Thermal Camera works well!

I purchased a thermal imaging camera from Waveshare.com and tried to connect it to UC After communicating with customer service, it was learned that this thermal imaging camera does not natively support Linux or Raspberry Pi and requires self debugging of the software, After continuous efforts, I am very happy to finally obtain imaging on UC [temp_test] [PICTURE1] [PICTURE2] [PICTURE3] Thermal Camera: https://www.waveshare.com/wiki/Thermal_USB_Camera_(C) Tutorial: GitHub - HarryLee-CN/t…

uConsole with CM4 & CM5 - with and without Waveshare board

[1000009712] [1000009717] My current solution for the CM5. I wired a waveshare heatsink and fan to the the spare usb pinout of the sdr board. I also added a switch so i can control when it runs. It brings it back down to 33-35 in about a minute. I had to cut open the back for heat sink clearance.
