Hello, 

I am having an issue where the servo motor connected to the mouth pin of the voice module only works half of the time. I have to constantly power cycle everything to get it to work.  The motor is powered by external power with all the ground connections shared. I've tested and confirmed the servo is good. Has anyone had any similair issues with this voice module?

The way that I got it to work consistently when using the I2C bus is to lower the speed to 100k HZ from the 400k Hz that is the default.

BTW - do you think it's weird that this manufacturer doesn't provide the specific datasheet describing the address space of the device and parameters on their own website? Shouldn't there be a major category at the top of this forum for either “Downloads” or “Support” that would point us to the datasheets?

But if YOU have access to that datasheet describing the address parameters - please let me know.

Also if you know how to extend the “WAIT” time, I would like to know that as well.

Hi,

I'm currently having the same issue with my two servo motors and voice module. I've got this running on an RP2040 pcb and micropython. Everything works really well up until the voice module kicks out. Maybe its something code related? It seems like we both have hardware that works well, although I did notice the RP2040 printing out an error code in the shell: Read issue: [Errno 110] ETIMEDOUT.
