READ BEFORE ORDERING
THIS BUILD.
THE IMPORTANT DETAILS.
- 2 Dock housings need new Tether attachment locations. Check the stud footprint, housing clearance and access to both Belt sockets at each original board location before buying.
- The 2 original strip-light location(s) use Micro Meteors in this proposal. Find 1×3 stud attachment points with 6.4 mm height clearance. Do not assume the old adhesive position will accept a housing.
- Capacity allowance: 7 Astro light/string connectors across 12 Dock Astro ports. This checks total capacity only. Assign lights by their actual locations and confirm each Dock’s local capacity and lead reach before buying.
- This is an independently derived component plan, not a physically tested installation or a replacement step-by-step instruction manual. Use the original guide together with the concordance and changed mounting/power plan.
Connection counts are a planning check. They do not verify local grouping, cable reach, power draw or physical fit. Astro ports and Belt sockets are different connections.
How the cable allowance was calculated
4 network components require at least 3 Belt links in this planning allowance. Original cable lengths are retained where mapped; included FX Belts are credited once. Extra links use 50 cm Belts as an unmeasured routing allowance. Check the actual branch and effect grouping against every source step.
THE CONCORDANCE
EVERY CHANGE.
IN PLAIN SIGHT.
Quantities below are individual components. The shopping list combines shared packs, then rounds up once.
| Original 1.0 item | Proposed 2.0 replacement | What to check |
|---|---|---|
| 4 x White 15cm Bit Light | 4 × Astro Light Regular - White 15cm ↗ | Keep one light at each original fixture. Route the flat lead without pinching it and confirm that its 15 cm lead reaches the chosen Dock. |
| 2 x White 30cm Bit Light | 2 × Astro Light Regular - White 30cm ↗ | Keep one light at each original fixture. Route the flat lead without pinching it and confirm that its 30 cm lead reaches the chosen Dock. |
| 1 x Cool White 30cm Large Bit Light | 1 × Astro Light Large - Cool White 30cm ↗ | Keep one light at each original fixture. Route the flat lead without pinching it and confirm that its 30 cm lead reaches the chosen Dock. |
| 2 x Warm White Strip Light | 2 × Meteor Light Micro - Warm White ↗ | One Micro Meteor per strip location. Its 1×3 Tether mount and 23.8×8×6.4 mm housing need different attachment and clearance. Fixture count is preserved; brightness and spread may differ. |
| 2 x 6-Port Expansion Board | 2 × Dock 6 ↗ | Astro ports are separate from the two Belt sockets. Mount the larger 2.0 housing with its included Tether; check the 1.0 board location has clearance. |
| 3 x 15cm Connecting Cable | 3 × Belt 15cm ↗ | Preserves the original nominal cable length. Belt plugs and routes differ; measure reach including bends before ordering. |
| 1 x USB Power Cable | No separate purchase | Power changes to a 60 cm USB Flux Belt and separately purchased manufacturer-specified 5V/2.4A supply. Old battery/USB alternatives are not added twice. |
| 2.0 USB power entry | 1 × Flux Belt 60cm ↗ | One Flux Belt per retained power group (old AA/USB alternatives combined). USB adapter or power bank excluded. Multiple sources must feed electrically separate networks; never join powered outputs. |
