Note:The following items are not included in this kit and must be provided by you.

1). Microbit V2 (you need to buy them yourself)

2). Three AAA Batteries (you need to buy them yourself)

## Parameters

**Note:** the two colored headlights, two photosensitive sensors, the IR receiver and two motors are already integrated in the car baseplate.

Connector port input: DC 4.5V

Operating voltage of sensors: 3V

Motor speed: 200RPM

Working temperature range: 0-50℃

Dimension:`99*78*58` mm

Environmental protection attributes: ROHS

The motor speed can be adjusted via the PWM

Due to the small number of IO ports of micro:bit, the micro:bit board sends control instructions to STC8G1K08 via the IIC, and then ST8G1K08 sends PWM to control HR8833 motor to drive IC, thus controlling the motor to rotate. LED RGB is controlled in the same way as above.
