I have seen that there are M4 boards that support wifi modules now. Seeing as the M4 is generally a better board than the M3, are you looking at supporting wifi for an M4? I am looking to start aquiring my hardware soon so thought id ask for future proofing.
In addition, do we have to use the H Bridges that you list in the pdf or could I instead use say a dual channel 3.6A so that I can run two seperate sections with a greater draw on them due to accessories etc? This would dave me buying two 10A bridges that would make it bulky etc.
Many thanks,
Ash

Let me know which M4 board you are thinking about and I will see how easy it is to integrate the software onto. You can use any H-Bridge you want so long as it's digital control interface matches the L298N or IBT modules. See page 6 of the L298N datasheet.

Its been a few years since I have looked at the MC market as work has taken me in a different direction so I am a bit rusty so any advice would be welcome. I was looking at something like the Nucleo STM32WB55. It's a bit more expensive but you can get packages that include a multiprotocol wireless MCU such as here www.digikey.co.uk/product-detail/en/stmicroelectronics/P-NUCLEO-WB55/497-18384-ND/9857029 (was the first shop i found so havent checked to see if cheaper etc elsewhere). If this is not adequate to support all the functions required for dcc, could you possibly suggest any? Cheers, Ash |

I have looked at the STM32WB55 and you are correct, a little expensive. It would be possible to move the WIFI option so as to support WIFI on the STM32F411RE board as the WIFI is done with an ESP8266 module which currently I only support on the M3. To be honest the M3 is almost out of CPU when running the LC-DCC controller, the M4 has CPU to spare, so I will look at running the WIFI with the M4 and keep an eye open for the cheaper M4 with WIFI.

That would be great if you could, and as you say using an M4 means there is some spare capacity so you can add possible extra features like you posted in the RFID. Im in no massive rush for this as I will be going away with work for a while in the not too distant future.
If you need a hand with any research or development work then I am willing to lend a hand if needed. I have an electronics background that I am trying to move back to.
