— -- Apple’s iPad Pro –- the company's biggest tablet yet – is set to go on sale Wednesday along with the Pencil stylus and smart keyboard that were introduced at the September event.

"The early response to iPad Pro from app developers and our customers has been incredible, and we're excited to get iPad Pro into the hands of customers around the world this week," Phil Schiller, Apple’s senior vice president of marketing, said in a statement.

Here's a rundown of what you need to know about Apple's newest products.

iPad Pro

Apple has one word to describe their largest tablet yet: Epic.

Coming in silver, gold and space gray, the iPad Pro measures 12.9-inches diagonally with a retina display. The width of the iPad Pro is the same as the height of the iPad Air, with 5.6 million pixels. The product has 10 hours of battery life, according to Apple.

The iPad Pro starts at $799 for the 32 GB Wi-Fi model; $949 for the 128 GB Wi-Fi model; and $1,079 for the 128 GB model, which comes with Wi-Fi and cellular capabilities.For the first time, there is a four-speaker audio system on the iPad with the new product.

"It puts up three times the audio volume of an iPad Air 2," Schiller said, while touting its thin width of 6.9 mm and weight of about 1.5 pounds at Apple’s September event.

The company is gearing the tablet to a vast audience ranging from designers and engineers to people looking to add enhanced productivity -– and of course entertainment -– to their lives.

Smart Keyboard

At $169, Apple’s new "Smart Keyboard," connects to the iPad Pro’s smart connector port, carrying power and data to the keyboard. There’s no need for a separate battery or Bluetooth pairing, making it easy to turn the tablet into a thin, light laptop that can easily be carried throughout the day.

Apple Pencil

The $99 Apple Pencil works with the iPad Pro to let the user sketch and design with fluidity and remarkable precision.

“Picking up Apple Pencil for the first time feels instantly familiar. It lets you make any number of effects, right down to a single pixel, giving you more creative freedom than ever before,” the description on Apple’s website said.

A built-in lightning connector on the Apple Pencil makes it easy to quickly charge the instrument.
