Have you considered MXC4005XC for gyro sensor ?

[happytm]

I am following your research and efforts to build $1 TinyML device. I myself is designing a BLE beacon based on CH582F micro controller with analog temperature, light and I2C gyro sensors for around $1 in Tomu/Fomu/Bomu (neck pendant for elderly patient) format. As my pcb is 12x14 mm I was looking for smallest parts to fit on limited space on pcb and came across following part. I will be watching your progress specially for Microphone part which I would like to include in my design.

Have you considered MXC4005XC for gyro sensor ? It is very small size at reasonable price.

Hi @happytm and thank you for the comment. Apologies for the lack of response - it seems I do not get notifications on issues in this repository! The MXC4005XC looks like a very relevant part, it looks quite competitive in terms of price and features with LIS2DH12, which I currently have as part of the BOM.

How is it going with your project? I also recently ordered some CH582F development boards, as I see this chip can also be very attractive for these kinds of use cases.
