Description
Breadboard expander designed for 55x85 mm breadboards. Designed to be modular, and horizontally expandable to slotting them together in a line.
Provides one raw buffer, two inverting summing amps, two non-inverting amps, 5 generic eurorack interface sockets, 4 LEDs, and an additional signal generator or slew rate limiter, which is configurable by jumpers.
The intent is for it to be a board you order a set of 5 of, and configure each board for a specific purpose, then use them together for prototyping.
Requires an external power source with at least +12, -12 and GND. +5 is optional.
