T-Bao is based on the T-WATCH K210 host. The 13pin FPC reserved from the back extends the motor drive module. By using the reserved shaft design of the host, a PC+ABS shell is designed and manufactured. The power supply reserves a 9V battery connector. The base is designed with a 9V battery compartment (a large capacity rechargeable 9V battery is recommended), which is convenient for adding batteries. AIOT smart car can be programmed with T-WATCH K210 host and K210+ESP32+DRV8833 motor drive module to meet various AIOT creative applications.

The T-BAO ESP32 version is based on the T-WATCH host by replacing the bottom function shield and adding a car battery base, making it a smart car with a mini and cute appearance. On the basis of the ESP32 main control chip included in the T-WATCH host, the 1.54 capacitive touch screen + three-axis motion sensor + RTC clock + PMU power management chip is added a shield for the expandable car base.
The functions of the shield are: 3 RGB colorful lights, buzzer, and servo expansion port.
A 9V battery compartment is designed on the trolley shield, which requires the use of a high-capacity 9V rechargeable battery to ensure the endurance of the trolley. At the same time, there are compatible Lego blocks around the base.
You can build some interesting Lego blocks on the trolley to increase the fun of use. The software currently supports Pictoblox, KBIDE, Arduino, and micropython.
