Extra
Here you can get single PCBs. Almost all HMKB keyboard enclosures come with a PCB included. Only the HMKB-60 and HMKB-65 are also offered as PCB-less kit. Adding an extra PCB here, makes sense if you like to have a spare one or if you want to build a second pcb-plate-switch-stack, for swapping.
Design
All printed circuit boards for HMKB enclosures are designed by Evelien. The Plain60-C, the Eon40 and the Eon87 were already present before the HMKB line was designed, whereas the Eon65, Eon75 and Eon95 were design specifically for HMKB. These PCBs support the most common layouts and avoid combining too many layouts at once. This results in a less perforated bottom row, which leads to a more pleasant build experience. All PCBs have a fuse and an ESD chip present, to protect the MCU and other parts of the PCB. No fancy stuff like underglow LEDs since the HMKB enclosures don't allow for much light to escape the case anyway.

Eon40
The Eon40 is the standard PCB for the HMKB-40. It is a 40% ortholinear PCB. The HMKB-40 was designed specifically for this tiny PCB. Notable is the non-standard distance between the keys. It is 19.00mm instead of the standard 19.05mm. This slightly denser design is common for smaller ortholinear layouts.
Plain60-C rev2
The Plain60 is the standard PCB for the HMKB-60. It was one of Eveliens first PCBs. Since the first version which had Mini-USB it was updated to USB-C. The latest revision adds speaker support. It is also compatible with standard tray-mount cases. Most standard 60% PCBs are compatible with the HMKB-60.
Eon65
The Eon65 is the standard PCB for the HMKB-65. It is based on the Ta-65, one of Eveliens earlier designs. The Eon65 has a standard 65% size. Other standard 65% PCBs like the KBD67 fit the HMKB-65 as well.
Eon75
The Eon75 is the standard PCB for the HMKB-75. It is custom designed for the HMKB-75.
Eon87
The Eon87 is the standard PCB for the HMKB-80. It is a TKL PCB with split spacebar support. Other TKL PCBs might fit the HMKB-80 as well, the KBD8X MARK II looks like it does, not confirmed.
Eon95
The Eon95 is the standard PCB for the HMKB-95. It is custom designed for the HMKB-95.
Layouts
Please take a look at the dedicated layouts page. All (or most?) possible layouts are shown there.
Info
Depending on the combination of your plate and PCB, many different layouts can be build. To see exactly which layouts you can build with your desired HMKB size and version, please go to the layouts page to learn more.
The images are 3D renders and are for illustration purposes only. The final colors may differ slightly.
For powder coating the parts are put on racks. This will leave a little mark. It is usually at one of the holes. Since the holes will be covered by the bolt heads, these marks will not be visible when the case is assembled. Although highly unlikely, it is possible that dust particles may be caught in the powder coating.
The bending process leaves slight marks. They are not a concern for the powder coated steel parts and not be visible at all. The stainless steel parts are not powder coated but bead blasted instead. On all of the prototypes the bead blasting removed those marks completely and they were not present anymore. Still, there is a small chance that some stainless steel parts may show slight traces of these marks, even after the bead blasting.
The angles of the flanges may not always be perfectly 90˚. Though unlikely, a deviation of up to 1˚ can occur. This would still be hardly noticeable.
The switch plates can have scratches.
None of these effects are considered a defect.
Shipping world wide, with just a few exceptions. See the current shipping prices over at this page.
Updates regarding shipping will be posted on the HMKB discord server. Some of the updates will also be posted on the group buy page on geekhack, though the discord server should be regarded as the main source for updates. The Newsletter will also provide some updates.
