9 IN 1 Multi-function Expension Board

Characteristics:
• Fully compatible with UNO R3 interfaces
• Offering experimental base module for Ard beginners
• A board integrates various module functions
• No welding, no connection, you can directly download the program to complete the experiment
• Provide all module code library files, all tested and ready to use
• Set aside the expansion port, you can complete the experiment with other modules
• The high ripening pin design prevents contact with the USB port of the UNO board, so avoid short circuits
