Hi,
Actually I was working on a RF simplex communication using a transmitter and receiver modules. On the receiver side the microcontroller gets heated up. I am not able to troubleshoot it. So please help....
Not enough information... Is voltage compatible for instance MCU is poered with 5V but RF receiver can accept 3.3 or 4.5V. Other issue may be a mistake on the PCB. And of cource heating may occur because of failure in receiver module.
I am sorry for the incomplete info.... my receiver module works on 5V as told to me by the seller.... by the way what else info. do you need to trouble shoot.
When I switch on the power then then voltage across my MCU becomes 1V and across receiver it becomes 2.6 to 2.7V. The LCD is also giving 2.7 V across it. I dont how are these voltages distributing.
Anyways the transmitter side doesnot get heated up and the voltages across every component is alright.
there are 3 pins for GND on receiver. Is it necessary to connect all the pins to GND(they are interconnected)???
