Description: This is a very simple but handy, 2" square, double sided perf board. Standard 0.1" spacing with a 4-40 (3mm) holes for mounting. Great for quickly prototyping stackable circuits.
Based on 1 ratings:
One side has isolated square pads and the other has a copper pour with isolated circular pads. The holes are through-plated. The square pads are easy to solder to adjacent pads with the “vulcan solder meld” method. The copper pour makes it easy to route your ground points around the circuit.
Overall the quality is excellent. a few pads came off, but they were soldered and unsoldered a bunch of times.
