Also 2 of those photos are from a prototype. The final version, which you'll receive, has the buttons at the edge of the PCB.
This is a kit to help you practice soldering before undertaking a more expensive pedal build. You can solder 10 resistors in the practice area, plus save the leads you trim off and solder those too! When you have a bit more confidence, add the buttons, 3 more resistors, and 3 LEDs to make a fun flashlight project.
This kit includes
PCB (printed circuit board) with a practice area, and a flashlight project area
(3) momentary buttons
Battery holder (CR2025 or CR2032) - battery not included
