## Description

A versatile prototyping board with a doughnut-pad layout for building electronic circuits. Each pad is separated from its neighbours by approximately 0.5 mm, providing electrical isolation while making it easy to bridge solder across pads to create interconnections. The board features edge connector fingers on opposite ends with a 3.6 mm pitch, allowing connection to card edge connectors or external wiring. The non-solder side includes an alphanumeric grid for component identification and layout planning. Key Features Doughnut Pad Layout – Isolated pads with easy bridge soldering between neighbours 1608 Holes – Plenty of space for complex circuit layouts Edge Connector Fingers – 3.6 mm pitch on opposite ends for card edge or external connections Alphanumeric Grid – Printed on the non-solder side for easy component identification Specifications Dimensions: 210 × 78 mm Board Type: Doughnut pad Hole Spacing: 2.5 mm Number of Holes: 1608 Edge Pitch: 3.6 mm Ideal For Circuit prototyping and experimentation Permanent soldered project builds Educational electronics projects
