Get perfect holes in printed PCB boards with this DIY CNC-base drill press attachment. It uses a Teensy 3.2 (which is like an Arduino on steroids) with a 2.8" TFT display, Nema 17 steppers with A4988 drivers and a 28BYJ-48 stepper with a ULN2803APG driver. Code reads a CSV file of x-y hole data and optimizes path for reduced drilling time in your PCB boards.
