Dear [Developer's Name or Development Team],

I hope this message finds you well. I am reaching out to provide some constructive feedback on the MCU identification guide provided in your documentation.

I found the current descriptor, "Your MCU looks like the below picture (the pins on the side of the board are shorter)," to be somewhat ambiguous, primarily because the board has multiple edges with pin-like components, which can lead to confusion.

Moreover, upon closer examination, it appears that the distinguishing feature is not the length of the pins but rather the quantity. A more accurate and helpful description might be, "The row of pins on the bottom edge, as pictured, has fewer pins."

This specificity would greatly aid in the correct identification of the MCU version and facilitate a smoother setup process for your users.

Thank you for considering this feedback, and for your continued efforts to improve user experience.

Warm regards,

[Your Name]
