@help how do I place ground symbols on P1 of C1, C2, and C3?

flux

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.
  1. 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.
  2. 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?
  1. Power Supply:
    • This section typically includes the power input, protection circuit, and voltage regulation to ensure the device gets the right voltage and current.
  2. 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!
