A system design for a digital electronic sign board comprises a main circuit module, an adapter module and a computer module; wherein the adapter module is fixed between the main circuit module and the computer module. The main circuit module and the adapter module are fixed in the digital electronic sign board. The computer module is externally inserted into the digital electronic sign board. Therefore the computer module and the main circuit module are electrically connected through the adapter module. The system design of the present invention removable and attached the computer module with the main circuit module. As a result, when a maintenance worker needs to perform maintenance on the computer module, he or she can conveniently pull out the computer module from the digital electronic sign board and insert the computer module back to the digital electronic sign board after maintenance is done so as to improve the efficiency and quality of maintenance.
