こんにちは@Tinkerエンジニア、 私たちに教えるのにあなたの助けをありがとう。

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 61000-4-6 Question 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 used I 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 used No 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?

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.
