And we finally reach the much awaited Apple S2 SiP—complete with the dreaded resin enclosure.

On the top of the SiP, tucked into the upper left corner, we spot a tiny pair of components:

Bosch Sensortec BMP280 Barometric Pressure Sensor

Likely an iteration of STMicroelectronics C451 gyroscope + accelerometer found in the original Apple Watch

But wait, isn't that the back? Where all the cables go? Turns out Apple decided to flip the SiP, so all of the connectors are on the same side as the things they connect to. Imagine that!
