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.

Applications
- Voltage controllable range – 15 octaves
- Accurate exponential frequency scale
- High input impedance buffers
- Wide transconductance range
- Low input offset voltage
- Low control voltage feedthrough - 45 dB typical
Applications
- For electronic music
