Terminal Block modules for Raspberry Pi Pico come with screw or DIN rail mounting option

if you’d like to use terminal blocks with your Raspberry Pi Pico, or compatible board, instead of soldering wires to the MCU board, HCDC’s Terminal Block Breakout Module may meet your requirements with variants for either screw or DIN rail mounting.


I have not mentioned it in the introduction, but after reading the specifications, it appears (Xuken) HCDC may be based in Taiwan. 🙂 The company explains its Terminal Block Breakout Module for Raspberry Pi Pico is best suited to industrial control, home automation, and other applications that may benefit from terminal blocks.

The breakout module comes with two 20-pin 2.54mm pitch pin header connectors to be soldered to Raspberry Pi Pico, and a 3-pin 2.54mm pin header connector for debugging (SWD). The screw mounting version also includes two 10mm M3 wood screws.

I’ve also noticed “OONO” offers another form factor for Raspberry Pi Pico breakout board with terminal block, again with both screw and DIN rail mounting options.

All four models can be purchased on CZH-LABS Electronics Salon shop for prices ranging from $15.92 to $22.40.
