MEGA32U4 Acceleration Sensor Module
SKU: KIT0042
Nova uses MEGA32U4 as its main processing unit, resembling Arduino Leonardo but more portable. Its small size suits toys, installation art, VR, and game peripherals. It uses a 3.7V lithium battery (free supply) and Micro USB for charging. As an acceleration sensor module, it offers vibration measurement, with sample codes for LED control and issue solutions available.

The ports can be clearly distinguished as the picture performanced. And once you have gotten a Nova, you can easily know which port is D13 and which one is A0, etc.
