GLOBAL SPECIALTIES PB-203A 原型开发板
The is a durable powered breadboard capable of being used to design a multitude of analog, digital, logic and microcomputer circuits. The PB-203A"s on-board power supply eliminates the need for an external supply, adding more versatility to circuit design and experiments, as well as saving valuable bench space by eliminating the need for an external prototyping power supply. Due to its ample sized breadboarding area, the PB-203A is ideally suited for virtually any type of breadboarding circuitry, from TTL, CMOS and ECL, to op-amps, audio, comparators, video amps, micro_processor components, phase locks and more.Features
