This is a 40-pin (2 x 20 row) header with a 0.1″ (2.54mm) pitch! You can solder this onto a Raspberry Pi Zero/W. They’re super special gold-plated ones for excellent conductivity and they won’t oxidize!

Breakaway headers are the duct tape of electronics. They’re great for connecting things together, soldering to perf-boards, and fit into any breakout or breadboard!

These 40-pin long headers, 0.1″ pitch, can be stacked next to each other on a 0.1″ grid and broken apart easily with pliers or diagonal cutters.
