Looking at other wireless modules on Digikey, its pretty common for modules to have a lower than 260°C temperature: https://www.ezurio.com/documentation/datasheet-bl5340-series (less than 300mm^3; 2mm high = J-STD-020 Tc of 260°C) -> from datasheet: Upper target 250°C, Absolute Peak Temperature 260°...

I have also come across this problem today. I am not an expert at this, but here are some additional things I have noticed that might help further discussion. There is a difference in temperature between the ESP32-S3 chip and ESP32-S3-MINI-1 module. ESP32-S3-MINI-1 requires Standard PCBA, while ESP3...
