Is it normal for the core to become warm?

Hello,

My Spark Core came today, woo!

I have a question though:

Is it normal for it to become a bit warm when it’s been on for a little while?

Mine came today too. It gets slightly warm. Power consumption was quoted as 100~300mA, which is 6~7 times that of an Arduino Nano, so i’m not very surprised.

Just wanted to chime in. It’s totally normal for the core to warm up slightly when running the wifi radio and powered over USB. It should never get “hot” – so if you have a custom powering solution make sure you’re within the normal range http://docs.spark.io/#/hardware/subsystems-power-regulator

@Dave Hi, thanks for replying. I’m using USB from my computer. I wouldn’t say it’s hot, it is only slightly warm. I just didn’t expect it to be warm though. It’s not a problem if that’s normal.

Yep, it’s normal; when the Wi-Fi module is on, it’s a power hog :slight_smile:
