Solid performance, minor setup curve
The hardware quality is excellent. It took a little time to configure the GPIO mappings correctly, but once done, it runs stable 24/7. Good value for money.

Good learning tool
Easy to integrate with Arduino and ESP32. The documentation could be slightly more detailed in English, but the community support fills the gaps. Solid hardware.

Reliable for control systems
We used this for a factory control panel prototype. The latency is low and it handles specific command sets very well. Highly recommended for industrial evaluation.

Exceeded expectations
I was skeptical about offline voice control, but the ASRPRO core is surprisingly robust. Setting up custom wake words was straightforward using their toolchain.
Q: Does this module require Wi-Fi to function?
A: No, the ASRPRO 2.0 performs all voice recognition locally on the chip. It is designed specifically for offline operation and does not need an internet connection.
Q: What is the operating temperature range?
A: The module operates reliably between -20°C and +70°C, making it suitable for most indoor industrial and consumer electronics applications.
Q: Is there an English SDK available?
A: Yes, we provide an English version of the configuration software and API documentation. You can download it from the resources section on our official website.
Q: What microphone type is compatible with this board?
A: The board supports both analog microphones and digital PDM microphones. Please refer to the pinout diagram in the datasheet to select the correct input mode via jumpers.
Q: Can I train it to recognize my own custom phrases?
A: Yes, you can customize up to 150 command phrases using the official configuration tool provided by Tianwen. You simply define the trigger words and corresponding output signals.
