Wireless controller

[GS2]

Hello, can somebody help me to select the STM32 controller and it's developer board for my first project that involves:
wireless air mouse with keyboard and TV controller?

[GS2]

I am wondering if you can tell - can I use this as development board  for STM32WB55RG too:

Of course it can be done - but is it worth it?

With a genuine ST Nucleo board you get:

• Known-good, supported, documented hardware
• Built-in support from tools, software, etc
• A genuine ST-Link - with VCP - included
• Ready-to-go examples, tutorials, etc
• Because it's a well-known board, people will know exactly what you're talking about when you come here with questions
• etc, etc, ...

You won't get any of that from Ali Express.

I would strongly suggest that you at least start with a genuine Nucleo board - and use that to gain familiarity with the chip and the tools, etc.

Once you have a good grasp of the chip and the tools, then you will be able to evaluate other boards and decide whether they suit your needs, and you will have the necessary skills to adapt to other boards.

Yes, I completely agree with you. But I found from AN5165 that this Nucleo board PCB have 6 layers! So when I finish development I will have a problem - I have only free software to design 2 layers PCB. I am wondering - Why the Company do not offer small PCB or module for STM32WB55RG and RF part, so it can be surface mounted on customer 2 layers PCB ? I am sure that this will increase STM32WB55RG sales!

ST do have modules; eg,

There are also 3rd-party modules

And other small boards; eg,

Yes, STM32WB5MMG is great, also seems 3rd-party modules are missing.

Hi Andrew, just one more question:

As I am planning to use STM32WB5MM module - will it be better to start with STM32WB5MM-DK ?

Hello @GS2 

I suggest you create a new post for each question since we want to give more visibility to each topic discussed on the community. So, others can use those answers too. On the New post, you will also receive an answer from me, @Andrew Neil or other Community members.

Best Regards.

STM32WB5MM module uses STM32WB55VGY microcontroller:

NUCLEO-WB55RG would be fine for evaluating that:

The STM32WB5MM-DK and NUCLEO-WB55RG both include an ST-Link.

The STM32WB5MM-DK has some "extras" like OLED display, digital microphone - only you know if those are useful to you. If they're not useful to you, then they'll get in the way!

The STM32WB5MM-DK is about twice the price.

Thank you Andrew. Yes, I will stick with P-NUCLEO-WB55RG.

[GS2]

OK. I will create a new post for each question.
