Which board do I need? Answer 3 questions to find the right type
The four board types in one look
Size tip: the 2nd photo on each board shows it to scale next to an Arduino Uno (6.9 x 5.3 cm). Double sided boards have plated holes, so joints are stronger and pads lift less often. Etching copper clad needs ferric chloride, listed in the copper clad section.
About Solderless Breadboards
Solderless breadboards for testing circuits without soldering: 25 and 170 point minis, 400 point half size, 830 and 840 point full size (MB102, GL-12, transparent). Parts and jumper wires push in and pull out, so one board is reused for every project. Breadboard power supply modules and U-shape jumper kits are here too.
