Simulink Electrical Circuit(SEC) Model 622.36 This is the serial number shown on this image. It’s the number that we measured the resistor on. You don’t have to cut it. It just needs the address of the circuit board. Here is a schematic diagram of the Arduino board. I used the latest firmware (1.26) if you want to use it. http://www.aupf.com/forum/index.php…p_program_name
