Educational models and laws in most countries have promoted the inclusion of people with disabilities in the school system. In the case of Ecuador, the development of teaching and learning methods and tools for people with visual impairment is a priority. However, teachers lack didactic tools to facilitate the teaching-learning process, particularly with regard to reading and writing for people with severe visual impairment. Therefore, the aim of the research was to develop a didactic module that can include improvements and strategies for teaching people with visual impairment with state-of-the-art technologies. Methodologically, the research consists of three phases; the first, design using SolidWorks software, the second, assembly, through elements printed under 3D technology and configured in a free and friendly programming language called RANMAN and the third, validation of the module. This last phase sought to evaluate the degree of acceptance of the device by teachers and students with visual disabilities. The results show that the didactic module optimizes the learning process of reading-writing skills in children with total disability, by merging Braille language with Raspberry technology for the design of the device that reduces the cost. In addition, the system has been accepted by teachers and students included in the pilot test.
