Bluetooth Mesh daughterboard analog input

[John Smith]

Hi I am looking for a bluetooth Mesh daughterboard which can take analog input. Which daughterboard/chip would be best for this?

[Karl Ylvisaker]

Hi,

There is a multitude of possible board extensions with Nordic SoC's compatible with Bluetooth Mesh and capable of taking analog input.
Here is the list of the SoC that are compatible with Mesh functionality. If you are looking for full compatability with our Mesh SDK that would be the nRF52840, 52833 and 52832 SoC's.

Here is the list of third party modules that we recommend, all of which supports analog inputs.

Best regards,
Karl

Awesome I really appreciate the quick reply. Once I purchase one of these 3rd party daughter boards, how would I flash my firmware onto the Nordic SoC?

Another question: I noticed that the nRF52832 is the most popular chip on Alibaba Bluetooth Mesh modules. Is 52832 the cheaper option in comparison to 52833 and 52840? If so, what makes it cheaper?

I am very thankful for your responses.

No problem at all, I am happy to help!

To flash your SoC you will need access to pins SWD IO, SWD CLK, along with VDD and GND. To flash, you could use a DK or J-link.

Yes, there are certain differences between the models - a summary of the differences and more in-depth description of each SoC can be found here, in the nRF52 Series SoC tab.
I do not know anything about the pricing of different retailers in general, but the 52840 is our higher-end SoC, which in essence has more radio functionality and protocols, more hardware peripherals, and larger flash memory.
