Pomodoro Timer Solder Kit – Board Not Working

Hi everyone,

I recently assembled the Pomodoro Timer Solder Kit, but I can’t get it to work.

When I power the board, nothing happens—there are no LEDs or any other signs of operation.

However, when I connect the board to my computer via USB, it is detected as RPI-RP2, so the microcontroller appears to be recognized.

Has anyone experienced a similar issue or has any suggestions on what I should check next? If needed, I can provide photos of the assembled PCB.
