Cytron's Arduino Proto Shield offers maximum prototyping area within the standard Arduino UNO dimensions and on-board extras! This shield comes fully assembled and features 4 rows of stackable headers and onboard SMD components - an LED, push-button and resistor soldered on the well-labelled PCB. Great for making more permanent versions of your own project, or just for creating your very own shield! Features * Standard 0.1” X 0.1” prototyping area * Stackable headers * Reset button * One LED for use as power or output indicator * Every pin is extended out to two sides of the headers * GND and +5V rails * 4 screw holes for easy mounting on Arduino * Pre-assembled - no soldering required (apart from adding your own components of course!) * Dimensions: 68.58mm x 58.42mm Note: The Cytron Protoshield has been revised to be UNO R3 and Leonardo compatible (including the Maker UNO. Cytron have also prepared the pads for ISP. https://elecena.pl/product/22720704/cytron-prototyping-shield-for-arduino 2023-03-07 https://elecena.pl/product/22720704/cytron-prototyping-shield-for-arduino 2023-12-27 https://elecena.pl/product/22720704/cytron-prototyping-shield-for-arduino 2024-09-19 https://elecena.pl/product/22720704/cytron-prototyping-shield-for-arduino 2024-11-29 https://elecena.pl/product/22720704/cytron-prototyping-shield-for-arduino 2024-11-30 https://elecena.pl/product/22720704/cytron-prototyping-shield-for-arduino 2025-11-28 https://elecena.pl/product/22720704/cytron-prototyping-shield-for-arduino 2025-11-29 https://elecena.pl/product/22720704/cytron-prototyping-shield-for-arduino 2026-04-08
