These parts you may either already have, depend on where you're located for a good deal, depend on personal preference, or are optional. As a result they are not accounted for in the total price.

**Note**: Make sure to go through the list below to make sure you have everything you need.

### A gamepad or remote controller

This is technically not a requirement, especially if you're planning on making the rover autonomous, but is highly recommended. Any USB based option should work here.

We recommend getting spools of 18AWG (red and black), 20AWG (white, red, black) and 22AWG wire (4 colors). The wire has to be stranded and not solid core as it will bend during operation. For each wire type, if possible, get ribbon cable where each wire is attached to another one which will help with keeping wiring clean and manageable.

Links for the wire can be found below on Amazon:

- [18AWG](https://www.amazon.com/Silicone-Electrical-Conductor-Parallel-Flexible/dp/B07FMRDP87/)

- [20AWG](https://www.amazon.com/Gauge-Electrical-Wire-Conductor-Cable/dp/B0B3MGD254)

- [22AWG](https://www.amazon.com/22AWG-UL2464-Power-Yellow-Conductors/dp/B07TLB9VYX/)


To protect the cables from chafing against the sharp aluminum parts, we recommend [cable sleeves](https://www.amazon.com/Best-Sellers-Cable-Sleeves/zgbs/electronics/6577542011).
You can also use [grommets](https://www.gobilda.com/plastic-grommet-14-1-12-pack/), filing down the sharp edges or burs, applying tape to the edges, or using expandable wire sleeving.

Heat shrink is a must have for keeping cables nice and snug.

Take a look at the [wiring overview](../electrical/wiring/README.md#overview) to get an idea of what you will be building. You'll need crimps and connectors for DuPont, Bullet, XT30, and JST styles. Crimping doesn't have a 100% success rate, so we recommend getting extras or buying a kit if you're planning on using them for other projects as well. Here are some options for each set you need:

* A RPi ribbon cable, e.g. from [Adafruit](https://www.adafruit.com/product/1988) but available in many places. While you could use header pins for this connection, the cable is the cleanest solution
* Drive Motor Connectors, from [Amazon](https://www.amazon.com/Amangny-Extension-Power-Express-Adapter/dp/B09NBRQ9CC)

* DC power meter: [Amazon](https://www.amazon.com/gp/product/B017FSED9I/). This LCD display reads out current, voltage, power, and energy, and can be put on the back where the rectangular hole is in the laser cut cover.

* batteries: many options available here. We recommend getting LiPo batteries. You'll need a battery that can provide over 12V, so a 4s battery works well. You can get batteries with various mAh ratings (how many milliAmperes the battery can output for 1 hour). We recommend any option over 4000mAh. Higher capacity comes at a higher cost. You can also get more than one battery and swap them out. The rover can carry them as well.

* You'll also need a charger for the battery. Make sure it can support the battery you bought. For the Zeee options, [this model from Amazon](https://www.amazon.com/Hobby-Fans-Professional-Balance-Discharger/dp/B09XC91BWJ/ref=sr_1_6?keywords=LiPo+charger&qid=1690484744&sr=8-6) will work.
