Highest quality. Designs are flawless and very useful. The skinny ones have 4 wiring attachment pads, but are side enough to drill if desired. The number of pads lend the boards as exceptional for I2C prototyping. All boards are easily cut to size desired. When cut in half, they have attachment pads on one end for each board. All boards have the pads. The boards are strong and appear to be FRx fiberglass.
