This blog post describes the details about the hardware, more specifically the PCB that I have developed for the display component of the new Printrbot Simple 2016. As we believe in Open Source we have published everything under the MIT license. Have a look at the code respository, too.
To give you some context why we have chosen these components please first read my Behind the Scenes report that describes the process of selecting the right components for our purpose.
Let’s have a look at the Block Diagram of the Simple 2016 and how various components are connected. First we have a very clever power management that delivers enough current for all the motors and PCBs but also does that secure and with great efficiency. Next there is the Printrhub, which is the display component of the printer. The hub also controls the Printrboard and the ESP module to communicate with the Printrbot cloud that holds all the projects, materials and settings of the user. Last but not least there is the printer itself, powered by the g2 Printrboard with advanced motor handling features and advanced algorithms for great prints.
