The cheapest entry-level stenography keyboard!

SKU: 10010170 Category: Tags: , , , , , ,


The Ecosteno is an entry-level hobbyist stenography keyboard designed for use with Plover, an open-source stenography engine (part of the Open Steno Project).

Featuring Kailh Pro Pink linear switches at 20 gram-force (about 20cN) actuation, the Ecosteno offers a light touch desirable for lengthy dictations yet heavy enough to be comfortable for beginner stenographers switching from mechanical keyboards. The switches can be spring-swapped for a lighter (or heavier) touch.
If your international shipping rate seems unusually high, contact us and we’ll see what we can do! Generally, USPS is significantly cheaper, but often gets lost in transit for 1+ months while DHL can deliver in as little as 3 days.

We also have extra USB cables if you would like one, as well as the Multisteno if you would like some extra keys!


  • Pinout changed to match the Multisteno – be sure to use v1.1.x firmware!
  • Mounting holes shifted to be closer to edge – backplates are different!
  • Switches changed to Kailh Pro Pink switches (only a color change)
  • Added ground plane for better ESD protection


  • Slight changes to component selection and footprints
  • Changed the microcontroller to the GD32F103C8T6 on all early 1.0.20 boards due to shortages (functionally identical)


  • Steno serial protocol changed from TX Bolt to Gemini PR (you can still flash TX Bolt firmware if you would prefer)


  • Backplates are now laser-cut 5052 aluminium instead of hand-drilled 6061 aluminium
  • Decreased red LED brightness to match green LED
  • Added boot 0 switch for easier manufacturing (shouldn’t be touched unless you know what you’re doing)


  • Initial Release


  • USB-C connectivity (center top edge of keyboard)
  • 20gf linear switches (Kailh Pro Pink)
  • 32 keys with 4-segment number bar, split S-, and quad *
  • 1/4-20 camera mount
  • 1/8″ thick aluminum backplate w/ rubber feet
  • 4×10″ footprint, <1″ height
  • Gemini PR protocol, NKRO steno, Qwerty mode, and Symbol layers
  • 2 indicator LEDs (red & green)
  • Reset button for easy reflashing
  • Powered by QMK on GD32F103C8T6
  • Lead-free construction

What’s in the box:


Once you plug it in for the first time, Windows will take a few seconds to a minute to automatically install the drivers. During this period, the keyboard may not function correctly.

After this process is complete, it is recommended to unplug and replug the keyboard at least once. Then you should be good to go!

Plover Serial Port Configuration

v1.0.19 and newer: Gemini PR protocol (9600 baud rate, 8 data bits, 1 stop bit, and parity N).

Pre-v1.0.19: Standard TX Bolt protocol (9600 baud rate, 8 data bits, 1 stop bit, and parity N).

We’ve currently only been able to test on Windows 10 machines, but so far every customer that has tried on Linux and Mac has had it work just fine!

Here’s a quick video going over the general use of the Ecosteno (pre-v1.0.19).

For v1.0.19 and later, select Gemini PR instead of TX Bolt in “Stenotype Machine”.

Every Ecosteno is made by hand in our workshop,
and as such may contain variation from board
to board such as scratches on the backplate
and other minor cosmetic imperfections.

  1. NL

    The ecosteno is one of the more affordable hobbist steno machines currently out there and the machine I liked the most- a win-win! Nolltronics is also very responsive to emails and on the discord which I appreciate greatly as a very beginner steno learner! It was so easy to use with plover- I had no troubles with it when I first connected it to my computer- another thing I appreciated. I love the sleek and smooth design of the board and the keys along with features like having a mount for my tripod and a number bar row, unlike some other options. The ecosteno just checked every box for me and I love it!

    I’d always wanted to learn Steno and with this machine (and plover) I can!!! It is very easy to use, the keys are very clicky and comfortable to write with and the packaging was top notch! I love the carrying case as well, so that my machine can be protected when not in use. Thing is, I haven’t STOPPED using it!!! It’s awesome. Get you one ASAP!!!

    Shipped extremely quickly! I was prepared to wait weeks but days after I placed my order I received it. Easy to set up on my iMac mini when following their guide. They also sent a nice sticker 🙂 Using the keyboard is nice. I don’t have anything to compare it to but the keyboard is sensitive enough/springs are light enough for a beginner.
    I got the Ecosteno with the USB-C to A and didn’t get a carrying case.

    I really appreciate what you guys do. I needed something affordable to practice court reporting before I invest in a $4k machine and this came in clutch. Works great with my Macbook and Plover. Carrying case is great. Also, fast shipping. Thank you!
