Recently, I have tried Pixhawk2.1 and found that even if I just plug in usb port to power the board, the cube temperature is quite high (feeling when I touched it compared to Pixhawk1 and verified with thermometer gun to 37 DegC). I successfully tested Pixhawk2 with my quadplane with just short hover flight. There was no problem regarding the board except the temperature issue I mentioned.
I have tried to search for many forum with no luck. Someone said it is set to 60C. However, after I look at default parameter BRD_IMU_TARGTEMP, the default is -1 (disable).
I’m not sure shall I enable it to maintain 60C ?
I’m quite worried since I live in hot tropical country. The ambient temperature is quite high up to >30C. For longer full flight not sure if it will function properly or not.
Not sure which level of temperature should I set or disable is already a good idea ?
