You will be installing small 15Ω resistors into R4-R15. These are damping resistors. The LCD screen has to update very fast, so the microcontroller has to send a lot of data very fast. This can create interference on the line, so these small value resistors are put on each data line to reduce that noise.
Tools Needed
- Soldering iron
- Cutter
Parts Needed
- 12 x Small 15Ω resistors
Instructions
- Cut the resistors free, being careful not to bend the leads much.
- You've already noticed that these resistors are smaller than the others.
They work the same way; the LameStation uses smaller ones here to pack more of them into a tight space. Nifty, huh? - Install all the resistors into the footprints for R4-R15.
- Once they're all in, hold them all down with one of your fingers, and use a flat edge tool to bend all of the leads at once, and save yourself lots of time.
- Now have fun soldering all of these pads.
- Then trim all the leads.
- If you got them all straight, then good job, my friend. As you can see, I usually have a few that didn't go on quite right. No harm done; it will work just the same.
