Soldering Instructions{ .md-button .md-button--primary }
The challenge is to solder all the components on the PCB in the shortest time possible.
- Level 1 - THT components
- Level 2 - SMD 1206 components
- Level 3 - SMD 0603 components
If you manage to plug in all the components correctly, the LED will flash at about 2 Hz when plugged into the USB port.
