TabbyBot Quick Start

Introduction:

TabbyBot is a STEM robot car designed for Microbit programming. It utilizes a 18650 lithium battery, which provides sufficient power to drive power-hungry modules such as the AI camera module or voice recognition module, eliminating the need for multiple dry batteries. It comes with a built-in charging and discharging circuit, making it convenient to use.

TabbyBot features programmable resources such as LED, RGB, line-following sensor, infrared receiver sensor, ultrasonic sensor, servo motor driver, and motor driver. It also provides 4 programming interfaces for expanding additional sensors.

The board is equipped with LEGO-compatible mounting holes for attaching LEGO structural components.

Charging Guidelines:

You can charge it using a computer's USB port or a mobile phone charger. The charging voltage should be 5V, and the charging current should be equal to or greater than 1A.
To charge TabbyBot, connect a MicroUSB cable to the MicroUSB port on TabbyBot. A blue light will indicate charging, and it will turn green when fully charged.
It is advised to turn off the car's power switch while charging. Charging time is around 1.5 to 2 hours. Avoid prolonged charging to prevent accidents.

Usage Guidelines:

Remember to turn on the power when using TabbyBot to ensure accurate sensor readings.
The USB port on TabbyBot is only for charging and program downloading.
Pay attention to the polarity markings when installing the 18650 battery.
Avoid prolonged motor stalling to prevent motor damage.
