I’m trying to find a Bluetooth/Wifi module that will work at extreme temperatures. Any pointers?
i saw the PTS of BX31 module having Ambient Operating Temperature -40°C to +85°C
We have some modules having high temperature range from -40°C to +85°C for Ambient Operating Temperature and -40°C to +105°C for Ambient Storage Temperature. You can refer to the link below for more details. Basing your technical purposes, you can choose one of them
