Order fulfillment may take four to six weeks due to 3D printing of keycaps and case.
1 February 2025 update: Due to elimination of US customs' de minimis threshold, that there may be a temporary impact to order fulfillment time.

"It's even better than I expected, a flawless recreation of the Merc Stealth"
-Doug, patron of the first ErgoStrafer
"It's amazing. It has been exceeding every one of my expectations."
-Joe
"I am already IN LOVE WITH IT!!! I'm BLOWN AWAY by how good this thing is"
-Steve Sears a.k.a. The Drunken Bard
"Initial impression of build quality is nothing short of amazing."
Imagine the familiar layout and sculpted keycaps of the Merc Stealth, but with mechanical switches, high-performance electronics, and customizable open source firmware. ErgoStrafer is the modern answer to your gaming keyboard needs.
Faithful reproduction of the Merc Stealth gaming pad layout (placement, key shape, and key heights) as well as the same 5, 8 , and 11 degree tilt options ensures that ErgoStrafer will seamlessly replace the Merc Stealth you've relied on for years.
- Upgraded to use MX-style mechanical switches (brown tactiles, red linears, or your choice of any switch)
- High performance STM32F411 microcontroller for ultra-fast matrix scanning
- NKRO (N-key rollover): no limit on how many key can be pressed at a time
- Optional inclusion of new Z and X keys
- Up to three rotary encoders & knobs (with both press and rotate capability) can be installed place of the original Load/PrtScr/Save keys
- Open source QMK firmware with VIA compatibility gives you full control and easy dynamic key remapping for up to 32 layers. No more issues with driver incompatibilities and proprietary software.
- USB-C connector (USB cable not included)
- 3D printed keycaps and 3D printed case
- Includes keycap stickers
- Integrated buzzer
Mechanical switches are soldered into the PCB. There is no hot swap PCB available because the switches are so close together that there is no room for them.
By default, if one encoder is selected for purchase, we will install it in the Load key location (the top-rightmost switch). If two encoders are selected, we will install the second encoder in the PrtScr key location (below the Load key). If you would like a different arrangement, just contact us after order placement.
For black keycaps, we include white-on-clear keycap stickers. For white or translucent keycaps, we include black-on-clear keycap stickers.
USB cable available here.
Contact us for a custom quote (sales@custommk.com) if you would like different switches installed (i.e. you ship us switches, or have us order particular switches).
The full range of 3D printable material options can be found here or here.
Additional PCBs, switch plates, keycaps, and keycap stickers available here.
