Hi all - starting to try some experiments with the PICO and noticed the CPU gets pretty HOT. That’s outside of a case or any form of enclosure or operating over time.
Various places on and around the CPU are bouncing around 140 - 150F
Everything is working fine.
The power is connected directly to the LEDs, with the 4 DIN pins wired up to the PICO.
But got to wondering whats normal?
And if reducing the voltage back-feeding the Pico to more like 3.3 v would help reduce the heat?
I did notice the power regulator i am using currently is reducing 12v to about 5.1 or 5.2 volts. which means right now its being supplied with a slightly high (0.2v) voltage in the configuration i used to measure the temp.
Whats a normal operating temp for these chips?
Was considering putting a heat sink on the CPU but was not sure if that would interfere with the radios.
