@HEINZV Thanks for the clues. Now all modules are programmed in the Arduino IDE. Absolutely all modules - Low power mode | programming in Arduino IDE | MySensors – 00:31

Truth were nuances. Had to remove all the drivers for J-LINK, remove nRF GO. Then I installed the j-LINK Windows v640 drivers. Then again I installed nRF GO. And the most important point when installing nRF GO refuse to install drivers for J-LINK. nRF GO works with both my Chinese j-LINK clones

Hi,
You design it for some nice enclosure???

PCB is prepared for installation in the case, there are mounting holes, feed-through saws. As long as this device is without the case, you can make the case yourself, all conditions are created for this. Later it will be offered in the case, but that's another story...

The one ordered soldered module is still in transit (or I did not get it so far).
I have not sent it to you yet, I have a problem with China, I am still waiting for new modified boards, I want to send you the latest version, please wait, do not cancel the order. I will also add new PCBs to the package (there are no changes in the components and numbering, just placed differently)
The device has become thinner, less in height, all electronic components have been removed from the side of the batteries, and PCB have been prepared for mounting in the case.
Making your characters is easy.
.. Absolutely any font, you are limited only by the memory capabilities of the nRf52. .. And it makes no sense to store all the characters if you need only numbers, it saves space very well.

Below another picture of the ePaper output. I have tested the idea with two fonts: The larger one for the non decimals and a smaller one for the decimal. I'm using the GxEPD standard e-Paper library in my latested sketch, as it's easier to use, has more fonts und is ready for more ePaper modules/sizes.
It is just an intermediate state (batter symbol, larger font missing etc.).
It's great, I am very glad that you are doing the further development of this direction.

Thanks for the tips, very hard to find information. I have a pair of j-link adapters. There are also several different clones of st-link v2. (but I don't have a linux machine now.) I'll try nRFgo Studio tomorrow. Earlier I wrote that I assembled my Assembly nRF52832 (dc-dc), no problems in the Arduino IDE(chips in the ribbon, see the link below). So I thought that the E73 modules do not work because of a slightly different circuit (see photo without cover) in the circuit no inductance on the DCC pin and no connection outputs through inductance to the DEC4 pin.

nRF Go studio
How do I unlock (if locked) E73 with nRF Go studio ? What should be done, what actions?

CBYTE nRF52832
I have a question for you, teach:). Do you use CBYTE nRF52832 and Arduino IDE? I was unable to run these modules. How did you manage that? Did you add inductance to the circuit? I assembled my own nRF52 modules according to the scheme DC-DC from Datasheet (I needed a module on components of size 0603 and 0805 for convenient soldering), the scheme worked and the device is perfectly stitched through the ARDUINO IDE

@heinzv Yes, I plan to add one-tenth resolution.
Convert numbers and letters to an array in C is simple. I use a program TheDotFactory. http://www.eran.io/the-dot-factory-an-lcd-font-and-image-generator/
I would be glad if someone made his version of the software in the public domain.
Please show photos of your assembled working device.
