KitiBot tracked robot building kit for micro:bit

When KitiBot meets micro:bit, when kids meet programming, the mysterious robotics becomes simple, each interesting idea will come true. By using the graphical programming software, learning programming, and exploring robotics would be as easy as building blocks.

This KitiBot tracked robot kit uses the BBC micro:bit (NOT included) as the host controller, combined with several functional modules, it is easy for the kids to experience robotic tricks such as: line tracking, obstacle avoiding, ultrasonic ranging, servo operation, Bluetooth remote control, etc.

The KitiBot for micro:bit

• Onboard connector for plugging in micro:bit
• Integrates MP2636 Li-ion battery charger with system boost, allows charge the battery even when using
• Integrates DW01+8205S Li-ion battery protection circuitry: reverse protection, over charge/discharge protection, over
  current protection, and short circuit protection
• Integrates TB6612FNG dual H bridge motor driver, high efficiency, low heating
• Integrates PCA9685 PWM controller, micro:bit IO expansion
• Integrates TLC1543 AD acquisition chip, allows connect multi analog sensors to the micro:bit
• Integrates 4x APA102 colorful LEDs, dual-line control, no more conflict between the WS2812B RGB LED and Bluetooth
• Onboard buzzer to play music
