nRF pincompatible BLE/Thread chipset

[NordicBlue2]

Hi,

Are there any Thread compatible nRF chipset that are footprint pin compatible wityh nRF52832? I understand/interpret that it is not possible to Firmware upgrade 52832 to support Thread as well as BLE 5.0? IF not footprint compabilte chipset exist, what are the closest imilar chipset in terms of size and external component integration?

Hi Torbjørn, 

You can have a look at this case for a table of pin to pin compatible. 

The nRF52832 is pin compatible with nRF52811 which as 802.15.4 support. However there is a limitation on the RAM and FLASH size on this chip. 

We have nRF52840 in QFN48 variant recently but it's not drop-in pin compatible with the nRF52832. You may need to make a new PCB for it. But it's the closest in packaging size if you are using nRF52832 QFN48.
