PT0603 is the smallest (1.6mm × 0.8mm), PT0805 is mid-size (2.0mm × 1.25mm), and PT1206 is the largest (3.2mm × 1.6mm). Choose based on your PCB pad layout and ease of soldering — PT1206 is the easiest to hand-solder, while PT0603 suits fine-pitch automated assembly.\u003c\/p\u003e\n\u003ch4\u003eQ: Are these photoresistors compatible with Arduino and Raspberry Pi projects?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! These SMD photoresistors can be used in Arduino, Raspberry Pi, and other microcontroller-based projects, typically in a voltage divider circuit.
