Blank Slate is here to untether your grid from the grid!An ortholinear, wireless keyboard PCB, Blank Slate is designed to fit in cases compatible with the OLKB Planck rev5 and newer.
Features:
Wireless (BLE) and USB-C input
5 wireless profiles for connecting to multiple devices, including fast switching support
Available layouts: full grid, MIT (single centered 2u in the bottom row), and 2x2u
MX switches
Hotswap sockets and two different battery connector options, for a soldering-free assembly process
Custom two key combo for powering on and off, allowing for compatibility with existing cases with no power switch access (top left + bottom-right key for 3 sec)
Powered by ZMK firmware
LiPo (single cell 3.7v) battery support, with JST ACH and SH connectors and solder point fallback
Expected runtime between charges of at least a month
Requires BT 4.2 or newer for BLE connections
LeadFree HASL PCB surface finish
The following cases have been tested and verified to work with Blank Slate:
OLKB/Drop Hi Profile case
Gridiron
Typeau
Build Guide
This LiPo Battery is compatible with the Blank Slate.You find detailed information about compatible batteries in the build guild.A free 3D printable case by Sebastian Stumpf is also available.
Notes:
Only clip-in stabilizers are supported for the 2u switch layouts. Screw-in stabs conflict with some of the hotswap sockets.
Plateless builds are highly discouraged: the battery cutout in Blank Slate results in some switches being only partially supported from below by the PCB.
Cases that are entirely metal, including the switch plate, may impact wireless signal integrity. If using a metal case, a plastic or FR4 plate is strongly encouraged.
The ZMK firmware is powerful, but can be challenging to configure for new or non-technical users. It is not recommended for users who want to use a graphical application to reprogram their keyboard.
Photos of the completed keyboard are for demonstration purposes only.Please note that this is only the pcb and does not include switches, keycaps, or a case.
These top plate's fit's to the Planck Lo-Pro bottom case from OLKB.
Supports GRID, MIT (1x 2xU) and 2x 2U layout.
Compatible with Cherry MX switches, and MX clones (Durock, Gateron, Kailh, Zealio …)
Plate is 1.5 mm thick (FR4: 1.6mm)
With top opening holes (lubing switches without desoldering)
5 holes (2.5mm) for screws (M2-M2.5) to attach it to the bottom case
GRID SPACING (GS): 19mmFlexibility (left most flexible, right rigid): PLA - FR4 - Carbon - Aluminum - Brass
These plates are not compatible with Hi-Pro Planck cases from OLBK. Compatible plates can be found here.
