## Description

This one's going out to all the makers and designers who use DIN railing in their builds. This adapter plate is perfect for simplifying complex wiring. You connect an Arduino Mega or [Grand Central M4 Express](https://core-electronics.com.au/search/?q=grand%20central) to this breakout PCB, which can be DIN rail-mounted. All wires are broken out into terminal blocks, so you can connect and power your sensors, displays, microcontrollers, etc.

**No soldering required!** Place the microcontroller face-down onto the headers, unscrew the terminal blocks, and slide in your stranded or solid-core wire.

**Note**: DIN Rail and microcontroller are not included.
