For the development of learning in low-level computing, by the hardware, the teachers who teach the Laboratory Organization and Computer Architecture (LOAC) subject, of Course of Computer Science from Federal University of Campina Grande (UFCG), use an apparatus relatively high cost. These are the boards from Altera© DEO2, which are composed of a programmable processor (FPGA - Field-programmable Gate Array), SDRAM and EEPROM memories, multiple inputs and data output including switches, cable entry Ethernet, VGA, audio, USB, an LCD display among others. The major problem lies in the storage of these boards, plus maintenance and parts purchasing enough for a whole class. The cost becomes unviable. This work aimed to develop a simple plate, low production cost and high durability
