Breadboard - Solderable PCB, 3.75” x 1.85”, Mounting Holes
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.

StripBoard - Single Sided, 6.30” x 3.94”
ST3U StripBoard is a prototyping circuit board with a standard long strip pattern. 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. It has 0.1" hole spacing for DIP integrated circuits and headers and other parts. It has higher quality than traditional stripboard. The holes are drilled, not punched. The base material is high-quality FR4 glass epoxy board. It has better stability and moisture resistance than boards using phenolic or SRBP (synthetic resin bonded paper), which can warp with exposure to humidity. Features
  • Standard stripboard pattern, with tracks running the length of the board.
  • Single-sided high-quality FR4 glass-epoxy circuit board.
  • 1oz/ft2 copper with an anti-tarnish coating for easy soldering.

PCB - LED Driver, for Pedals and Synths
This small PCB is a simple way to add an indicator light that pulses to the rate of LFOs and clocks used in pedals, synthesizers, and other equipment. Simply connect the positive supply voltage to V+, ground to GND, and the output of a positive signal (0 to V+) such as an LFO or clock to the IN pad. The trimmer can adjust how the LED reacts to the signal. Fully clockwise it will simply pulse on and off when paired with a strong signal. If the signal is a sine, triangle, or any other non-pulse type signal, adjusting the trimmer counter clockwise can dial in settings that follow the shape of the waveform, brightening and dimming with the changing voltage. For certain dual op-amp LFOs in effect pedals, the signal may not go low enough to turn the LED fully off.
