Overview	Printrboard, a development board, originally based on sanguinololu, is one of the lasted versions of control board for 3D printer. Compared with sanguinololu, what makes Printrboard special is the onchip USB, removing the need for the FTDI UART (USBtoserial) IC. Onchip USB means dramatically faster firmware upload times and communication. What’s more, the Printrboard is equipped with a micro SD slot, which means you can paste the print file to the SD card to implement offline printing. Printrboard is highly integrated, all our Printrboard has been tested rigorously and preassembled before shipping, including the four integrated Allegro A4982 Stepper Drivers (no Pololus needed), which is on the one hand a good thing for a lay man of electronics, but on another hand, it will be difficult for them to repair by themselves if there is some damage. On the whole, the Printrboard is of high capacity-price ratio and friendly to use.
