This electrical circuit is very small, more exactly the physical size of board is 80x35mm.
However, it has enough function.
It can manage:
- Throttle control
- Brake detection
- Emergency detection
- Radio On/Off switch
- On/Off switch of vehicle
It can show some imformations for the driver:
- speed of car
- lap time
- elapsed time
This circuit includes:
- ARM 32-bit Cortex-M4 CPU with FPU
- A display module, number of digits: 8
- a CAN interface (500 kbit/sec)
- a switching power supply (5V0) and a LDO (3V3)
In the car we don't have enough space, so, we had to design a steering wheel.
Nowadays the 3D printing is very popular. Therefore we also used this technology.
