Chceš doplniť 12 V napájanie, konektory pre senzory, relé, I2C a merací vývod podľa presného zapojenia, ktoré si poslal.

Pridal som plán pripravený na vykonanie.
Zahŕňa batériový vstup, 4 senzory na A0-A3, relé na D2-D5, 2x I2C header na A4/A5 a vývod pre meranie +12V_BATT.
Súčasťou je aj kontrola footprintov, PCB dopadu a ERC/DRC.

Plan

#Goal

Implement a 12 V battery powered Arduino Uno based system featuring multiple connectors: a 2-pin battery terminal block feeding +12V_BATT and GND (with +12V_BATT tied to VIN), four 1x03 headers for moisture sensors (mapped to 5V, GND, and A0–A3), one 1x06 header for a relay module (mapped to 5V, GND, and D2–D5), two 1x04 headers for I2C connections (mapped to 5V, GND, SDA, and SCL using A4/A5), and a 1x01 header for INA226 VBUS measurement (tied to +12V_BATT).

#Implementation plan

Battery Input and Power Distribution:
1. Add a 2-pin terminal block for battery input with nets labeled +12V_BATT and GND.
2. Connect the +12V_BATT net directly to Arduino Uno’s VIN pin, ensuring the battery voltage feeds the onboard regulator.
Moisture Sensor Headers:
1. Add four 1x03 headers.
2. Map each header’s pins to 5V, GND, and individual analog input pins A0 through A3 respectively.
3. Validate that these headers have proper footprint and orientation to fit the board layout.
Relay Module Header:
1. Add a 1x06 header.
2. Map its pins so that one pin connects to 5V, one to GND, and the remaining four to digital pins D2 through D5.
3. Confirm correct spacing and alignment for PCB manufacturability.
I2C Headers:
1. Add two 1x04 headers for I2C.
2. Connect each header’s pins to 5V, GND, SDA (Arduino A4), and SCL (Arduino A5).
3. Ensure that both headers share the same I2C bus and maintain proper clearances with other components.
INA226 VBUS Measurement Header:
1. Add a 1x01 header.
2. Connect it directly to the +12V_BATT net for INA226 VBUS measurement.
Validation and Layout Impact:
1. Review and update the schematic to confirm all required nets and connections are correctly assigned.
2. Validate connector properties, such as footprint dimensions and pin spacing, to ensure compatibility with the PCB layout.
3. Run ERC/DRC checks to confirm no connectivity conflicts remain.
4. Assess PCB layout for clearance, component placement, and manufacturability to avoid area congestion near connectors.

#Success criteria

Battery terminal block +12V_BATT is correctly routed to both VIN and INA226 header.
Four moisture sensor headers provide dedicated access to 5V, GND, and analog inputs A0-A3.
Relay module header is correctly wired to supply 5V, GND, and digital outputs D2-D5.
Dual I2C headers are properly connected to 5V, GND, SDA (A4), and SCL (A5).
All connectors have verified footprints, proper clearances on the PCB, and successful ERC/DRC validation.

how to edit permision to start

If you mean edit permission for the project so you can click Start / make changes, I can’t change sharing/access for you. In Flux, changing project sharing permissions is a human-only action, and my capabilities only cover design/project edits, not access control. The modification tools cover plans and project edits, but not permission management .

Also, in your current context, you do not have edit access to this project, so that is likely why you can’t execute the plan.

What to do:

Open the project owner’s sharing/settings controls
Ask the owner to give you edit access
Then reopen the project and you should be able to use Start

If this is your project and you’re trying to find the exact sharing UI, tell me whether you want:

how to change project sharing permissions, or
how to fork/clone this project into your own editable copy

Since you don’t currently have edit access, the fastest path is usually to fork/clone it into your own project if that option is available.

How do I fork?
