  1. Hi @Sanko_bs Sorry, I seem to be having problems posting the article, I will republish it in this way. When I operated my Tinker Board 2S under the following conditions, the CPU temperature reached about 70°C. ==> It is not normal for Tinker board 2S to reach 70°C at room temperature. Could you please help to double check your test conditions? We also double check the SoC temperature of Tinker board 2S at room temperature. Left it at room temperature for an hour later, using the command to read the temperature of SoC only about 45°C. The test conditions as below: - Turn on the power and display the desktop screen by HDMI monitor for an hour later. - The OS is Tinker OS (Debian10) - Heat sink is used. - Case not used. The test results are as below: We also tested Tinker board S R2.0 under the same conditions, and the temperature of SoC read with the command for an hour later was about 52°C, and the test results are as below:
  2. Hi @K.W.JIN Description of the specifications from the website, it seems to work fine. Please also double check that the following requirements are met. 1. 12-19V DC power input. 2. The DC jack (power connector) type of Tinker board edge T is 5.5/2.5mm. 3. The polarity is Center positive. The picture below is item 11 you mentioned. Thank you.
  3. Hi @nottwenox Tinker board 2s uses DC power supply, the DC adapter type and power consumption table are as attached for reference. 1. 12-19V DC power input 2. Connector type : 5.5/2.5 barrel type, the polarity is Center positive Power adapter suggestion: From Amazon https://www.amazon.fr/ASUS-Chargeur-ADP-...B07FFM39D8 From FSP https://www.fspgroupusa.com/ecommerce/nu...bn3-r.html From Japen on-line shop https://www.physical-computing.jp/product/1925
  4. Hi @Excel Tinker board 2 supports 3x USB 3.2 Gen 1 TYPE-A ports and 1x USB3.2 Gen 1 TYPE-C OTG port. The TYPE-A and TYPE-C ports are each in a separate USB 3.2 Gen 1 group. Since the three TYPE-A ports of Tinker Board 2 are implemented by USB HUB. When each TYPE-A port is used individually, each port can support up to 5Gbps; however, when all 3 TYPE-A ports are used simultaneously, they will share 5Gbps of bandwidth. If you have a requirement for two 5Gbps USB ports, it is recommended that you use TYPE-A and TYPE-C to implement your requirement, respectively. Thanks.
  5. Hi @JulianR When pin 5 (pyhsical 18) set as an input port, to avoid leaving the connector in a floating or unknown state when the wires are not connected. This pin will maintain the latest connection voltage, which is a hardware behavior. If you want to be able to restore the original state, it is recommended to add external pull-up (3.3K) or pull-down (100K) resistors to do the default state setting. Thanks.
  6. can you tell me what is the difference between zone0 and zone1? ==>zone0 and zone1 are the temperature of the CPU and GPU, respectively. where are the sensors placed? ==>The sensors are built inside RK3399.
  7. Sorry for the late reply. Even though the TJ of RK3399 is 125oC, we set the protection temperature at 105oC.
