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

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).


When will Morserino-32 be available?

Kickstarter rewards will be sent out starting in December (if all suppliers and shipping agents play by the rules, anyway). Any Morserino-32s ordered from now on will be shipped starting in February. Waiting times depend on the number of orders coming in…

I missed the Kickstarter campaign - will I still be able to get a Morserino-32 kit?

Yes, but it will take a while (well, the Kickstarter backers also have to wait for a while). I will record incoming orders (just direct them by email to ). I will order the components in batches, and whenever a new batch is ready to be shipped out, I will inform you that kits are available now, and about payment options. As soon as I see your money coming in, I will ship out the kits. Be aware that first kits ordered this way will ship likely in February, as first I have to deal with the Kickstarter kits!

What will it cost?

The price for a kit with case (acrylic glass, laser cut and engraved) and removable 433 MHz antenna  will be 80€ plus shipping costs (7€ within Europe, 10€ outside Europe).

The price for a kit without case will be 64€ plus shipping costs (7€ within Europe, 10€ outside Europe).

These prices are the same as were valid for the Kickstarter campaign!

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

In which language(s) will it be available?

The language of the user interface will be 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.

Will the software be Open Source?

Yes. As soon as I will be at the stage of the final pre-release, the software and documentation will be published.

The schematics will also be published (and possible also the Gerber files for the PCB layout - this has not yet been decided).

While the software will be 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.
