Description

Extreme75/Hifinger75

Hey Geekhack,
this is a small keyboard we like to refer to as mini980.

Let's look at the layout first:

Wired

BLE

First of all, this is a 74 keys keyboard, based on layout 980 but some different, such as the key; and ‘’ next to L,changed to the Shift + K and Shift+L, and the [] key next to P has been reduced to Shift +\(the key below BS).then 6.25 spacebar spit to 2.75 U+2.25 U，the purpose of the spacebar modification is not to need to buy a big set of keycaps, the second is to be able to add a custom key for this keyboard
Next, look into the structural features,

Gasket mount, it involves a 1.5mm thick PC plate with a rubber o-ring between the plate and PCB, we add a o-ring gasket as above pic. It will also use 2.5mm poron tabs for the plate. This should help with achieving a softer typing feeling，We plan to make both Bluetooth and wired versions of the pcb.

Changes:
Extreme75% first prototype typing experience was not good, because we designed is 4.75 mm PC plate, the advantages of the plate is a good support, the keyboard will feel very full, but there is no soft in gasket feel.
So after a second of entanglement, we decided to revise the drawing to make a new prototype, We kept making prototypes until we were satisfied.

1. The plate thickness was 4.75mm in the first version which was too thick, because the hard type feeling, we changed the plate thickness 1.5mm in the new version. The benefits of doing this are known to increase flexibility and soft typing.
2. Added Bluetooth
3. We changed the weight design to be more thematic
4. Added Flex cuts to the pcb to help with the typing experience
