C1, C2, C3

Using Schematic Tool.

No. The goal has not been completed.

C1, C2, and C3 have P2 tied together on “Net 1”.
Their P1 pins are still unconnected and not on the GND net.

Would you like me to create a plan to add GND symbols and wire P1 of C1–C3 to GND?

Reading docs for: "How do I place Ground symbols/portals in the schematic and connect multiple pins (e.g., C1:P1, C2:P1, C3:P1) to the GND net quickly? Step-by-step instructions and any quicker methods like net portals, multi-select wiring, or assigning a net name."

This is the most relevant entry I found related to your request:

“1. From the parts library on the left, drag in a portal with a ground symbol to your schematic as a secondary ground. (Search for it in the library!) 1. Ground portals behave identically to normal portals (discussed below) and differ solely in their visual appearance as a symbol in the schematic.

Once you’ve connected your ground portal component, connect the secondary ground to the primary through your desired filter/bypass capacitor or any other filter network, as necessary.
Ensure that all ground portals share the same name so they will then share the same secondary ground net in the PCB editor.”

Of course! You're in the process of designing an environmental sensing node using a Nordic nRF52840-QIAA-R microcontroller with Bluetooth 5.0 capabilities. Let's focus on a basic block of the circuit. How about we start with a simple section like the power supply or the IMU connection?

Power Supply:
- This section typically includes the power input, protection circuit, and voltage regulation to ensure the device gets the right voltage and current.
IMU Connection:
- This involves connecting the LSM6DSO32TR IMU sensor to the microcontroller over SPI and handling its power requirements.

Let me know which section you'd like to start with, or if you have another particular part of the circuit in mind!
