NodeMCU-ESP32 Pin Connections

0:52

Below is the planned approach:

Add the NodeMCU ESP32 to your schematic (for example, assign it the designator U1).
Create net connections for each of its exposed pins to the corresponding PCB header pads using the default order. Based on the pads currently in your project, the mapping will be as follows:

Table

NodeMCU-ESP32 Pin	PCB Terminal (Header Pad)
Pin 1	Pin_8
Pin 2	Pin_1
Pin 3	Pin_12
Pin 4	Pin_13
Pin 5	Pin_6
Pin 6	Pin_15
Pin 7	Pin_11
Pin 8	Pin_4
Pin 9	Pin_3
Pin 10	Pin_7
Pin 11	Pin_2
Pin 12	Pin_14
Pin 13	Pin_9
Pin 14	Pin_5
Pin 15	Pin_10

With this mapping confirmed, the next step is to add the NodeMCU ESP32 to the schematic and then create schematic nets connecting each NodeMCU pin to its respective header pad as shown.

I've made a plan, and started work on it.

Plan

#Goal

Update the NodeMCU-ESP32 connection by replacing the obsolete 15-pin header with a new 19-pin 2.54 mm vertical socket/header, ensuring that all NodeMCU-ESP32 exposed pins are correctly connected to the corresponding PCB pads.

#Implementation plan

Discard the current 15-pin header connection:
1. Mark the published part 'Pin Socket 01x15 2.54mm Vertical' as obsolete or remove it from the editable project scope.
Create or select a 19-pin header:
1. Find or design a 19-pin 2.54 mm vertical socket/header in the parts library with pins numbered 1 to 19.
2. Ensure the footprint and symbol are correct for production-grade use.
Update the schematic with the new connection:
1. Place the 19-pin header in the schematic.
2. Connect the NodeMCU-ESP32 component pins to the corresponding 19 PCB pad pins in sequential order, verifying orientation and numbering.
Validate the design:
1. Run schematic and PCB checks ensuring all connections are correct.
2. Update the metadata and project name to reflect the 19-pin version.

#Success criteria

The obsolete 15-pin header connection is successfully removed from the project.
The new 19-pin header is correctly implemented with proper footprint and numbering.
All NodeMCU-ESP32 pins are connected to the corresponding 19 PCB pads in order.
Schematic and PCB validation checks pass without errors, and project metadata reflects the updated 19-pin configuration.
