[UPDATE]

Added:

  • Box of motherboard header connectors. These have the same standard 2,54mm spacing and from what I tested, they make great contact with standard socket header pins. (buying more for future projects)
  • Red and black 12 gauge wires. These are for connecting the batteries because according to this website the 22 gauge wires aren’t rated for enough amps for power delivery. 22 gauge wires will be used for logic circuits however.

[UPDATE](mostly visual)

Added:

  • 3rd collumn to track the status of each parts. They will have one of 3 values:
    – (blank) for not yet ordered
    – “Ordered” for when it has been ordered and I have received confirmation it was shipped
    – “Arrived” for when I have received the part(s)

Removed:

  • Description above the table, it was no longer needed because I removed the previous place where a very brief list of parts was held

[UPDATE]

Added:

  • Specified the budget I have for this project as it may be useful on deciding on new features or justify part choices.

Modified:

  • Using Teensy 3.2 instead of LC. costs a bit more but it has 4 times more flash memory and some other features. I don’t want to be slowed down by hardware limitations, I want all space advailable to create a very precise and responsive firmware for this project. The higher clock speed and overclockability is also a nice feature, so I will be able to say that I overclocked my rc car even tho my computer isn’t.
