This is a set of 4 1-bit full adder boards that can be easily used on breadboard. They come as an assembled single PCB that is snapped apart. The included headers can be soldered onto the PCBs or wires can be soldered directly to the PCBs. Using multiple units on a breadboard, it is easy to demonstrate and analyze a basic 4-bit or 8-bit binary adder with ripple carry function. Each input on the board, A, B, and Carry In, as well as the outputs Sum and Carry Out, have current limited LEDs, so it is easy to visualize functionality. Additional test points on the PCB are provided for in-depth analysis.
The design is implement based on the most popular educational block diagram for a 1-bit full adder which consists of
The design uses 7400 LVC parts that work from +1.65V to +5.5V, however the LEDs are tuned to operate at +3.3V to +5.5V. Design files are available under CC-BY-NC 4.0 on hackaday.io via the "Documentation" link. A video is available of hand assembly of a prototype PCB:
