120: Screw Terminal Breakout Board — revised

I just got 2 Electronics-Salon breakout boards. They are designed to fit the full sized Pi boards but I plan to use them with Pi Zero-Ws, as in this image:

Pi Zero underneath

My Pi Z's male header plugs directly into the underside of the breakout:

The standoff bolts don't fit a Zero so I removed 2 and left the others to support the breakout. There is just enough room under the breakout to stick on a heat sink. I think the Zeros will be ok but wonder about heat with a Pi B+.

I haven't hooked one up yet but I like 3 things: the screw-down connectors, that they are labeled and they are separated enough for my clumsy fingers. What I don't like: $17US at Amazon.

Added later: I wired one up. Oddly, I got it right (15 wires) first time! Pin numbering distinctly odd. BCM labeling but not like the Pi numbers. Still pretty good.
