Notes de conception
For optimal RF performance, place the 2.4 GHz antenna on the edge of the PCB with a 50-ohm impedance-controlled trace. Keep the antenna away from ground planes and other components. Use a ground plane on the layer below the antenna for proper radiation. Follow ST's application note AN5129 for detailed antenna design guidelines.
Decouple the VDD pins with a 100 nF ceramic capacitor placed as close as possible to each pin, and a 4.7 µF bulk capacitor for the main supply. For the VDDA pin, use a 1 µF capacitor and a ferrite bead to isolate analog noise. Ensure the supply voltage stays within 1.71V-3.6V, including during BLE transmission current spikes.
Place the 32 MHz crystal and its load capacitors close to the PH0/PH1 pins, with short traces to minimize parasitic capacitance. Similarly, place the 32.768 kHz crystal near PC14/PC15. Keep these traces away from high-speed digital signals to avoid interference. Use ground vias around the crystal area to shield it.
