In summary, the automatic programming system of an embodiment of the present invention can control the track switching unit to be located at the first position or the second position by the control module. When the track switching unit is at the first position, the circuit board can pass or be located on the first switching track, and the control module can determine whether to send the circuit board to the burning unit for burning or to make the circuit board skip the burner for downloading One process. The control module can control the track switch unit to move to the second position, so that the first switch track moves toward the burning unit, and the circuit board can be switched to pass through the second switch track. When the track switch unit is at the second position, the burning unit can burn or test the circuit board, and other circuit boards can pass through the second switch track, and can skip the burner that is burning. Therefore, the automatic programming system can automatically carry out the transportation, programming and testing of the circuit board, and it does not need to manually carry the circuit board, and it does not need to manually start or end the programming process for the circuit board. In this way, it is possible to avoid artificially hitting the circuit board by mistake, and also to avoid the occurrence of unexpected situations caused by personal physical or psychological conditions.
