Building an MCU Project
Thought for 55 sec
To get the LSM6DSRTR (U3) talking over I²C, you still need to tie its interface-select and I/O-supply pins. Here’s what I recommend:
Table
| Pin on U3 | Net | Purpose |
|---|---|---|
| VDD_IO (pin 5) | VDD | Powers the sensor’s I/O domain |
| CS (pin 12) | VDD | Disables SPI mode so I²C takes over |
| SDO/SA0 (pin 1) | GND | Selects the default I²C address (0x6A) |
(Optional) You may also want to pull up SDA if you haven’t yet.
Shall I apply these net connections now?
Please help me with SW4. When enabled it should power the rest of the circuit from BT1 battery. When disabled it should power off the device.

Here are the updated net connections to configure SW4 as the main power switch:
Table
| Net | Connections |
|---|---|
| BT1 - SW1 | SW4:3, BT1:POS |
| VDD_sw | SW4:2, U4:VDD, C1:1 |
Would you like to apply these changes?
