6. Typical Application Circuit
7. LAYOUT Notes
1). when placing modules: antenna below (including PCB back) and around can not have any traces and devices,the antenna should be placed in the open without shelter place in order to ensure�the best performance�of antenna.
2). To ensure the integrity of the ground, we recommend a large area paved, multi-punched. Since Bluetooth to work in the high-frequency band, poor grounding will bring the current sound.All the network with the main power supply ground wire as a reference point, please.
