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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Decent *by R***1 on December 22, 2020* Good fit the most part but some of the instructions are hard to follow. Good fit a project but helps if you have done something like this before. ### ⭐⭐⭐⭐⭐ More Robot than car, good fun for all ages *by H***A on August 22, 2020* The pictures are a perfect reflection of the parts received. Also the after sales support of the supplier was prompt and efficient. This being my first build, the instructions were sufficiently comprehensive to get started. Only negative is that the non-standard batteries are not included. ### ⭐⭐⭐⭐ 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. ## Frequently Bought Together - LAFVIN Smart Robot Car 2WD Chassis Kit with Ultrasonic Module R3 Board,Remote Compatible with Arduino IDE DIY Kit - Miuzei Electronics Component Fun Kit with Supply Module, Jumper Wire, 830 Tie-Points Breadboard, Precision Potentiometer, Resistor, LED, Compatible with Arduino, Raspberry Pi, STM32 - STM32 Nucleo-64 Development Board with STM32L476RG MCU NUCLEO-L476RG --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/162683991-lafvin-2wd-smart-robot-car-kit-with-r3-board-ultrasonic](https://www.desertcart.vu/products/162683991-lafvin-2wd-smart-robot-car-kit-with-r3-board-ultrasonic) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-05*
