This research proposes the use of AFE (ADS1299), its manufacturer exposes some surface mounting parameters that served as the basis for the design of the PCB in Corel DRAW. The bibliographic review opens a path regarding the application of the field of study, as can be seen in this review of the state of the art prototypes have been developed in which the ADS1299 is projected as a fundamental piece for the capture of biomedical signals and depending on There are several cards used as a teacher that allow communication and visualization. A PCB with adequate size is obtained, using surface materials that provide less noise to the system, whose economic value is accessible. The reverse engineering process applied to the master-slave cards of the Texas Intruments, served as a significant guide for the hardware construction parameters that had not been taken into account, as a result of the selection of the arduino DUE (master) of the already developed plate. The test signals allowed a clear operation of the system as a whole, subsequently the capture of biomedical signals was performed by evaluating them through Matlab software, validating the information with the Texas instruments kit; results with equal signals in 98% are examined, and in another validation with the “concentration level determination” software prepared by the students of the University of Ibagué; I present optimal biomedical signals in amplitude, frequency and with a minimum level of noise, which checked the operation of this program.
