<div dir="ltr">Yes, it is rather hot inside the electronic panel volume. 75 degrees C is the temperature of the FPGA chip. The temperature of the air inside is around 40-45 C. </div>

Do you really mean 75 degrees C ? Seems pretty hot in RICH-2. </div>

I suspect you meant to say 75degrees F ? </div>
