Verifying 3V3 decoupling capacitor connections...

Started: 4.1. run decoupling_caps review and message the user confirming that C8, C9, C10, and C11 remain connected to the 3V3 net and are positioned near U3.

Here’s the summary:
Work done
- DWM1001 (U3) added and powered: VIN → 3V3, GND → GND
- UART & reset nets:
- U3 UART_TX → U1 D7 (D7_RX_GPIO44)
- U3 UART_RX → U1 D6 (GPIO43_TX_D6)
- U3 NRST → U1 D1 (TOUCH2_GPIO2_A1_D1)
- Battery path:
Unable to do
- I can’t automatically verify capacitor placement near U3; please confirm that C8–C11 remain on 3V3 and are positioned adjacent to U3.
Success criteria
- ✅ U3 is present and powered
- ✅ UART & reset are correctly wired
- ✅ Battery positive flows via SW1; 5V net is disconnected
- ℹ️ 3V3 decoupling caps retention: manual confirmation needed
Next, would you like to review the PCB layout orPosition the decoupling caps around U3?
