—-The RX and TX LEDs on the board will flash when data is being transmitted via the USB-to-serial chip and USB connection to the computer.
—-The UNO R3 puts SDA and SCL pins beside the AREF. Besides, there are two new pins placed near the RESET pin. One is the IOREF that allows the shields to adapt to the voltage provided from the board and the other one is reserved for future purposes.The UNO R3 works with all existing shields and can adapt to new shields which use these additional pins.

We have the manufacture factory,
making productions and selling by ourselves.
So we can control the quality of our productions by ourselves for you.
We’d like to receive your valuable suggestions for our products and make your idea come true.
New improvement: clearly printed on the female header connector, more precise and easier to use the wire
The Uno now uses an ATMega16U2 instead of the ATMega8U2 chip. Faster transfer rates and more memory
Control using ATMEL ATMEGA328P chip
100 percent compatible with the official version, for Arduino uno R3
We have always cared about the customer experience and improve the product function details
