These are 1 inch square single copper layer non-plated through hole boards. Actually this little board can never finish any complete electronic system, however, I am pretty sure you often have a requirement of building a simple circuitry in front of or after your large system or instrument, or in the middle of its signal processing. For example you want a signal buffer, you want a impedance maching circuit, you want a pre-amplifier, you want a filter, you want a different voltage regulator, you want a simple logic, or you want a power output. These little boards give you convenient solution to solve these problems in a few minutes.
