General Troubleshooting Tips

So, you finished building your DIYRE kit and it's not working. Here's our recommended troubleshooting procedure:

  1. Don't panic! In all likelihood the issue is something small and simple to fix.
  2. Retrace your footsteps. Go back through the assembly guide, checking each step as you go. Don't assume you got something right—confirm it visually as if you were doing a pre-flight checklist.
  3. Check for common errors.
    1. Are all resistors in the correct positions? Check the color bands of every resistor against the sorting sheet. Pay especially close attention to those that start with the same number, for example 4.7k and 47k.
    2. Are all ICs in the correct position and orientation?
    3. Are all capacitors in the correction positions and orientation?
    4. Are all diodes in the correction orientation?
  4. Check your soldering. Joints should have a smooth, shiny, concave surface, and cover the entire pad. Check out this article for photos of good and bad solder joints: Adafruit Guide to Excellent Soldering. If any of your joints look less than perfect, follow this process to fix them: Cleaning Up Solder Joints
  5. Clean your board. Sometimes small pieces of solder or flux can get stuck to the PCB and cause issues. Go through methodically and remove any flecks on the top and bottom of the board—a little pressure from the tip of screwdriver is all it takes.
