LILYGO T-Bao tiny AI robot combines ESP32 and Kendryte K210 RISC-V chip, features camera and display

The T-Bao AI robot is a compact embedded device/robot that combines an ESP32 and a K210 RISC-V microcontroller and can perform face recognition and robotics applications.

This compact device features a 1.54-inch 240×240 capacitive touch screen, a 2MP OV2640 camera, a MAX98357A I2S audio amplifier, a DRV8833 motor driver, an MPU6050 6-axis motion sensor, and an AXP202 PMU for power management.  Additionally, it supports USB charging, offers LEGO blocks compatibility, and can move around with integrated caster wheels. These features make it usable for educational projects, robotics, IoT applications, and embedded systems prototyping.

While writing the specifications, I noticed that a lot of information was missing as the company does not show what the internal components of this product look like. They also mention that there is a DRV8833 motor driver, raising the question: is it solely driving the caster wheels, or can it be used to drive other motors as well?

LILYGO T Bao is an AIOT development platform

The company also mentions that additional documentation, sample code, and other information can be found in their GitHub repo but after thoroughly checking the repository I cannot find anything specific about the T-Bao. The device has a USB-C port built into it but that port cannot be used for programming as the company mentions it as a charging port. To program the device, the little robot ships with a CH9102-based USB to high-speed serial chip which is used to program the ESP32 chip.
