Playing MP3 with Microbit

I just started learning about coding a few weeks ago. I tried some micro:bit projects. Now I want to make something like: When you are moving, it will play a mp3. I found this link and bought the materials. It includes a df player mini, a bread board, an expansion board, a speaker, some wires and a micro:bit. I think I placed the wires in the right place (diagram shown below), the df player mini should light up but it didn’t, now I am starting to worry if it is my wiring problem or the df player mini’s problem. Please tell me if I did something wrong, or the df player is broken.
