Product Introduction

LU-ASR01 is a low-cost, low-power, small size, high-performance offline speech recognition module. It is easy to operate and fast to use. It allows users to quickly learn how to develop and use it in 3 minutes. The module has a very high degree of integration, integrates speech recognition, speech reply, IO control (multiple signal output) serial port output, temperature and humidity broadcast and other functions, and has one click download function, wireless Downloader Only one USB cable with type-C interface is needed to realize one click download, which is convenient for customers to change entries frequently for testing

1. 10 meter long distance wake-up.

2. 98% high recognition rate.

3. Customize 5 wake-up words and 200 recognition words.

4. One button burning function, no need for any Downloader, one USB direct burning.

5. With 3W power amplifier and external 4Ω /3W speaker.

6. Circular configuration, no programming, directly modify the entry and then burn it.

7. 8 IO ports, which can output PWM, high and low level, pulse signals, and steering gear signal without programming.

8. It can output one channel of serial port, optional hexadecimal and character data, and the baud rate is 1200-115200.

9. It can be connected with one DH11 or DS18B20 sensor to broadcast temperature and humidity.

Product Parameters
