Yahboom Voice Recognition Playback Module Sound Sensor 85 Offline Voice Commands for DIY Robot Expanding Board Compatible with Arduino Raspberry Pi

This voice command board works really well for the price. Comes with dual microphones and a speaker.Interface is via UART / UART over USB and should be usable from any robot with a serial port. The mounting hardware included is a little odd. The standoffs are very long, as are the screws. And rubber grommets are included. I opted to use shorter stand-offs and screw but still used the included rubber grommets to reduce vibration. It all works perfectly.I have a deep voice. Command recognition for me is around 90% in low noise and drops to around 75% in higher noise environments. It works better than other similar products i have tried.For $35 I am super-impressed with this board.

After hours of wasting time on this crap I have determined it has no communication from its RX/TX pins. It will communicate via serial but not through the UART. That's what I needed. This is obviously yet another product clearly intended for raspberry and esp32 that they lazily "ported" to Arduino with the absolute bare minimum effort. I don't want another one. I just want my money back. And my time but that's impossible. Oh and the hopes and dreams but again, crushed beyond repair by BAD BUSINESS.
