SD Card Shield Arduino

This Module is a Rotary Incremental Encoder. It encodes the shaft rotation signal and outputs the signal by electronic pulse. The Grove –Encoder is a module of the Grove series and has a standard Grove interface. When you need to add a knob to your project, for example a volume knob for a speaker, a selection panel or a digital input, this should be your first choice.

The Vma210 Expansion Board is designed to allow easy access to the interface pins of an Arduino Nano. Each DIO pin or analog pin on the Nano is brought to an appropriate header.

This 4-digit 7-segment shield has 5 buttons that can be used as menu selection buttons or control buttons, using I2C to conduct the digital call.

This RS232 shield is designed for the Arduino controller and can easily convert UART to RS232 interface.
