Important !! End of activation for Discovery STM32F407 V3 Shield based hardware

Recommended Posts

Hi,

three years after introducing the completely new Nucleo STM32F429zi / STM32F439zi V4 Shield design which allowed us to build 128x32, 128x16 and 192x64 displays  with the same hardware and lead to the EVO design, it is time for us to say goodbye to the old V3 shield hardware design. As a consequence we will stop giving out new activation keys for Discovery based PIN2DMD devices by the end of this year 31.12.2020. Firmware support will of course be continued as long as possible. Replacement keys with proof of destruction of the defective STM32F407 discovery board (picture of board physically destroyed)  excepted. Too many support issues, like cheap chinese discovery clones or wrong enhancer configuration, which could have been avoided with the V4 design made this decision necessary to save my valuable time. We will keep the V3 shield design on github for all those who want to upgrade their hardware by replacing their old V1 or V2 shield.

If you start a new pin2dmd DIY build here is a very good 4 based writeup

More work and more expensive, hmmmm

All for a few games, most of which are poor players

Pour moi ça ne me dérange pas au contraire  mais Oui beaucoup plus cher et difficilement faisable pour le pauvre utilisateur et surtout en rupture de stock assez souvent.

for me it does not bother me on the contrary but yes much more expensive and difficult to do for the poor user and especially out of stock quite often.

PCB and parts cost the same. Only  Nucleo is 3$ more and you end up with  a better more future proof hardware.

80% of all activations are already Nucleo or EVO based. I think it is time to move on.

I make PIN2DMDs for customers based on a highly modded "bare bones" shield board that is loosely based on the V3 board and I stick with older firmware because I come from the school of "If it ain't broke, don't fix it". This configuration has served me and my customers extremely well, with nobody reporting any compatability or performance issues to me for quite some time.

Unless I'm completely missing something by not updating to the Nucleo then I'd really much prefer sticking with the Discovery board!

Although maybe none of your customers contacted me with an issue, but 80% of the issues I got involved in were with discovery based hardware.
I don´t want to waste my time anymore  supporting the same issues over and over again while it can be easily avoided by using the new design which is there
for several years now.

Please accept my decision and update your design accordingly.

P.S. It just came to my mind that I got contacted by your customers, asking how to get into the onscreen menu and I finally found out that it was because you did not solder the buttons to your highly modded "bare bones" shield to save some bucks. That is a good example of how my time gets wasted.

lucky1,

I know its your project and you have every right to shut down what you don't want to support.  However I feel you are still going to get those questions regardless.  A possibility would be to see if someone else would be willing to take over the support and activation of the Discovery versions. That way you could either set up a page where a user could select which version they needed help with or possibly have inbox rules to route the messaging.  I don't really have skin in the game as I only just now even thought about starting this project.  I was going to go the discovery route mainly because I already had an unused board lying around.  So feel free to ignore this peanut gallery.

I still have 4 discovery boards I want to activate. Can I get 4 codes in 1 time by donating the correct amount of money?
I already have the discovery boards laying around.
