Splicing
Let's splice LEGO.
For the steering system, we first used the SG90 servo. We can see that worked very nice, use hot melt glue to fix SG90 to the steering wheel.
Spliced into the power part, you can see that this Porsche uses a 6-cylinder horizontally opposed engine, for toys, the power transmission loss of the horizontally opposed engine will be relatively large, so we used a 12V high speed motor to drive like this:
About the microcontroller, ESP is our first choice, because ESP-NOW, it's a wireless communication protocol for quick responses and low-power control.

M5Stack Roller485 Lite Unit without Slip Ring (STM32) You can find detailed upgrade information in this article: Roller485 Unit, New Robot Motor by M5Stack
This is a high performance robot joint motor.
Let's put it in our Porsche. That makes me very excited. The roller485 unit is perfect for this car.
Have fun!
