I design a circuit of Modbus and GSM with two different regulators.
Modbus need voltage >4.8 and GSM need 4 volt so i used 7805 (1Amp) with Max485 and atmega8 converter and LM2596 (3Amps) Adjustable regulator to power up GSM board . and input supply is 12V/2A adapter. when i use this circuit to read data from inverter and send data using http request.
my 7805 goes heat up but circuit working properly . please suggest me what change should i make ??
