Due to logistics delays, the courier took a very long time to arrive. After unpacking, the packaging was still as good as before, and the C3 development board was also affixed with an anti-tampering sticker.

The small bag next to it contains the 2SMPP03 air pressure sensor, which is a very precise and fragile sensor. The principle is that four very thin varistors are installed on a very thin and elastic silicon wafer. When there is a pressure difference on both sides of the membrane and it deforms, it will pull the resistor to deform, causing a slight change in resistance. In principle, if you want to use it, you can't avoid the design of various op amp peripheral circuits, and it's time to get back to the headache of analog circuits.

After taking everything apart, you can see the entire sensor and the exquisite original Espressif development board.
