We are currently developing a product using TinkerBoard S R2.0.
I am looking for information on the standards we have obtained.
I would like to know the following information.Question 1.
Has TinkerBoard S R2.0 been tested to the following CISPR 35 standards?
IEC 61000-4-3
IEC 61000-4-6Question 2.
If so, can you tell us the test results? -
Hi @Tinker Engineer.
I re-wrote Tinker OS (Debian 10 V2.0.4) and measured the temperature.
(I did not change any settings on the TinkerBoard2S after the write).The result was that the CPU temperature reached 75°C (peak) after 30 minutes.
The following test conditions were not changed.
- Desktop screen displayed on HDMI monitor for 1 hour
- Tinker OS (Debian 10 V2.0.4)
- TinkerBoard2S included heatsink used
- Case not usedI would like to determine the cause of the abnormal heat generation, what else can I investigate?

Hi @Tinker Engineer
Test conditions are as described above.
- Desktop screen on HDMI monitor for 1 hour
- Tinker OS (Debian 10)
- Heatsink used
- Case not usedNo extra processing (e.g., web browser open in background) is performed.
Even so, it still generates heat of 66°C.What are the possible causes of the abnormal heat generation?

Hi @Tinker Engineer
Here are the details of the test conditions.
- Power on and desktop screen on HDMI monitor for 1 hour.
- OS is TinkerOS (Debian 10).
- Heatsink is used.
- No case is used.
- Nothing is placed around TinkerBoard 2S within a radius of 20 cm.
- Room temperature is about 25°C.
- The OS on the Micro-SD card is running.
- Bluetooth of TinkerBoard 2S is turned off after turning on the power. (To lower the temperature).
Under these conditions, the temperature was about 66°C.We also checked CPU usage and memory usage during the test with the top command.
- CPU utilization: 1% to 3%.
- Memory usage: about 250 MB.During the test, I am just using LXTerminal on the desktop screen and running the top command.
- What could be the cause of the abnormal heat generation?
- I would like to try a factory reset, so could you please tell me how to do it?
- If the unit still heats up abnormally after the factory reset, I am sorry, but is it possible to replace it? (Purchased in May 2022) -
Dears:
I am considering purchasing Tinker Board S R2.0 and am concerned about the CPU temperature rise.
When I operated my Tinker Board 2S under the following conditions, the CPU temperature reached about 70°C.
When Tinker Board S R2.0 is operated under the same conditions, how many degrees Celsius will it be?- Turn on the power of Tinker Board S R2.0 and display the desktop screen for about an hour.
- The OS is Tinker OS (Debian10).
- Room temperature is about 25℃.
- The attached heat sink is used.
- Case not used. -
