This pcb is created to make a spider robot which modifies it by adding an OLED screen, for those who want to use this pcb it is made to measure for all the components and if they want to do the same project as me I will also leave the arduino code nano so that they can make their own, it is also controlled by an application that unfortunately I cannot upload, but what I will leave will be the schematic and also for those who know how to use my app inventor, I created my application there so that the code shows what letter use to move the robot I hope you do well in your project.Also if you pay with pcbway you will only pay $5 with 10 plates! with that pcb so take advantage of the offer.
