ESP32-S3 Zero heat

[Ignperlup]

Hello, I'm using this amazing project on gigs with my band, and for the moment everything was fine!
I'm using the ESP32-S3 Zero I bought here: https://es.aliexpress.com/item/1005007624988332.html?spm=a2g0o.order_list.order_list_main.39.4d31194d2rjdmK&gatewayAdapt=glo2esp

I'm feeding it using a USB-C conector to 5V and I notices that the shield is very hot, let's say to the maximum point that I can bear to keep my finger on the shield. To be honest I don't know if this is normal, I tried with 2 ESP32-S3 zero and it is the same, but I don't have any temperature sensor to measure the real temperature, maybe it has a normal temperature but I'm afraid that something happends when I'm playing live.

Regards

Hi,
The Zero board does tend to run warm. My one is not very hot but some other users have reported it getting quite hot like yours.
Electronic devices can often work happily at temperatues that burn human skin, but I myself don't like to have devices that are this hot.

Another user added a stick-on heatsink to the metal shield, like below. I would suggest this would be worth doing. There are lots of these around and it should not be too hard to find some.

I use the Zero board on my mini board, and have run it 4-5hrs continuously on multiple sets. I found that the heat is very manageable if bluetooth is off. Hence, built a DIY wired 3.5mm midi out to pair with my Zero. For reference, I used this reference to build the midi out board: https://diyelectromusic.com/2021/02/15/midi-in-for-3-3v-microcontrollers/
