#104195 - source of heat Responding to: ???'s previous message |
Air circulating is not very well , but the thing is not in a steady place (it is placed in a vehicle)so some wind exists.
By mentioning the Regulator you just got me thinking about the Regulator which is a LM7805K without a Heatsink feeding by the Vehicles battery (12-14.5v) which could dissipate too much heat. This regulator is placed nearby the AT89S52 DIP so MCU could get heated up from here. Thanks , Farshid |
