Assembly was smooth except for the “release tension on front steering wheels”. Also, not that the battery holder supplied works best with “button” type batteries, not the “flat” type – although the “flat” type does work. And, be aware the photos make the wiring seem “neater” than in real life – in one case, by leaving off a required cable completely in the photo. Finally, note this uses a USB camera, and that cable is “hard-wired” into the camera body.
Android application does work on older Samsung S4, does not work on S8. The server and client applications just work.
This version has separate boards – a step-down DC-DC converter module and a L298N DC motor driver and a PCA9685 16 Channel Servo driver. Each are available individually.
Note: an”alternative” Sunfounder “Smart Video” car – https://smile.amazon.com/SunFounder-Raspberry-Programming-Ultrasonic-Following/dp/B07R4ZFXT8/ a newer version. Instead of the L298N and step-down DC board, it uses a “Robot HATS” and a TB6612 Motor driver. The lack of a link for “Robot HATS” is not a mistake – it cannot be found for individual sale. So, if you have build-something-by-yourself plans, this is not a good kit to use.
