Logitech Pebble Keys 2 K380s

Manufacturer specification · Logitech describes a compact and portable design; the official image shows no number pad or separate navigation cluster (inverted-T arrow keys, Delete in the function row).

Logitech MX Mechanical

Manufacturer specification · Logitech describes the MX Mechanical as the full-size model with an integrated numpad; the MX Mechanical Mini is the separate compact model. Low-profile construction is retained in switches and keycaps, rather than treated as a distinct full-size layout class.

Sources

Logitech Pebble Keys 2 K380s

Manufacturer specification · Logitech's specification lists the keyboard type as Scissor Keyboard, 60 ± 10 gf actuation force and 1.5 ± 0.3 mm total travel; there are no alternative switch options. Manufacturer FAQ describes low-profile scissor switches (chiclet-style) with round keycaps. No alternative switch configuration is asserted. Source-specific low-profile, round/chiclet keycap wording is preserved as implementation context; it does not establish a different scissor switching principle from other exact scissor-key models.

Logitech MX Mechanical

Manufacturer specification · One of three factory switch options (Tactile Quiet, Clicky, Linear); this SKU carries the Tactile Quiet switch, which Logitech describes as having a small discernible bump and little sound. Logitech does not name the switch manufacturer.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Logitech Pebble Keys 2 K380s

What it brings

Easy-Switch buttons move between up to three paired devices over Bluetooth Low Energy. Fn keys can be customised with Logi Options+ on Windows or macOS; on iPadOS, iOS, Android, ChromeOS and Linux Logitech says Options+ is not supported but the basic functions work without it.
Manufacturer source
Logitech describes a compact board that can slip into a bag. Its support table lists415g with batteries, and the keyboard uses two pre-installed AAA alkaline cells.
Manufacturer source Manufacturer source

What to check

There is no number pad, no backlighting and no separate navigation cluster, and the scissor keys have 1.5 mm of total travel.
Manufacturer source Manufacturer source
A Logi Bolt receiver is compatible but is not included. Bluetooth operation needs a compatible Bluetooth host; Options+ customisation is limited to Windows and macOS.
Manufacturer source

Logitech MX Mechanical

What it brings

Pairs with up to three devices over the supplied Logi Bolt receiver or Bluetooth Low Energy. Logi Options+ customisation is supported on Windows and macOS; on iOS, iPadOS, Android, Linux and ChromeOS Logitech lists basic functions without software.
Manufacturer source
The Tactile Quiet switch gives a small bump with little sound, which Logitech positions as the closest of its three options to MX Keys typing; Logitech rates the keys for 50 million presses.
Manufacturer source Manufacturer source
Logitech claims up to 15 days per charge with backlighting or up to 10 months with it off from a 1500 mAh battery charged over USB-C.
Manufacturer source Manufacturer source

What to check

At 433.85 mm across and 828 g this is the full-size model with an integrated numpad; Logitech offers the space-saving minimalist MX Mechanical Mini for buyers who want a smaller board.
Manufacturer source Manufacturer source
The switch type is fixed per SKU and Logitech does not state hot-swap support, so choosing Tactile Quiet, Clicky or Linear is a purchase-time decision.
