Retro Keyboard in WK/WKL Layout

With the light retro style design, Class80 reminds us of the old days playing “FAMICOM/SNES“ (or whatever console you were playing at young age) with a couple of friends.

To be an remarkable DIY keyboard kit, MMStudio Class80 adopts the WK and WKL layout. The WK version is a general TKL keyboard with Win keys and a 7u spacebar at the bottom row, while the WKL is short for WinKeyLess, without Win keys and with a 7u spacebar at the bottom row.

VIA/QMK Programmable

MMStudio Class80 supports programs of VIA & QMK. For users who are not used to the WK or WKL layout, there’s nothing more convenient than remapping the keys by VIA without reflashing its own firmware. The changes can be saved on board, and be worry-free about losing the saved memory while unplugging and replugging the keyboard. Being compatible with QMK, there’s a great potential of being programmed and modded in the MMStudio Class80 for you to discover.

Soldered or 3-Pin & 5-Pin Hot-Swappable PCB

MMStudio Class80 comes in either a soldered or hot-swap PCB for the wired version, and a hot-swap PCB for the Bluetooth version. Hot-swappable sockets on the PCB are convenient for changing mechanical switches at will without having trouble soldering. Being both 3 and 5-pin hot-swap, you can install or change the general 3-pin and 5-pin switches to the keyboard at will. Without LEDs, the keyboard still supports switches to install in the south-facing direction.

*Note: For the Capslock key, when the stem is to the left (for the stepped Capslock keycap), the switch is south-facing; when the stem is in the center, the switch is north-facing.

Big size, Big comfort

Class 80 is 39.34cm long, 18.95cm wide and weighs about 3.5kg coming un-built. In addition, to meet the ergonomic, we made a 1.6cm tilted chin and the whole board’s typing angle is 7°.

High-End Build Quality

In the back of Class80, it is designed with a slope to maintain the stereoscopic design, followed the “FAMICOM/SNES“ stripe design to carve parallel lines in the back. In order to strengthen the board’s theme and break the single and heavy feeling of the board’s sideview, we deliberately CNC‘d a tolerance line on the side and a Famicom/SNES controller-like weight in the back of the keyboard, which can be taken apart from the board too.

Flexibility Inside and Outside

There will be both wired and Bluetooth version Class80 this time. In wired version, you can choose between soldered PCB and hot-swap PCB,while in Bluetooth version you can only choose hot-swap PCB.

The Bluetooth version includes a 5000mAh battery and it’s also available for customized keymap. Both version will have Capslock indicator. We also improve the inner brass weight design this time by adding screws on it to avoid scraping the bottom case.

Freely Switch Between Gasket Mount and Top Mount

Gasket mount keyboards are well-known for giving a cushioned and bouncing typing feel, as the plate is not in direct contact with the case housings. Some people, however, are not that into a gasketed mount keyboard. To meet these two types of demand, the keyboard is designed by ‘Double-S’ structure to solve the dilemma, with the bonus of retaining the beauty of symmetry.

This structure can keep a soft typing feeling as well as improve the lifespan of the PCB in such a weighted case, and therefore, the Class80 supports either plate/plateless gasket mount, or TOP / half-plate TOP mount for everyone to choose freely.

Aluminum Case with Brass & MMStudio Weights

The Class80 comes with an Aluminum case for a firm built. In the back of the keyboard, it is designed with a slope to maintain the stereoscopic design, following the ”FAMICOM/SNES” stripe design of carved parallel lines. In order to strengthen the board’s theme and break the monotonous and heavy feeling of the board’s side view, we deliberately CNC‘d a tolerance line on the side and put a Famicom/SNES controller-like weight in the back of the keyboard, which can be taken out from the board.

Solenoid and Buzzer with Poron Foams

Missing the sounds of a typewriter? Well, for the wired version, the MMStudio Class80 comes with a Solenoid and Buzzer. Just easily switch the buzzer switch, the keyboard will provide two pleasing sounds that you used to hear on a retro keyboard. To reach a top acoustic sound, the keyboard kit includes top Porons of plate foams, case foams and gaskets. With a whole Poron collection, the keyboard stands out in acoustic fields easily.

*Note: The bluetooth version does not support Solenoid and Buzzer.
