Red & White PCB-mounting RCA sockets
Traditionally, the stereo input sockets for an audio device are white (left) & red (right). But sourcing white sockets is hard, so we're offering this set.
These sockets can be used with projects such as the CLASSiC DAC. While they aren't an exact fit for the footprint on that PCB, they will fit with a small amount of coaxing.

SMD components for the 100dB Stereo Audio Level Meter/VU Meter
A set of all the SMDs you need to build the Stereo Audio Level Meter, except for the programmed microcontroller and LEDs - both of which are available separately (see associated items).
See the parts list link below for details on what is included.
You will need to purchase the PCB separately. We can also supply the optional clear acrylic case pieces. The three through-hole connectors can be purchased from Jaycar, Altronics or just about any other electronics retailer. The pushbutton switches (S1 and S2) are from Jaycar.
