Description
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
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.

It works!
It does exactly what it says on the tin. My Planck keyboard is working wirelessly with no issues!
I'm not an expert maker, but I was able to figure everything out by reading the build guide and the links provided within.
I was able to choose a battery based on the documentation. If you are based in the USA, here's a link to the battery I used: https://www.amazon.com/dp/B0CNGZRK5Q?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_7
I was also able to download, modify and flash the ZMK firmware successfully by following the instructions in the documentation.
I loved my Planck keyboard, but having to connect it by wire was such a dealbreaker for me. If you want a wireless Planck, get a Blank Slate!

Affordable and comfortable BT "Planck" Board!
This board is a great entry into the planck world. The Blank slate comes pre-soldered, so it's basically part of a barebone-kit for a bluetooth planck style board. Plate and case are available at keycapsss.com too.
There are even two different connectors to choose from to connect your Lipo battery to, but you can also solder it on if you can't source one with the correct connectors.
Works flawlessly with ZMK firmware, which is well documented, feature-rich and easy to install.
