Retro Gaming Aesthetic, Modern Performance

The 80 Retros GB40 is a compact 40% mechanical keyboard kit that combines a retro gaming aesthetic with modern, enthusiast-grade features. It offers a high-quality typing experience with extensive customization options, making it a versatile choice for users who appreciate both its unique design and its technical performance.

The case design is inspired by classic handheld gaming consoles from the late 1980s, featuring details such as a non-functional speaker grill, rear A/B buttons, and a decorative joystick piece. The entire chassis is constructed from CNC-machined 6063 aluminum for durability and a premium feel.

Gasket Mount and Sound Profile

The GB40 utilizes a gasket mounting system to deliver a superior typing feel and acoustic profile. Eight silicone cushions isolate the FR4 plate from the aluminum case, which dampens vibrations and reduces high-frequency sounds. This creates a softer, more refined typing experience compared to traditional mounting styles.

To further tune the acoustics, the kit includes a multi-layer dampening solution:

- Poron Plate Foam (3.5mm): Positioned between the plate and PCB to reduce hollowness.
- IXPE Switch Pad (0.5mm): Placed under the switches to modify their sound signature.
- Poron Case Foam: Fills the bottom of the case to eliminate resonance and deepen the sound profile.

Connectivity and Customization

Engineered for modern setups, the GB40 features tri-mode connectivity. You can connect via a wired USB-C connection, Bluetooth 5.2, or a low-latency 2.4GHz wireless connection using the included receiver. A 3000mAh battery provides reliable endurance for wireless use.

The hot-swappable PCB supports both 3-pin and 5-pin MX-style switches, allowing you to change switches easily without any soldering. For complete control over the layout, the keyboard is fully compatible with QMK and VIA software. This enables you to remap keys, create custom layers, and program complex macros through an intuitive online interface, which is essential for maximizing the functionality of a 40% layout.

Frequently Asked Questions

What is a 40% keyboard layout?

A 40% keyboard omits the number row, function row, and navigation cluster to create an ultra-compact footprint. Numbers and symbols are accessed through layers, which you can activate by holding a dedicated key (like "Fn").

Is a 40% layout difficult to learn?

There is an initial learning period. However, once muscle memory for the layers is established, it can offer an efficient typing experience. Full QMK/VIA support allows you to customize the layout to your personal workflow.

What do I need to complete this kit?

This kit is all-inclusive. It contains the case, PCB, plate, foam, stabilizers, switches, and keycaps. The only requirement is assembly.

Why is QMK/VIA important for this layout?

The functionality of a 40% layout depends heavily on layers. QMK and VIA are powerful, industry-standard tools that provide an easy-to-use graphical interface for remapping keys, creating custom layers, and building macros without any coding.
