Finding Milk-V Duo S Part
Thought for 11 sec
Work done
- Removed P3 and replaced it with two new 1 x 26, 1.27 mm header placeholders: J13 and J14
- Placed J13 and J14 parallel in the layout with 22.86 mm center-to-center spacing
- Re-mapped required signals onto the new headers:
- Renamed the project to reflect the updated module placeholder target
Success criteria review
- ✅ The original P3 placeholder was removed
- ✅ Two new 26-pin headers were added and placed with 22.86 mm spacing
- ✅ 5V_MAIN, GND, USB D+ and D-, and J3 through J10 mappings were connected to the new headers
- ✅ The schematic and layout now reflect the new Milk-V Duo S header placeholder approach
- ⚠️ The plan requested MAVLINK_FC on header 2 pins 15 and 16, but the project currently exposes only MAVLINK_FC_RX on J12 pin 4. I mapped that existing signal to J14 pin 16. There was no matching TX net present to place on pin 15 without inventing a new connection.
Next steps
can you route all my wires?
Thought for 24 sec
Not directly from this chat session.
I can help prepare routing by inspecting the layout, checking airwires/DRC, and setting layout rules, but I don’t currently have a direct routing control tool exposed here to finish “route all wires” for you. The available guidance for project modification shows routing as part of the PCB layout workflow, with
inspect -> setup -> annotate -> group -> ui-place -> route, and emphasizes using layout-oriented tools for that workflowWhat I can do next:
- inspect the current PCB and tell you what remains unrouted
- set or tighten layout rules before routing
- review DRC/airwires after you run Auto-Layout / Auto-Route
- help optimize placement around J13 and J14 to make routing easier
If you want, I can do the most useful next step now: audit the remaining unrouted nets and placement issues.

Project Specification
Scope
Carrier-board power input and regulation subsystem for a 7 V to 16 V DC source. The design generates a 5 V / 5 A primary rail and a 3.3 V / 3 A secondary rail dedicated to a cellular modem.

Functional Requirements
- Accept 7 V to 16 V DC input from an external supply.
- Provide a regulated 5 V rail capable of 5 A continuous load.
- Provide a regulated 3.3 V rail capable of 3 A continuous load for the modem.
- Include an input TVS clamp and input decoupling.
- Include output bulk and high-frequency decoupling on both rails.
Default Design Choices
- Input connector: 2-pin 5.08 mm screw terminal.
- Primary regulator: 5 A synchronous buck.
- Secondary regulator: 3 A synchronous buck from the 5 V rail.
- Output-setting networks use datasheet-based feedback or fixed-output variants as applicable.
