Hello everyone! Welcome back to my channel. I am Ayan Malik, and right now, you are watching Abhan Thoughts. I hope you all are doing well. Today, we are diving into the VC-02 Offline Voice Recognition Module, also known as the Offline Voice Assistant. This module offers a unique solution for controlling your home automation setup offline, without the need for WiFi.

Introduction to VC-02 Module

The VC-02 module is a compact, cost-effective offline speech recognition device developed by Sejan A. Thinka Technology Co Ltd. It uses a US1 6 P6 chip by Ye Sound, featuring a 32-bit RISC architecture core with a DSP instruction set specifically for signal processing and speech recognition. Notably, it supports 150 local commands and operates in both English and Chinese languages.

Technical Specifications

Size and Build:

• The module measures 18 * 17 * 3.2mm and resembles a NodeMCU series module.
• Inside is a 32-bit processor running at 240 MHz, supporting DSP instruction set and FPO floating point operations.
• Memory includes 242 KB high-speed RAM and 2MB API flash memory.

Audio I/O:

• Supports one analog microphone input and four digital microphone inputs.
• Dual-channel DAC output and I2S input/output support.

Power and Clock:

• Operates with a power input range of 3.6 to 5 volts, with a supply current of over 500 mA.
• Built-in 5V to 3.3V and 3.3V to 1.2V LDOs for power management.
• RC 12 MHz clock source and PLA locked loop clock source.
• Built-in power-on reset, low voltage detection, and watchdog timer.

GPIO and Interfaces:

• 10 GPIO pins for custom/home automation projects, supporting AI I2C, ADC, and PDA.
• Two methods for firmware upgrades: JTAG debugger program and serial feed program.

Setup and Usage

Installation Steps:

1. Download Necessary Files: Access the AI Thunker website and download the firmware, WS4 driver, and burn tool.
2. Extract Files: Unzip the downloaded files and organize them.
3. Install Serial Driver: Run the ch341 AR application and complete the installation.
4. Connect Module: Plug the VC-02 module into your PC.
5. Upload Firmware: Use the Hummingbird Update Tool to upload the firmware, ensuring you select the correct COM port and press the reset button on the module to start the update.

Commands and Control:
The module comes preloaded with various commands for controlling air conditioners, lights, and other appliances. Here are a few example commands you can use:

• "Hey pudding hi" to wake up the module.
• "Turn on the air conditioner," "Turn off the air conditioner," "Cold mode," "Warm light turn on," etc.
• Commands for adjusting temperature settings range from "16 centigrade" to "30 centigrade."

These commands provide a convenient way to manage multiple devices without Internet reliance.
