This weekly report summarizes the progress of the Happy361° engineering team. It discusses learning about sound modules and SD cards. Circuit diagrams show an SD card circuit that can be used with a module powered by either USB or 3.3V SD card. The strong point is its finished, quick-use module with an SD card. The weak point is lacking an SD card socket and audio amplifier circuit. Next week's task is to learn about audio amplifier circuits.

Weekly Progress
For my part about sound , I need to learn about sound. So this week I learn module MP3
and SD card
This is the SD card circuit for using with
This finished module can use with USB
or SD card. module(in the left)
For SD card , it need 3.3 volt supply
and USB need 5 volt supply
Engineering Analysis
Strong Point
- It’s a finished module which can use quickly by put SD card in it.
Weak Point
- It doesn’t have socket for SD card and the audio amplifier circuit
Next Week Job
I will learn about audio amplifier circuit.
