Naturally, some questions tend to pop up again an again, so maybe it is best if I answer them here for the benefit of all of you:

Choice of LiPo battery for the Morserino-32

For my prototypes I used a small 600 mAh single-cell LiPo battery that is commonly used in RC devices like quadcopters etc. The brand I use is „Tattu“ and has the following specs (see or - the latter has slightly different specs and doe NOT fit under the heltec module!):

Tattu 600mAh 3.7V 30C 1S1P Lipo Battery Pack with Molex Plug
Capacity: 600mAh
Voltage: 3.7V
Max Continuous Discharge:30C (18A)
Weight: 15.7g
Dimensions: 60 x 19 x 7mm

See the picture below; Tattu is the battery at the top).

Of course you can use similar batteries from other manufacturers; in order to fit under the micro controller the maximum dimensions are: 65 x 20 x 8 mm.

It must be a single cell LiPo (nominally 3.7 V), and should have a Molex plug (because a cable with such a connector is part of the kit - if you use a battery with a different type of connector, you need to supply your own cable for connecting it to the Morserino-32!).

You can use larger batteries if you mount them under the PCB, on the bottom plate of the case. To give you more flexibility, the kit will contain 6mm and 12mm distance bolts for mounting to the bottom plate. This means you can use pretty large LiPos, as long as they are < 10 mm thick. If you use the 6mm and 12 mm stand-offs in combination, you could even use batteries that are up to 16 mm thick! You have to make sure that you mount the battery in such a way that it is impossible for any sharp metal spikes to scratch the surface of the battery - this could lead to fire or explosion!

One option would be this type (in the picture the battery at the bottom): or even that one, for even more capacity: (but be aware that this one does not use a Molex plug - you would need to find a cable with a suitable plug to connect this to your Morserino-32).


Is Morserino-32 available?

Yes.  Waiting times depend on the number of orders coming in. Currently the waiting time is about a month.

What does it cost?

See the Morserino-32 page for pricing.

LiPo battery is not part of the kit and has to be sourced separately.

How can I order a Morserino-32 kit?

Order  by email to (click on the email address). 

I will confirm to you that you are on the waiting list, with an estimate when the kit will be ready to be shipped. I assemble the kits in batches, and whenever a new batch is ready to be shipped out, I will inform you that your kit is available now, and about payment options. As soon as I see your money coming in, I will ship out the kit. 

You want to order more than one kit?

No problem. There are prices for bulk orders:

2 - 4 kits: normal price, but shipping fee applies only once 

5 kits: 390€ (78 per kit), plus single shipping fee 

8 kits or more: 76€ per kit, plus single shipping fee.

US$ exchange rate: 1 € is approx. 1,17 US$

In which language(s) will it be available?

The language of the user interface is  English only (at least for the first release). 

The decoder recognizes the characters of the International Morse Alphabet, and currently also the extra characters for German (special characters for other languages might be added in the future - this will depend on user requests for such characters).

The documentation (user manual) will initially be available in English and German. Other languages might follow, if there are volunteers in the user community who will do the translation.

Is the software Open Source?

Yes. the software and documentation (including schematics) are  published on Github.

While the software is under a very liberal Open Source license, anything pertaining to schematics and layout will have restrictions concerning commercial use - amateurs will be free to make use of it, but mass production (say, more than 50 pieces ;-) for commercial reasons will not be allowed unless a proper license fee has been negotiated.

Is the Morserino-32 available also as an assembled device, ready to use?

No, I do not have the resources to assemble kits. But the kit is easy to build, it takes about one hour. All SMD parts are already populated on the PCB. It is also an ideal project for your club! Build it together (more expereinced builders can help thos with less experience), and tehn practice Morse code together!

Are there any distributors for the Morserino-32 kits?

Currently there are no distributors. Calculation is very tight, so there are not sufficient margins for any distributors. I am assembling the kits myself (I am a very low cost worker ;-) and I am shipping to any country in the world (with certain exceptions, like North Korea), at ver low shipping rates.
