This Approximately Up wiring page separates the confirmed build → wire → fly → land loop from details that still need a current-build check. Approximately Up starts on Earth. Build modular ships in the garage, route Power and Data cables, fly first-person from inside your craft, land on Planet Stations to unlock permanent launch points, and complete delivery missions to unlock new components. Solo or up to four-player co-op on Steam. Use it as a garage-side reference, not as a promise that every unlisted binding, wattage, or thruster limit matches every patch.
The practical goal is simple: make one safer ship decision at a time, keep Power and Data intact after a crash, and turn a successful landing into a permanent Planet Station unlock. When a result is uncertain, rebuild near Earth and compare notes after you recover.

Power cables move energy. Data cables move signals. Controllers, joysticks, thrusters, radar, and automation blocks often need the correct mix of both. Community build guides repeatedly show red power ports and yellow/blue data ports — always confirm on the block tooltip in your build.
The reliable foundation is the same whether you fly solo or with a crew: start on Earth, bolt modular frames and thrusters, route Power cables for energy and Data cables for control signals, then pilot first-person from the deck. A ship that looks finished but has a dead battery or a missing Data path will not fly the way you designed it. That is why power wiring advice should start with ports, orientation, and a recoverable garage test rather than with a supposed optimal mega-build.
A useful first flight tells you what failed: an unpowered thruster, a reversed Data port, an atmospheric thruster used in vacuum, or an RCS battery that died mid-roll. It does not automatically tell you to enlarge the hull. Pause long enough to name the failure, fix the circuit, and decide whether the next test can stay near the pad.
This avoids a common early failure: the crew launches a huge Workshop import, crashes far from Earth, and then cannot tell whether the problem was mass, wiring, or thruster type. If the current craft becomes confusing, a smaller rebuild that lands once is a successful session rather than a wasted attempt.
In co-op, say the subsystem, the symptom, and the intended fix: “RCS pitch dead, battery empty, swap cell,” is more useful than a long description. Solo players can apply the same discipline as a mental checklist. The game rewards decisions that leave you a second option when the first thruster bank fails.
With that baseline in place, the next question is not “can we fly farther?” but “what does continuing cost if the circuit fails again?”
Wiring decisions should keep a circuit recoverable. Shared routers are safer than heroic spaghetti when you need to add one more thruster.
Use the table as a decision aid, not a hidden-stat calculator. Approximately Up has large modular ships and evolving community knowledge, so a precise number without an in-game check is less useful than a conservative threshold: protect a working circuit when recovery is uncertain, and test risky ideas only when you can still rebuild from a known station.
| Situation | Action | Why it is safer |
|---|---|---|
| A thruster is silent | Check Power reach first, then Data from the correct joystick/controller | No energy looks identical to no signal until you inspect ports |
| Batteries drain unevenly | Merge them onto a power router circuit | Isolated cells die while others sit full |
| Cables will not place farther | Community reports length limits — add a router or intermediate port frame and continue | Forcing a single span hides the real topology problem |
| You need automation later | Keep clean Data paths and labeled joysticks now | Hover and braking logic depends on readable signal chains |
Deleting a long cable run, launching with disposable batteries near empty, or committing to a Moon approach with no RCS reserve can remove options. Before doing any of those, confirm what the ship keeps if the attempt fails. If the answer is “a dead hull with no station unlock,” choose the reversible option first: rewire, test hover near the pad, or land at a closer Planet Station.
That same habit makes progress steadier. One secure station unlock can change every later rebuild; a speculative crash often repeats the same first minutes with no new parts.

Disposable batteries appear in community tutorials as non-rechargeable cells with built-in displays; solar panels are officially listed and used on longer routes to top up storage. Exact capacities and draws are build-specific — open the in-game readout rather than memorising a video number forever.
Avoid turning a single player report into a universal rule. A report can be valuable evidence of a wiring pattern, yet it may come from a particular unlock state, thruster mix, or patch. Record the context before copying it: which planet, which thruster types, whether Power and Data both reached the block, and whether the result was repeated after a rebuild.
A power router lets multiple batteries feed one thruster bank. Frame quarters with ports help you run Power and Data through the hull without spanning the exterior.
The useful follow-up is to connect this observation to the broader loop: does it make launch safer, reduce wiring confusion, change the Moon approach, or simply create a new risk? If it does not answer one of those questions, do not let it pull you into a larger hull before the current circuit works.
Sensors and RCS packages consume Power while flying. If attitude dies first, check those branches before blaming main lift thrusters.

Joysticks, RCS controllers, velocity meters, remappers, adders, and similar logic blocks talk over Data. Thrusters still need Power to push, but without Data they will not respond to the stick you think you are using.
A conservative guide is especially important while the live knowledge base is still growing. The Steam description confirms the broad systems—modular frames, Power and Data cables, atmospheric and electric thrusters, Planet Stations, missions that unlock parts, and up to four-player co-op—but it does not publish a complete numerical database for every block. Tables on this site therefore distinguish a confirmed loop from TBA details instead of filling gaps with invented wattages.
Community ship builds often use distinct data circuits so lift and cruise do not fight.
If the observed result matters to your next flight, verify it again after a patch or compare it with a concise report in the community. Keep the claim narrow: “this happened with this thruster layout” is more useful and more durable than a broad claim about every ship.
Clock-generator behaviour, full automation recipes, and complete watt tables stay TBA without verification.

Check the current build before treating a named binding, numerical power draw, channel name, exact thruster limit, or complete part roster as settled. The official Steam page is the source for the game’s core premise and player count; the verified Discord is the best route for patch-sensitive questions. Do not use copied invite links or anonymous “full databases” as authority.
Power feeds energy; Data carries control and sensor signals. Many parts need both before they work — but RCS thrusters pair wirelessly to an RCS controller; only the controller needs Power and Data.
It merges batteries and loads onto one circuit so thruster banks share energy instead of living on isolated cells.
No. Treat capacities and draws as build-specific — read them in-game. Unverified tables stay TBA.
No. This guide labels build-specific values, full part rosters, and unverified names as TBA rather than guessing.
Next: RCS guide. It continues the decision from this page into the part of the loop that keeps your next flight recoverable.
