It is aimed at makers and engineers who need a robust, pluggable way to wire a Pi to field devices. The single biggest reason to buy is the combination of a 3.81mm pitch screw terminal array and a DIN rail carrier that turns a Raspberry Pi into a neat, serviceable control node without trial-and-error wiring.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN rail mount carrier:\u003c\/strong\u003e The fireproof nylon carrier supports common 35mm, 32mm and 15mm rails for secure, professional mounting in control cabinets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew terminal interface:\u003c\/strong\u003e High quality 3.81mm pitch screw terminals accept 26-16AWG wire and simplify field wiring with a 5mm strip length requirement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRaspberry Pi compatibility:\u003c\/strong\u003e Designed to plug into Raspberry Pi A+, 3A+, B+, 2B, 3B, 3B+, 4B, Zero and Zero-W with CN3\/CN4 1:1 connectivity for direct I\/O access.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtension connector:\u003c\/strong\u003e CN4 provides a 40-pin extension path so the board can connect to other devices using an FRC 40-pin cable for distributed wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable PCB construction:\u003c\/strong\u003e FR-4 fiber glass PCB with dual copper layers gives a solid, reliable base for repeated installs and wiring changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact footprint:\u003c\/strong\u003e The module and PCB dimensions are sized to fit in racks and panels without excessive space penalties.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe module is best for makers, hobbyists and small automation projects where a Raspberry Pi is being used as a controller and needs tidy, serviceable field wiring.
