Re: Charger NOT EQUAL with Power Suppy

@schluej Sorry schluej, but you re taking nonsense. With those 4.9Ah you are saying that LattePanda is using 4.9 A over a period of one hour (or 2.45 A over 2 hours or maybe 0.49A over 10 hours) :| . That is energy you are taking about. Normally rechargeable batteries capacity is measured with Ah (o...

Re: Absolute voltage limits for LattePanda

Thank you for your answers. @schluej Correct voltage for processor is probably provided by internal regulator to achieve stabilized voltage within tolerances. Processor is not powered directly from LattePanda power input. So input voltage (5V) does have nothing to do with 2% tolerance of processor v...

Absolute voltage limits for LattePanda

Probably question for LattePanda team... What are absolute limits for LattePanda input voltage? I know that Atmega 32U4 working voltage is between from 2.7 to 5.5 V but what about other components I'm asking this because I have 5.35 V power supply and I want to know if it is safe to power LattePanda...

Re: CPU temperature high

@acasta Hi. We doesn't have electric plan of LattePanda so this is only speculation... You can not use Arduino outputs directly for fan (as you say they are limited to 40mA per channel but also ATMEL CPU has overall current limit) but I think is safe to use 5V outputs that are right of Arduino white...

[DISCUSSION] Fans/Heatsinks/CPU Cooling Mods

I was looking at some HD video and after 15 minutes video playback started skipping frames and I noticed that generally computer was not as responsive as it should be. Later on I discovered that CPU was running only around 600 MHz or even less. I checked CPU temperature and it was around 83 degrees ...

[DISCUSSION] Creating image of LattePanda disk

I would like to create image of LattePanda disk prior to install all sorts of thing and eventually broke windows installation :D . I tried with CloneHD and Acronis True Image, but none of the programs sees LattePanda hard drive and thus can not be backed up. Any suggestions, how to backup initial in...
