The speaker should be 4Ω 3W. The test in the video uses 4Ω 0.5 watt. If the power is too small, the sound will be small and the sound quality will deteriorate. (I don’t have 4 ohm 3W speakers here) You can plug and play by adding a case. Two-channel output with electret microphone.
If you do not use the exported BOM, the device parameters shall be based on the schematic diagram. https://www.bilibili.com/video/BV1qB4y1k7qD/?vd_source=f2ecf6d07c56387a85d94b53386 93a63
