This is the larger 830 tie point breadboard. The back side has an adhesive pad on it, to stick the breadboard on any surface. The 2 power lanes are detachable, and all parts (main panel and power lanes) are tongued and grooved. This way, you can build your own supersized breadboard (see example pictures). Each board is 165 x 55 mm x 8.5 mm, and can accept solid patch wires with a diameter of 0.3 to 0.8 mm diameter (AWG 20-29). The maximum current per lane must not exceed 5A, the insulation voltage between the lanes is 300V, and mast not be exceeded as well. Arduino Nano V3 and CANADUINO breadboard Buddy, as shown in the picture, are not included!
