This week I decided to look into the PCB Schematic and look more into the motion sensor trying to find vendors that sell them. Originally I wanted to have the PCB schematic and layout done but I first need to find a vendor for the motion sensor we want before I can finish doing this. I am currently speaking with a vendor to arrange a part order for a particular motion sensor. So instead of sitting around waiting for that I decided to also test the IMU functionality to see if it would be possible to implement our entire pen’s motion just with the IMU. After testing, the IMU did not work that well at detecting position as we would have hoped so we are thinking of sticking to our original design of using an optical motion sensor. Here is some photos of the IMU temporarily being setup and tested using an STM32 board until we get our XIAO MCU:

My progress is a little behind since I was hoping to have the PCB stuff done and ready to order by the end of this week. The actions I plan on taking to catch up is continue talking to the vendor I am hoping to buy from and get the datasheet from them so that way I can start building the schematic and laying everything out by the next status report. By next week, I hope to finally have the motion sensor decided and ready to order. In addition, I am hoping to have the PCB schematic and layout for the motion sensor completed as well.
