Breadboard Flexible Breadboard Jumper Cable Wires for Arduino in Pakistan

board four weeks with four screws holes, hole diameter 3.1mm, easy to install and fixed relay of high quality loose music relays SPDT. A common terminal, a normally open, one normally closed terminal optocoupler isolation, good anti-jamming low pull, high release. Energisation status indicator light, release status LED is off VCC of system power, JD_VCC relay power. You can plug in jumpers

Used in conjunction with the Duemilanove ProtoShield prototype expansion board, the circuit is used to build a prototype, can be directly soldered components on the board, you can also connect the above mini breadboard circuit. Bread board and circuit board via double-sided adhesive connections, sold bread board and the circuit board are separated. ProtoShield prototype expansion board with two buttons and two LED circuit can be used directly, all of the pins and the power leads are very fit and build circuit prototyping with Ardui-no.
