Re: RaspberryPi 4: heatsink or fan

Hi,
Agree with you.
The only what can be done is to decrease the FAN noise like we done, but using PWM FAN control and dedicated cooling profiles that adjust the exact FAN speed to existing temperature conditions.

Re: Raspberry Pi 4 temperature

Hi, If you run PiCoolFAN 4 at 25%-50% of speed (ultra low noise) the on such environment it is fine. If during the time your application requirements increases temperature, the FAN speed will increased automatically, and when needs drop down, fan reduce their speed. You can use it also with a small ...

Re: Raspberry Pi 4 temperature

Hi, I agree with you, however in some case a big (like in above picture) cooling heatsink could do the difference. However it is depending to the application. So, all solutions are good. One solution is better for one application and another for other. You can use below of our PiCoolFAN4 heatsink an...

Re: Raspberry Pi 4 temperature

Hi, If you not like the FAN, it is FINE. However we tried to add to the PiCoolFAN4 as much as possible extra features + cooling, as usually people need a HW RTC with coin battery so we added it, as users need to know easy about the temperature we added 3 LEDs (Cold, FAN-running, HOT), as user need m...

Re: Moving Linux kernel to 4.9

Thanks for the feedback - I'm clutching at straws and it was worth a try. It sounds like you can send and receive any data you like as long as it's ff. More straw clutching: have you tried dropping the I2C baud rate? "dtparam=i2c1_baudrate=10000" in config.txt should do the job. Hi, I'm the bad man...

Re: UPS for Raspberry and USB HDD please recommend

Hi,

UPS PIco protect whatever is connected/powered to/from the Raspberry Pi on the J8 or USB sockets. Therefore if your HDD is powered from USB then OK.

The UPS PIco is able to supply up to 2 A if cable power is missed.

The most important is that you do not need to have any extra powering system, just put it on top of RPi, power as usual, and that is it. See here: http://www.pimodulescar...
