Notes de conception
For optimal radio performance, match the antenna impedance to 50 ohms and place it away from the MCU and other components. Use a ground plane under the antenna and ensure proper decoupling of the RF supply pins. Refer to the STM32WBA5xxx application notes for antenna design guidelines.
Decouple all supply pins with 100 nF capacitors placed as close as possible to the pins. Add a 4.7 uF bulk capacitor on the main supply. For battery-powered designs, use the low-power modes (Sleep, Stop, Standby) to extend battery life. Ensure the supply voltage stays within 1.71V to 3.6V.
Use a 32 MHz crystal for the radio and a 32.768 kHz crystal for low-power timing. Place the crystals close to the MCU and keep traces short. Ensure a clean ground plane and avoid routing high-speed signals near the crystal. Follow the layout guidelines in the STM32WBA5xxx datasheet.
