{"title":"Universal Pre-Punched Experimenters Board - Large","handle":"universal-pre-punched-experimenters-board-large","url":"/products/universal-pre-punched-experimenters-board-large","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.\n\nThe 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.\n\nKey Features\n\n\nDoughnut Pad Layout – Isolated pads with easy bridge soldering between neighbours\n\n1608 Holes – Plenty of space for complex circuit layouts\n\nEdge Connector Fingers – 3.6 mm pitch on opposite ends for card edge or external connections\n\nAlphanumeric Grid – Printed on the non-solder side for easy component identification\n\n\nSpecifications\n\n\nDimensions: 210 × 78 mm\n\nBoard Type: Doughnut pad\n\nHole Spacing: 2.5 mm\n\nNumber of Holes: 1608\n\nEdge Pitch: 3.6 mm\n\n\nIdeal For\n\nCircuit prototyping and experimentation\nPermanent soldered project builds\nEducational electronics projects\n","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":10006,"title":"Default Title","sku":"TB-HP9554","price":11.32,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":23,"option1":"Default Title"}]}
