This is high quality OPEN-SMART UNO R3 board with type-C USB interface and it is based on ATMEGA328PB which is compatible with ATMEGA328P.

Red board and the colorful female pin headers make your project more impressive and unique. It is very popular for Arduino project production.

There’s a switch to choose the system supply voltage, 3.3V or 5V, which is very useful if you want to set the system to 3.3V to save power.

For example, you want to connect directly 3.3V TFT LCD / ESP8266 wifi / BME280 barometric sensor module for Arduino without level conversion module, you can set the board to be 3.3V level.


– Use for Arduino UNO bootloader

– Board type: for Arduino/Genuino Uno

– It is compatible for Arduino UNO R3 program, expansion shields, IDE.

– Use multi-color female header so that the interface is easy to identify and particularly noticeable.

– Use Type C USB connector, support positive and negative connection.

– Onboard 2000mA resettable fuse to protect power supply from the USB port.

– Leads out more GND, 5V pins, and I2C interface, so it is more convenient to connect it to peripheral modules without additional IO expansion shield.

– You can burn the program with the type A male to type C male cable.

– Onboard 5V and 3.3V voltage regulator circuit。

– This board is ideal for learners want to learn for Arduino and make creative projects.

– On-board test indicator LED, and you can program to control it.

– USB interface driver chip: CH340G, compatible with win7, win8,win10 linux, MAC OS.

– Microcontroller: Atmel ATmega328PB

– Working voltage: 5V or 3.3V.

– IO logic voltage: 5V or 3.3V

– Working current: 2000mA (Max)

– Digital I/O Pins: 14 (of which 6 provide PWM output)

– Flash Memory: 32 KB of which 512 Bytes used by bootloader



– Clock Speed: 16 MHz
