The QRP Labs Morserino-32 Pocket is designed by Willi OE1WKL (with immense help by Hari OE6HKE and other contributors) and produced by QRP Labs under license. M32 Pocket is the third generation Morserino built on many years of experience with Morse trainers. Note the above picture is representative only; we'll take a better picture as soon as possible; the final enclosure and knob are all in silver/grey-metal-coloured 3D printed PETG.

DOCUMENTATION: The Morserino user manual and all other documentation are on the Morserino github at https://github.com/oe1wkl/Morserino-32/tree/master/Documentation/User%20Manual

Morserino M32 Pocket includes:

Completely assembled and tested M32 Pocket, including all SMD components and through-hole components
3D printed enclosure as pictured including touch paddle, in silver/grey-coloured PETG

Shipping update

29-Dec-2025: We are shipping Morserinos at a production/shipping capacity limited rate of around 100/week. Estimates of likely shipping date for orders placed now, are on the shop page.

05-Dec-2025: Thank you for your patience. As you know, I had originally estimated that M32 Pocket shipments would begin in mid October. Unfortunately there were a significant number of unexpected production issues. I forgot to order the 3.5mm jack connectors; there were issues with enclosures, minor production issues, small differences between the production boards and the prototypes; even differences between the prototypes and themselves... I take full responsibility for all this, in hindsight I should have been less aggressive with my estimates. Anyway - it appears that everything is now resolved, and we will begin shipping on Monday 08-Dec-2025. There is a substantial backlog and it will take some weeks to clear it. Shipping out the first 500 orders is my priority. To date 1,092 Morserino M32 Pocket have been ordered. The second batch of 500 are in production and will be sent out when we finish the first batch. Current Morserino orders at http://shop.qrp-labs.com/morserino have a January 2026 estimate. Again my apologies, and thank you for your patience. 73 Hans G0UPL

18-Oct-2025: Our initial aim on taking the pre-orders for the first batch of 500 was to begin shipping in mid October. The PCBs and parts are here. However, we made a mistake on the parts list order. As a result I neglected to order the 3.5mm jack connectors. This issue didn't come to light until a couple of days ago, due to my trip to UK for RSGB convention last weekend, and our office move which also took place at the same time. So due to this ONE part that I am now waiting for again, the shipping will be delayed, maybe another 2 weeks... my apologies for my stupid error - Hans G0UPL.

Further updates will be provided at this page in due course.

What's new on M32 Pocket:

Hardware:

Larger, high-contrast colour display (1.9" TFT) for improved readability!
Tone generation and amplification via digital codec: resulting in a clean sine tone!
No LoRa as standard – but comparable functionality nonetheless – see the section on software!

Software:

The firmware of the M32 Pocket is based on the same platform as its predecessors, meaning that operation and functionality are virtually identical.
Version 7.0, which will be released at the same time as the M32 Pocket, has a number of new features (and these functions are also available for existing Morserino-32 devices after a simple firmware update:
- An option to flip the display view by 180°: important for left-handed operation of the M32 Pocket.
- Now the 5,000 most common English words can be generated.
- An option to display the output on the display in CAPITAL LETTERS.
- Bluetooth keyboard output: this allows you to practise with VBand (a popular online practice tool) without an additional dongle, but also to use the Morserino as an input keyboard for your mobile phone, tablet or computer!
- The new ESP-NOW WiFi functionality enables Morserinos to communicate with each other without additional hardware (comparable to the LoRa functionality of older generations): peer-to-peer communication on 2.4 GHz, without an access point or router!

Connection for transmitter/transceiver (to key the transmitter).
Connection for headphones or audio input and output for external devices.
Large, powerful speaker.
Adjustable frequency and volume of the side tone.
Easy operation via rotary encoder (with push button function) and additional push button.
Easy firmware update either via WiFi or USB (either through update program on PC, or, easier, directly through the browser; for this Chrome and Edge are supported).
Communication with external PC via USB (serial protocol): can be used for voice output, to set all parameters or to remotely control the Morserino functions (implementation of all these functions, e.g. at tegmento.org).

CW Keyer

From 5 to 60 WpM (25 to 300 characters per minute), in Iambic A, B or Ultimatic mode.
Memory keyer functionality (the memories are programmed via an external PC).
Paddle polarity switchable.

CW Generator

Generates random characters, call signs, common CW abbreviations or frequently used English words.
The length of the output words/character strings can be set.
Spacing between characters and between words can be increased (to simulate Farnsworth / Wordsworth spacing).
Can also play text files that can be uploaded via WiFi or Browser plus USB.
Can also play random words from these files.
Everything can be sent to other Morserinos via WiFi.

Some specific information related to the QRP Labs version, where there were some changes relative to the prototype to implement efficient and economic production: firstly here's a schematic of the QRP Labs version. Secondly here are some images of the PCB silkscreen (top and bottom), and the track layout (with and without groundplanes). The basic layout is very very similar to the original prototype but there were a few minor component changes, and the final QRP Labs PCB is manually-routed 2-layer not 4-layer.

3D Printed Enclosure files

https://morserino.groups.io/g/main/message/8145:
"There are four .STL files in the .zip (Case top, case bottom, knob, and internal display frame). Changes relative to the original files Willi OE1WKL gave me:

Knob: I think originally the fluted knobs had 11 grooves. We reduced it to 5, which makes it easier to print accurately.
Knob: we increased the amount of material between the knob shaft and the outer surface, to make the knob much stronger.
Internal frame: it has a small step in the bottom left pillar, which otherwise landed on top of an SMD component on my board layout.
Internal frame: height and position of the top left pillar was adjusted by Willi to suit the different dimensions of the 3.5mm connectors I used (which are different connectors to the ones in the prototype).
Internal frame: bottom left pillar slightly thinner, because the 3.5mm connectors used are longer (and thinner) than the ones in the prototype.
Case top: the FN button lever had to be shortened slightly because the push buttons I used in the production board are different parts to the ones in the prototype, and have a slightly larger height from the PCB surface.
Case top: we found that the left wall of the enclosure, where think fingers come down between the three 3.5mm connectors, were unacceptably weak, very easy to break off accidentally. Accordingly the left wall was thickened slightly and it is now much stronger.
Case bottom: the case bottom had to be enlarged a little to match the left-wall thickening mentioned above.
Case bottom: the bottom left hole plastic "pedestal" that the PCB rests on, didn't quite fit well due to the rear pin of the bottom left 3.5mm connector. As the connectors I used were long and thin, the pin same close to the PCB screw hole. This didn't happen on the prototype connectors which were short and fat, with pins on their sides. Note that this change was only made 2 weeks ago. The first couple of hundred Morserinos sent out, didn't have this adjustment. It can mean that the bottom left of the case doesn't appear to close tightly. It's quite easy to modify the bottom panel or the enclosure by removing the left half of the "pedestal" with wire cutters.

In the above list when I say "slightly" I don't know the exact dimensions off the top of my head but all of the changes were or the order of a mm +/-.

Some changes were made by Willi OE1WKL, some by my summer intern; the changes regarding the left wall thickening and the bottom left screwhole "pedestal" were made by Ross EX0AA.

As you see many of these changes were necessary to suit small changes in component dimensions. The original prototype BOM used several parts that were a) way too expensive and b) had poor availability, so wouldn't be able to manufacture in bulk. This was why I redesigned the PCB and BOM, to use lower cost, high availability parts. It made the project commercially viable, ensures it will be produceable for many years to come, and at the same time enabled the retail price to be reduced significantly compared to 1st and 2nd generation Morserinos.
