## Questions & Answers

**Q: should this kit have come with male connectors or are those ordered separately?**
A: The sensor shield board that sits on top of the UNO board has pins, so the female connections on the connection wires work fine.   My kit came with a strip of male-male connectors also, but I did not use them.

**Q: what batteries are needed?**
A: You need to use 3.7V 18650 batteries.

**Q: Is the r3 board is a arduino uno board? the board in the picture does not have any description on it.**
A: Yes,It is with arduino uno board.

**Q: How many batteries are needed? And what is the final voltage coming out of the battery box?**
A: I think this came with a 2-cell battery pack which fit the 3.7V 18500 Li-ion cells (7.4V total).  At first I switched it out for a 6 cell AA holder, but later got some 18500 cells and charger and really liked using them.  This is a nice project kit.  Enjoy.

### ⭐⭐⭐⭐ Needed for a school project and did not disappoint
*by C***E on May 2, 2025*

Came with everything listed and worked when assembled. Finding the specific car on their website was a little difficult but the wiring diagrams and provided code were sufficient. Needed this for a school project so can't beat the price for what you get. Quality was decent and got the job done. It need 18650 batteries which are not cheap at most places.
