70mm × 50mm Protoboard (aka Perfboard)

Overview

A standard FR-4 perfboard for through-hole prototyping. Each pad is electrically isolated, so you wire point-to-point as needed - giving you full layout freedom compared to strip/veroboard. The 2.54mm (0.1") hole pitch is the standard for DIP ICs, pin headers, and most common through-hole components, so everything fits without modification.

Holes are labelled A-R across and 1-24 down or A-X across and 1-18 down depending on the batch. Four corner mounting holes suit standard M3 standoffs. Available in green or blue soldermask.
