ESP32 pico D4 SoC heat problem
Posted: Tue Oct 13, 2020 3:26 am
I have designed my own PICO board using PICO D4 SoC with help of the document : https://www.espressif.com/sites/default ... eet_en.pdf. Everything works perfectly fine except heat is produced when chip is using WiFi functions. Device has to be always connected to mesh, otherwise I would have used sleep functions also.
I have tested with mesh code for a week and no issues found (without plastic case covered) except heating. My plan is to put the same board behind wall switch and will have a plastic enclosure also(no air flow will be there). Only SoC chip gets heated no other components are impacted.
According to datasheet temperature recommended is from -40 C to 85 C. I am unsure how can I proceed with this.
Is it safe to put behind wall switch?
Framework I use : ESP-MDF v1.0

Could someone help?
