+alt: A 3D render of a simple PCB.
+---
+I made my first PCB!
+
+I've had a longstanding ambition to get a PCB manufacured but I've always put it off. Lately I had a need for a little adapter board to break out these 1.27mm spaced pins to 2.54mm pins that would fit into a breadboard. Feeling like it was a simple enough board I finally decided to fire up KiCad and give it a go.

+
+
+
+The layout.

+
+
+The 3D render!
+
+
+
+The boards haven't arrived yet so no photos of the final result.
