Overview

The Logitech MK540 Advanced Wireless Keyboard and Mouse Combo provides a dependable, full-size input solution for everyday computing. The keyboard features a 107-key layout with a spill-resistant surface and three adjustable tilt positions—flat, 4°, and 8°—so users can find a comfortable typing angle. Its standout feature is a rated battery life of up to 36 months on two AA batteries, which means extended periods between replacements. The included mouse offers a simple three-button design with a scroll wheel and an ambidextrous shape fitted with soft rubber side grips, rated for up to 18 months on a single AA battery.

Both peripherals connect through Logitech's 2.4GHz Unifying Nano Receiver, which occupies just one USB-A port on the host computer. This makes the MK540 easy to set up—simply plug in the receiver and the devices are recognized without additional software. As a renewed product, this combo delivers the same reliable wireless performance at a lower price point, making it a sensible choice for home offices, student workstations, or anyone who needs a straightforward keyboard and mouse without the complexity or cost of premium peripherals. The keyboard dimensions of 18 x 7.62 inches give it a standard desktop footprint, while the compact mouse at 2.4 x 4.4 inches travels easily alongside a laptop.

Key Features

PLUG AND PLAY WIRELESS COMBO: Connect your keyboard and mouse with one tiny Logitech Unifying USB receiver. You’ll get a reliable – and encrypted – wireless connection up to 10 meters away with virtually no delays or dropouts.

FAMILIAR TYPING EXPERIENCE: The keys have been optimized for improved accuracy and reduced noise – and your fingers will immediately feel at home on the familiar key surface and layout. The palm rest and adjustable tilt legs keep you comfortable for long stretches at the desk.

CONTOURED COMFORT MOUSE: The wireless mouse’s contoured shape and soft rubber side grips are designed to fit comfortably in either your right or left palm – and enhanced tracking and precise cursor control keep you in command.

PRODUCTIVITY AT YOUR FINGERTIPS: Convenient and essential hot keys give you direct access to media, calculator and battery check functions. Preset Fn keys can even be personalized in Logitech Options to meet your specific needs.

RELIABLE AND HASSLE-FREE: Your keyboard won’t require new batteries for 36 months and your mouse stays powered for 18 months. The keyboard is spill resistant to 60ml of liquid and abrasion resistant key printing ensures your keys won’t quickly fade.
