I'm making some tests to see if my controller works when warm.
And I don't have any problems with the AVR's, and my display works fine to about the spec of 70 C.
But My bluetooth module bluegiga BLE121 seems to have problems at that temp as well and it should work up to 85C!
But it's hard for me to check if it's the module or something around it.
Any with some experience?
