Stem Micro bit Robot Kit Supplier

This is an entry-level tracked robot designed specifically for the micro:bit V2. It uses graphical programming software with a drag-and-drop block interface, allowing you to easily control and build your smart robot.

I have chosen the micro:bit V2 as the main control board, and it is paired with various functional modules that enable features such as line following, obstacle avoidance, ultrasonic distance measurement, servo control, and Bluetooth remote control.

micro:bit V2 Interface Overview

• MP2636: Power management chip for charging and boost discharge.

• 8205S: Dual N-channel MOSFET used for circuit protection.

• DW01: Lithium battery charging and discharge protection chip. Provides overcharge, overdischarge, excessive current, and short-circuit protection.

• RT9193-33: 3.3V voltage regulator chip, used to supply power to the micro:bit V2.

• MLT-8530: Buzzer.

• PCA9685: I2C interface PWM control chip, used for expanding I/O ports.

• TB6612FNG: Dual H-bridge motor driver chip.

• TLC1543: 10-bit ADC (analog-to-digital converter) chip, allowing easy integration with analog line-following sensors for the micro:bit V2.

• APA102: Dual-wire control full-color RGB LED light.

• 18650 Battery Holder: For housing the 18650 lithium battery.

• Power Switch: To turn the system on/off.

• Micro USB Power Port: For powering the device.

• Lithium Battery Charging Port: For charging the battery.

Indicators of the robot kit:

• WARNING: Lithium battery reverse connection warning indicator.

• CHG: Charging mode indicator.

• BOOT: Boost mode indicator.

• PWR: Power indicator.

Peripheral Interfaces (on the back):

• Convenient connection points for servos, ultrasonic sensors, and line-following sensors.

Motor Interfaces (on the back):

• Connection points for motor drivers.
