Nolltronics is now selling the EcoSteno! – a durable, affordable, entry-level steno keyboard for use with Plover (an open-source stenography engine).

The EcoSteno is now in production with the following features:

Noll Electronics EcoSteno
EcoSteno v1.0.17

EcoSteno Specs (v1.0.20 as of 8/21/2021)

  • USB-C port connectivity
  • Kailh gChoc switches – linear 20gf actuation (can be DIY spring-swapped with the right tools)
  • 32 keys (Split S-, Quad *, 4-segment number bar, two extra meta buttons)
  • Supports NKRO Steno, Serial Steno (TX-Bolt protocol before July 2021, Gemini PR after), and Qwerty mode, indicated by 2 LEDs on top of the board
  • 4×10″ footprint, <1″ height
  • 1/8″ laser-cut aluminum backplate with 1/4-20 camera mount1 and rubber bumpers
  • Powered by QMK running on GD32F103CBT6
  • Easily accessible reset button for end-user reprogramming over USB
  • Lead-free construction
  • $95 price point before shipping and taxes

Note 1: This allows the keyboard to fit onto most tripods that have a platform smaller than 3″. You may run into issues if you’re using a professional video-style tripod that has a much longer platform as there are nuts on the underside of the backplate.

The website should be decently polished, but feel free to contact us at if you spot any issues.

Newest Update

  • Big February Restock!

    We’re getting funds ready for the next big order so we’ll be listing the next two batches worth of EcoStenos to the next restock Tomorrow, February 25, 2022 at 7PM EST! We have all 100+ boards tested and assembled, with only the packing and shipping left (for the most part), which means we shouldn’t sell out as quickly as we have in the past. We’ll be aiming to have all of the boards shipped by the end of the first week of March, though we may also be able to get them out a lot faster. After this, the next (and smaller) restock may be ready around early April.

    The price of the EcoSteno has increased to $95

    We’ve been needing to increase the price for most of the past year, as we’ve been hit with shipping losses and increasing parts costs from the beginning (our processor costs alone have more than doubled!) but we wanted to keep the cost consistent through at least the first year. Our goal is still to keep the EcoSteno affordable and under the $100 price tag, and we don’t currently have any plans of increasing its price again.

    New International Shipping Courier

    We’ve had issues with USPS shipping internationally for most of the past year (extremely high prices to some countries, packages lost in purgatory for months, not generating the correct customs forms for some countries, etc) and are now moving to DHL, which should increase our international shipping speed and reliability. While a few countries may see an increase of a few dollars, others will have their rates slashed in half (Australia in particular) and most will remain similar with the average shipping cost per customer decreasing.

    Potential Issues

    All of the boards being sold this year so far have been from the same (new) manufacturer, but unfortunately we’ve already had a few RMAs from our earlier batch of ~60+ boards. We’ve traced the issue back to a bad batch of voltage regulators which seem to give out within one week of being powered on. To remedy this, we have been testing the keyboards in this upcoming batch by keeping them plugged in for at least a week, so hopefully any issues pop up here if they ever will at all. If you do end up receiving an EcoSteno which has this issue (all defects we’ve seen have come up within a week of sporadic use), shoot us an email and we’ll fix/replace it.

    Other Changes

    We’ve switched to using plastic spacers instead of an extra hex nut in between the PCB and the backplate. This makes it easier to assemble/disassemble the EcoSteno on our end. This change shouldn’t affect normal use at all, but it is something to note if you decide to open your EcoSteno.

4-30-22: We’ve sold out of our first big batch of the year (almost)! There’s a few stragglers that we’ll be adding into inventory as we finish testing and assembling them (mostly older boards) but the next big release may be another 6 weeks out. However, we have a few dozen new prototypes that should be out a lot sooner (within ~1-2 weeks)!

Update 4-12-22 : We’ll be adding a small amount boards into inventory tomorrow around 7pm EST and adding to this as more boards get finished. We’ll also likely be opening backorders for the rest of the boards we have on hand if we sell out of these initial boards since more are close behind.

