Custom Raspberry Pi Carrier Board 'SaraKit' Powers LEGO RC Car
The car is smartphone operated and stands out with 4-wheel drive alongside two differentials lending to some serious precision driving. The SaraKIT board makes it easier to control these extra components with features like fractional angle control. Of course, the body is made using LEGO for fun but you can also make adjustments to the build by changing the gears at the rear to impact both power and speed.
