Overview

T-Bao is an open-source AIoT terminal based on ESP32-D0WDQ6-V3 and K210 RISC-V AI chip, featuring high performance, low power consumption, expandability, and programmability. It deeply integrates the K210 RISC-V architecture AI chip (with KPU neural network processor) with the ESP32 dual-core Wi-Fi/BLE communication module, equipped with a professional OV2640 2-megapixel camera (supporting 180° rotation) and ST7789V 1.54-inch IPS touch screen (240 × 240, 90° adaptive rotation). Supports millisecond-level face recognition and dynamic image processing.

Built-in MAX98357A I2S digital power amplifier, MSM261S high-sensitivity microphone array, and AXP202 intelligent power management. Integrates MPU6050 six-axis sensor, TF card storage, and rich interface resources (UART/SPI/I2C/Touch). Compatible with Arduino/MicroPython ecosystem. Suitable for industrial vision detection, smart security, AIoT terminals, and educational robots.

Quick Start

Example Support

Example	PlatformIO/Arduino	ESP-IDF	Description
LilyGo-K210-Script	✓		Direction recognition, face recognition, speech recognition

K210 Firmware Flashing

1. Download the latest MaixPy firmware: MaixPy Firmware
2. Download flashing tool: kflash_gui
3. Select the corresponding firmware and model files for flashing

Note: Speech recognition requires writing the model file maix_asr_2900k_0x500000.kmodel to address 0x500000 first, then flashing the firmware.
