Cheapest Wireless MCU

Luis Alberto

Hi all,

I'm looking to develop a proprietary start network that may support around 30 devices, with very low bandwidth (pretty much just a keep alive and a sensor state), the network would be spread over 30 meters (radio coverage of 30 meters or that it can reach 30 meters with hops).

I'm looking for the cheapest wireless MCU device that works on US Free bands (subGHz, 2.4GHz, etc.). If any Transiver+MCU combination is cheaper than the wireless MCU I'm interested in that as well, I'm just assuming that it will not be the case...

I have seen NRF52810 but I was curious if there is any cheaper than this, as the application does not requires lots of resources.

    Hi

    The nRF52810 is the cheapest nRF52 device we have. We do also have the nRF51822, which is from the previous generation of chips. The price difference is not big though, so I would recommend the nRF52810 as the SDKs and SoftDevices are still updated to be compatible with it, leading to better libraries and drivers, and better options for support. The nRF51 family stopped being supported in SDK v.12.3 which will make the development somewhat harder in my opinion. This decision will be up to you of course, but those would be the two main options.

    You can contact the regional sales manager of your area if you need more sales related info on these products. If you don't have the contact info of your region's RSM, please fill out our sales related questions form and you will get in touch with them.

    Best regards,
