實驗器材和晶片的介紹 - Solderless Breadboard
Introduction of Solderless Breadboard
■ Solderless Bredboard is a convenient kit for lay outing circuits without
any soldering (焊接) work. It is very useful for circuit test and
modification during practical training.
■ Components in lab can be reused with breadboard.
■ Normally, component’s pins are inserted into holes on breadboard.
Every five holes are connected together by a brass stripe under plastic
cover. One of holes is connected to component’s pin and the other
holes are for circuit connection with jumpers.
