Printshield v1.0 for Arduino printbots [Git repo]

thingiverse

Introducing a simplified circuit board for creating Arduino-based Printbots! This easy-to-make, one-sided board features two light sensors (LDR), an ultrasonic distance sensor, two buttons, four LEDs, and four servo-motor connectors. Compatible with CNY70 boards, this board has a 1000uF 6.3V cap between +5V and ground, LED resistors at 330ohm, and LDR resistors at 33kohm. Learn how to create the PCB using either YouTube or Instructables tutorials. The connection diagram has also been provided for your convenience. Modifications include powering Arduino with at least 9V, adding a capacitor on the 5V line when using servomotors, and including a diode in series with the servo power line to minimize voltage peaks affecting the 5V line. Compatible with Arduino Shield library and Monolito library. Designed with Kicad. PCB files can be found on GitHub.
