SC115, v1.0, Description

Signal breakout module PCB to aid prototyping of RC2014 modules on solderless breadboards.

SC115 v1.0 Assembled

This PCB is designed as an aid to prototyping RC2014 modules on solderless breadboards. It allows RC2014 bus signals to be easily connected to a breadboard with Dupont cables.

The board includes flexible I/O address decoding, so you don’t need to include such circuitry on every prototype. The decoding has jumpers to configure the start address and range. This includes allowing partial decoding with shadow addresses.

The address decoding circuit provides an I/O enable signal (/IOEN) and also separate read and write versions (/IORD and /IOWR). This range of enable signals allows easy interfacing to most I/O devices.


  • Easy access to RC2014 bus signals
  • Flexible address decoding generates /IOWR, /IORD and /IOEN
  • Connection to solderless breadboards with Dupont cables

Here’s an example application. The module is breaking out signals to a couple of breadboards. One breadboard contains a simple digital input port and the other contains a simple digital output port.
