Design Notes

For optimal RF performance, place the antenna on the edge of the PCB with a clear ground plane underneath. Use a 50-ohm impedance-controlled trace for the RF output. Keep the RF section isolated from digital circuitry to minimize interference. Follow the layout guidelines in the STM32WB55VE datasheet and application note AN5165.

Decouple the VDD pins with 100 nF ceramic capacitors placed as close as possible to each pin. Additionally, use a 4.7 uF bulk capacitor for the main supply. For battery-powered applications, consider using the low-power modes (Sleep, Stop, Standby) to reduce current consumption. The standby current is 1.62 uA, which is ideal for battery-operated devices.

Ensure that the 32 MHz crystal for the radio and the 32.768 kHz crystal for the RTC are properly connected with the correct load capacitors. Incorrect crystal selection can cause radio communication failures. Also, avoid placing high-speed digital traces near the RF section to prevent noise coupling. Refer to the STM32WB55VE datasheet for crystal specifications.
