If you tell me which LED you prefer (or “pick the most available”), I can swap the generic parts in your power-LED branch to these exact 0603 parts and keep the wiring 3V3 -> R -> LED -> GND.

You’re right: I did not add anything yet. My earlier message was just describing what would be added, but nothing changes in your project until the plan is executed.

I’ve now created an executable plan to add the always-on power LED:

Add a 0603 green LED and a 330 ohm 0603 resistor
Wire 3V3 -> R -> LED -> GND
Set designators/properties and ensure it shows up in PCB + passes checks

Click Start on the plan bar to apply it. If you want, tell me which exact LED/resistor MPN from the options we found, and I’ll bake those into the plan before you run it.

This project involves the Seeed Studio XIAO nRF52840 Sense board, a device that combines the nRF52840 microcontroller and some sensors, along with Bluetooth 5.0 wireless capability; it is primarily designed for low-power applications like Internet of Things (IoT) and embedded Machine Learning.

As per the information provided, it appears that there are no nets currently in this project - it's a list of the board's pin designator names along with their corresponding pin numbers:

P0.02_A0_D0 (Pin Number: 1)
P0.03_A1_D1 (Pin Number: 2)
P0.28_A2_D2 (Pin Number: 3)
P0.29_A3_D3 (Pin Number: 4)
P0.04_SDA_A4_D4 (Pin Number: 5)
P0.05_SCL_A5_D5 (Pin Number: 6)
P1.11_TX_D6 (Pin Number: 7)
D7_RX_P1.12 (Pin Number: 8)
D8_SCK_P1.13 (Pin Number: 9)
D9_MISO_P1.14 (Pin Number: 10)
D10_MOSI_P1.15 (Pin Number: 11)
3V3 (Power source; 3.3V - Pin Number: 12)
GND (Ground reference - Pin Number: 13)
5V (Power source; 5V - Pin Number: 14)

Given that structuring of the nodes' naming implies these pins might be variously configured as digital input/output, analog input, SPI (Serial Peripheral Interface), and I2C (Inter-Integrated Circuit) data and clock pins.

Based on this information, this project seems to be in the preliminary stages, with no circuits connected to the board yet. Should you plan to design connections, consider refering to these pin designator names for specificity.

lvangelis

can you add the LDC1312 component with the SD pin on pin number 2 and the Interrupt on pin number 1?

copilot

For adding the LDC1312 Inductive Touch Sensor to the project, you would first add the component to your design and set up the part properties accordingly.

After that, you would need to connect it to the XIAO nRF52840 Sense board. Unfortunately, the current pinout of the XIAO nRF52840 Sense board does not clearly define an interrupt or SD pin. However, if we treat digital pins as general-purpose, the pins can likely be assigned as per your need.

You can try the following steps:

Connect the SD (Shutdown Pin) of the LDC1312 to the P0.03_A1_D1 (Pin number 2 of XIAO).
Connect the Interrupt pin of the LDC1312 to the P0.02_A0_D0 (Pin number 1 of XIAO).

For a precise and successful design, it's recommended to verify the pin configurations based on both LDC1312 and XIAO nRF52840 datasheets as well as your application requirements.

Note: Make sure that the voltage levels match between the components to prevent damage - you might need to use a level shifter if necessary.
