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.
If you have not done so already, remember to remove the Propeller chip, and LM386 chip before you do any soldering. We don't want to overheat them or damage them. Protect your ICs! |