We’ve sold out most of our big batch, but we still have ~80 boards left that we’re going to be adding into inventory as they’re completed, and are expecting to have a few dozen up for sale by mid-April (likely without a restock email).

Update 2/24/2022: There will be a large EcoSteno restock tomorrow, Friday February 25th at 7PM EST!

Update 2/24/2022: There will be a large EcoSteno restock tomorrow, Friday February 25th at 7PM EST!
Update 1/18/2022: All boards are now in the hands of the USPS! If you haven’t gotten an email with your tracking number and would like to have it, send us an email and we can forward it.

Update 1/7/2022: The first batch of the year has been sold! We’ll be packaging and shipping these boards over the next week, but don’t worry if you missed out because the next batch shouldn’t be more than a month away. We also have almost 200 boards that we’re considering opening preorders for so we can get the next big batch paid for and on its way sooner rather than later (but we’ll get this first batch out the door first). We’re getting ~10 shipped a day, so every board from this batch should be out the door by the end of the week.

Update 1/4/2021: We’ll be restocking the EcoSteno tomorrow at 7pm EST, January 5th! In case you miss out, we expect to have the next batch ready either late this month or early next month.

Update 12/9/21: The big order is in and we’re working on assembling over 200 EcoStenos! We’re aiming to get at least one batch out by the end of the month, and we’re also dealing with some new mounting hardware (which will hopefully speed things up even more!)

Update 11/28/21: We’re still waiting on a big order of EcoSteno PCBs to be assembled and shipped (from an order placed months ago), but we should be able to receive, assemble, and start listing them before the end of the year.

Update 11/8/21: We should have all of the most recent orders fulfilled by the end of the week, thanks for your patience! We should have another restock within a few weeks.
If you haven’t gotten a shipping number, contact us and we’ll resend it. It looks like some emails didn’t go through.

Update 10/22/21: We’ve been at work on the current batch, but with work and school ramping up, it’s taking more time than usual. The current plan is to list what we have completed before Halloween and allow backorder for the rest of the in-progress batch that we have on hand (if they aren’t completed by then).

Update 10/5/21: We received a batch of boards with GD32F103C8T6 chips and are running into issues getting them working with the CBT6 firmware although I’m hoping I can get them figured out this week. The large batch with the usual chips is still in production. We also now have a discord server!

Update 9/10/21: We’ve started the process of manufacturing in bulk and should have several hundred boards arriving mid-October. In the mean time, we will try to have another small batch ready earlier.

Update 8/19/21: Restock today at noon EST! This restock took longer than usual to show up but the boards are almost completely done (instead of partially done) so we should be able to ship them sooner than we could with the past restocks. Update update: With how fast this batch sold out, we’re looking at greatly increasing our capacity in the coming month.

Update 7/28/21: We’re dealing with a few outside issues that popped up that will be delaying this batch by a week or two, but we should have them ready to list by early August at this point.

Update 7/12/21: The raw materials for the third batch are just now arriving and we should be able to finish putting this batch together by the end of the month.

Update 6/30/2021: We’re finishing up cleaning and boxing the current batch and should have shipping numbers within the next day or two!

Update 6/24/2021: The second batch of EcoStenos have been sold out! Materials for the third batch have already been ordered and the next restock should be in mid to late July.

Update 6/23/2021: The EcoSteno will be restocked at noon eastern time on June 24th! We now also offer shipping to Canada and the UK! In case you miss this restock, we should have another batch ready within 2-3 weeks.

Quick update 6/8/2021: We’ve gotten in most of the materials needed for the second batch and should be announcing the next batch for sale within the next week or two!

Update 4/27/2021: We have vastly underestimated demand and have sold out of our first batch of EcoStenos in an hour! We are now hard at work getting these shipped and ordering materials for a larger second batch.
