P-PC-BB400 BreadBoard - Solderless, 400 point pattern
Solderless (plug-in) breadboard with 400 connection tie-points (i.e. 400 wire insertion holes) and 4 power rails. Solderless breadboards are great for building and testing new circuits because parts can be easily inserted and removed making them completely re-usable. This breadboard has a 300 tie-point IC-circuit area plus four 25 tie-point power rails. The housing is made of white ABS plastic, with a printed legend giving numbers and letters for columns and rows. The internal contacts are phosphor bronze with a plated nickel finish and a peelable adhesive tape backing is provided for attaching it to a surface. Be sure to check out the Zipwire™ jumper wire kits for use with this breadboard.

P-PC-SB404 BreadBoard - Solderable PCB, 400 point pattern
Solderable PC BreadBoard enables you to transfer your circuit and wires from a plug-in breadboard without recutting wires or changing your layout. This breadboard has the same pattern as a standard 400 connection point solderless plug-in breadboard which has a standard 5-hole strip for each IC pin, just like solderless breadboards. However, it has the advantage that soldered joints provide a more reliable long-term connection than solderless contacts.
The board has four power rails like solderless breadboards, plus two bonus rails for power or signals. There are bonus two-hole pads along the centerline allowing DIL (dual in-line) headers to be used as well as a top side silkscreen to position components. Four mounting holes allow your projects to be secured.

P-PC-ST1 StripBoard - Single Sided, Size 1, Uncut
Prototyping circuit board with a standard long strip pattern where tracks run the length of the board. The long tracks are convenient for power and ground rails, and for signal buses. Strips can be cut as needed to make smaller tracks and circuit pads and the board has 0.1" hole spacing for DIP integrated circuits/ headers as well as other parts. Higher quality than traditional stripboard, the holes are drilled, not punched.

P-QLM386N1 Audio Power Amplifier - LM386N-1, Low Voltage
LM386 Low Voltage Audio Power Amplifier The LM386 is a mono low voltage amplifier that can be used in a variety of applications. It can drive loads from 4 Ω to 32 Ω. The gain is internally set to 20 but it can be modified from 20 to 200 by placing a resistor and capacitor between pins 1 and 8. As this is an Op Amp it can be used in different configurations to fit in several applications. The internal gain setting resistor allows the LM386 to be used in a very low part count system. In addition a series resistor can be placed between pins 1 and 5 to modify the gain and frequency response for specific applications. These are found in many small audio amplifiers and even tiny pedal sized guitar amplifiers! There are tons of possibilities for this little Op Amp.
