What\'s in the box: 3 Boards with/without cable（as picture shows）

Brand new, sealed package.

Purchase more than one and save money.

The board is the best board to get started with electronics and coding.

If this is your first experience tinkering with the platform, the board is the most robust board you can start playing with; it is the most used and documented board.

This is a microcontroller board based on the ATmega328PB.

It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button.

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. You can tinker with your board without worrying too much about doing something wrong.

The board is the first in a series, and the reference model for the platform.
