Screw terminals provide a more secure way of connecting wires to products that may be exposed to vibrations and shocks, and in the past, we’ve seen Pi-oT MKR module enclosure that routes Raspberry Pi GPIO’s to screw terminals, and also happens to include a breadboard area. 52Pi 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 [...]
