Here is a photo of the inside view of the watch. The Pro trinket is located on the upper end, and the power boost is on the lower end. Due to the fact that my watch is not made using a custom circuit board and utilizes only "Off the shelf components" there is not much room for expansion. I hope to install my TMP36 temperature sensor in the near future and make some software changes. Sorry for the inactivity, stay tuned for more updates in the upcoming weeks
