This shield needs fewer pins than our v1 shield

On-board micro-SD memory card adaptor for storing of audio

Also included with the Notecarrier Function Board

Input 1 is always an input only pin and has a 47k pull-up resistor (not 4

12V Solenoid Valve - DN15 Light/Imaging Sensors but there's actually an integratedThis is a 12V normally closed solenoid valve with no polarity distinction. It is normally closed until powered on. You can implement real time water flow control with our water flow sensor . It can be widely used in automatic agriculture, fisheries and other projects that require water flow control. The direction of value terminals can be adjusted according to demand. The unit has stable performance, reliable quality, high sensitivity and other
