keyestudio Multi-purpose Shield V2
Introduction
Multi-purpose Shield V2 is a learning board based on Arduino. No need for soldering and connection. Download directly the program to complete experiment. It is multi-purpose and we offer code libraries of all modules that have been tested. You can use them directly. There are extended ports on the shield to help you to complete other experiment.
Specification
- Compatible with main controller on the market,such as UNO R3 and MEGA2560
- Using 6-channel LED indicator to show the working condition of program for modulating program conveniently
- Switching functions with 3-channel keyswitch
- One reset button
- Using revolving potentiometer to do analog input
- Alarming and making sound by passive buzzer module
- Using 4 bit LED Segment Displays to display data
Connection Diagram
Upload program to keyestudio UNO R3 BOARD, and plug this shield into UNO R3 BOARD.
