The screw terminal HAT for Raspberry Pi works with all Raspberry Pi models.
Screw terminals provide a more secure way of connecting wires to products that may be exposed to vibrations and shocks.
SeeedStudio has come up with another product with screw terminals designed for Raspberry Pi boards, but more geared towards education as the company’s “GPIO screw terminal HAT for Raspberry Pi” exposes all I/Os from the 40-pin expansion headers and adds an LED to each pin.
That means you don’t need to search for “Raspberry Pi pinout diagram” on the web or reach out for a printout each time you plan to wire your project as the main function of each pin is clearly marked on each screw terminal.
It’s an easy way to teach about GPIO since the LED will be turned on and off according to the pin level, or you could even use it for debugging using those user LEDs. That’s all there is to it.
The screw terminal HAT for Raspberry Pi works with all relatively recent versions of the popular SBC, namely Raspberry Pi 4 Model B, Raspberry Pi 3 Model B/B+, Raspberry Pi Zero (W). Raspberry Pi 2 Model B, and Raspberry Pi Model B+.
The HAT ships with four M2.5 copper stands, four M2.5 screws and nuts, a screwdriver, and a GPIO pinout tape.
