https://devzone.nordicsemi.com/f/nordic-q-a/26295/temperature-rise-of-a-circuit-board-using-nrf51822Do I have to temperature dissipation? I attached temperature sensor on my board with nrf51822. I removed copper layer of around the temperature sensor. But it seems the temperature getting higher than normal. But I didn&#39;t do anything special in the nrf51822en-USTelligent Community 13Thu, 26 Oct 2017 03:36:11 GMThttps://devzone.nordicsemi.com/thread/103500?ContentTypeID=1Thu, 26 Oct 2017 03:36:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9de91137-0ce7-486e-91df-d825e373e7dbRK<p>well the nrf51822 has a temperature sensor on it so you can work out from that if the chip itself is heating up. However I can&#39;t think of a case in which the chip takes anywhere near enough power to actually get warm at all, it&#39;s a low power chip. If you have a temperature rise it&#39;s far more likely to be from another component on your board (like an LDO regulator).</p><div style="clear:both;"></div>
