a Body.
The FEAIA ecosystem has a new entry point starting today.
Olobay DollDock is officially live. It is the dedicated hardware parts platform built for the FEAIA virtual idol community — merchant-direct sourcing at market-lowest prices, a three-tier kit system for every skill level, a real-time compatibility engine, and a full DIY configurator for players who want to choose every component themselves. The goal is singular: bring your digital OC into physical reality, without spending weeks debugging hardware choices.
DollDock is not a generic electronics store. It does not try to compete with general marketplaces. It does one thing: helps you find the right part, and then shows you exactly what happens when you plug it in.
What Is DollDock? Positioning and Product Logic
Core Positioning
"Parts in place, companion present."
DollDock is an independent e-commerce station operated under the Olobay platform, positioned as the hardware integration entry point for the FEAIA virtual idol community. The problem it solves is specific:
When a player wants to map their Mates.ink or FEAIA digital character onto a physical desktop companion — one that sits on a desk, can nod, can speak, can feel a touch — three questions used to require separate research: where to source the parts, which specific parts to buy, and how to avoid incompatibilities. DollDock collapses all three into a single configuration page.
Relationship to the FEAIA Ecosystem
| Layer | Product | Role |
|---|---|---|
| Software | FEAIA / Mates.ink / Mates.beauty | AI character, emotion engine, OC identity |
| Firmware | TrayTool | Hardware driver, device communication, activation |
| Hardware | DollDock (new) | Parts direct sourcing, kit configuration, DIY support |
DollDock is the missing final layer of this vertical ecosystem. Purchasing any hardware kit automatically generates a TrayTool activation code at checkout — hardware online means software activated, no extra steps.
Three Kits: From 30-Minute First Boot to Full Flagship
DollDock offers three turnkey kits for players at different levels of commitment. All kits are direct-from-merchant priced, containing certified and compatibility-tested full BOMs (bills of materials).
First Touch · Lite — ¥299
For: First-time AI doll hardware builders who want a fast, confident first boot.
Core configuration:

The radar detects you walking in from 5 meters away. The joint system lifts her head as you enter. Metal gears hold their position without slipping.
The OC Configurator: Three Parallel Tracks
DollDock's core experience is not browsing shelves — it is the OC Builder configurator.
SimpleTrack · One-Tap Channel
For entry-level players: choose Lite / Standard / Pro on the landing page, complete the order in three steps. The configurator automatically matches all certified-compatible components. From page entry to order submission: as fast as 90 seconds.
BuildTrack · DIY Configuration Channel
For intermediate players: a 7-step configuration flow with individual module selection:
- Base kit (choose starting point: Lite / Standard / Pro / blank custom)
- MCU module (ESP32-S3 series, 3 variants, with PSRAM comparison and AI inference capability notes)
- Display module (round IPS display / LED ring eyes, including AR-coated vs. standard comparison)
- Audio module (microphone + amplifier + speaker, configured as independent input/output)
- Sensing module (touch / posture / environment sensors, freely combined)
- Extension module (joint system / radar presence / CO₂ sensor, all optional)
- Confirm and software activation (BOM summary, price total, TrayTool activation code explanation)
Each step offers Simple mode (default: shows 2–3 official recommended options) and Expert mode (full SKU listing with complete spec tables, GPIO budget calculator). Modes switch instantly with no page reload; selections and state are preserved across switches.
ProTrack · External Comparison Channel
For experienced buyers: add any product to the Compare Dock (up to 4 items simultaneously), specs aligned by row, differences highlighted. Supports adding directly to cart from the comparison view.
Parts Catalog: 10 Functional Modules, Full AI Companion Coverage
DollDock organizes its parts by companion body function region, not by electronic component type — meaning even players with no electronics background can navigate by asking "what capability do I want her to have?"
| Functional Module | Companion Capability | Representative SKU |
|---|---|---|
| MCU (Heart) | AI inference, memory, networking | ESP32-S3-N16R8 |
| Display (Eyes) | Expression animation, emotion visualization | GC9A01 round display |
| Microphone (Ears) | Voice recognition, direction sensing | INMP441 dual-mic array |
| Amplifier + Speaker (Mouth) | TTS voice playback | MAX98357A + 36mm speaker |
| Touch (Skin) | Interactive touch zone sensing | MPR121 + conductive fabric |
| Sensors (Sense) | Environment, posture, presence | SHT40 / MPU6050 / LD2410S |
| Lighting (Glow) | Emotion body ring, lip-sync LEDs | WS2812B series |
| Power (Energy) | Charging management, battery runtime | TP4056 + LiPo |
| Servo Joints (Joints) | Physical head/arm movement | MG90S × 4 + PCA9685 |
| Accessories (Misc) | Structural parts, cables, enclosures | Continuously updated |
Real-Time Compatibility Engine
The configurator includes a built-in validation engine that checks seven common error types before checkout:
- MCU insufficient PSRAM (incompatible with Pro-level AI inference)
- Amplifier/speaker power mismatch (5W amp + 3W speaker damages the speaker)
- Conductive fabric selected without MPR121 touch controller
- Servo pack selected without PCA9685 driver board
- Lite LED eyes and GC9A01 round screen selected simultaneously (conflict)
- Servo system without LiPo battery (USB power may reset MCU under servo load)
- Recommendation prompt (mouth arc LEDs for complete lip-sync experience)
All validation runs locally in real time — no server round-trip, no latency, conflicts flagged immediately as you configure.
Merchant-Direct Sourcing and Pricing
DollDock operates on a merchant-direct storefront model, not platform resale. Current certified merchants:
| Merchant | Certification | Ships From | Lead Time | Return Policy |
|---|---|---|---|---|
| Olobay Official | OFFICIAL (Lv.4) | Shenzhen | 1–2 days | 7-day no-questions |
| FlashDrive Electronics | CERTIFIED (Lv.3) | Guangzhou | 1–3 days | 7-day no-questions |
| XinCore Modules | VERIFIED (Lv.2) | Suzhou | 3–5 days | Quality issues |
Certification levels explained:
- OFFICIAL: Complete compatibility testing by the Olobay engineering team; all FEAIA features confirmed; drivers built into official firmware
- CERTIFIED: Passed DollDock compatibility validation suite; confirmed functional with recommended kits
- VERIFIED: Basic compatibility validation passed; suitable for experienced builders who can evaluate edge cases independently
All prices are set directly by merchants. DollDock does not mark up products or take a commission on goods — what you see is the actual source price. When a product is available cheaper on an external platform, the Compare Dock actively shows the external link (transparency-first principle).
My Dock: Configuration Archive and Repurchase System
Logged-in users access a personal "My Dock" (/dock) space:
- My builds: complete visual configuration of every purchased kit (live preview rendering)
- Parts inventory: current parts holdings (entered via activation code scan or manual input)
- Saved configurations: incomplete build drafts, shareable as unique short links
- Activation records: TrayTool activation codes and expiry status
- Order history: one-tap repurchase, automatic low-stock notifications
Configuration sharing: every saved build generates a unique short link (dolldock.com/build/xxxxx). Recipients can use that link as their starting point in the configurator and modify from there — the original build is not affected. Share your verified companion configuration directly with a friend; they buy from your validated starting point.
Frequently Asked Questions
Q: How is DollDock different from buying parts on general marketplaces?
Every part on DollDock has been tested for FEAIA compatibility by the Olobay engineering team, and its certification level is displayed in the configurator. General marketplaces carry the same chip model numbers, but cannot guarantee firmware-level driver compatibility or that GPIO pin assignments won't conflict with FEAIA TrayTool. DollDock's core value is "buy it, it works — no debugging required."
Q: Does the Lite kit really require no soldering?
Yes. The Lite kit uses entirely pre-soldered modules (development boards and sensors with pins already attached), connected via DuPont wire or JST connectors following the included wiring diagram. Standard and Pro kits include some assembly steps for advanced components (servo mounting, enclosure fitting), but the electrical connections throughout require no soldering.
Q: I already have some parts. Can I only buy what I'm missing?
Absolutely. The BuildTrack configurator supports starting from a blank slate with complete free-form selection. Choose any combination of individual SKUs; the compatibility engine validates your combination in real time. Nothing forces you to buy a full kit.
Q: How do I receive my TrayTool activation code after purchase?
The activation code is generated automatically and displayed on the order confirmation page, and sent via email simultaneously. Activation steps: in your installed TrayTool, go to About → Activate, enter the code, complete in 30 seconds.
Q: Does the Pro kit's joint system require advanced technical skills?
Pro kit assembly includes mounting MG90S servos, installing the PCA9685 driver board, and wiring the STM32G031 coprocessor. Physical installation requires some structural modification of the companion body (drilling, fixing mount points). DollDock provides illustrated installation guides and video tutorials for each step. The official Discord hardware channel also provides real-time installation support from community members and the Olobay team.
Q: What payment methods does DollDock support?
Currently WeChat Pay and Alipay — no card number entry required, native payment dialogs. International card support is planned for a future update.
