A Jumperless Breadboard with Kevin Cappuccio
Kevin Cappuccio, founder of Jumperless, discusses the V5 iteration of his jumperless breadboard, an interactive prototyping platform featuring an RP2350 microcontroller and a dense matrix of CH446Q analog crossbar switches. He explains the hardware architecture, including the use of LM2660MX charge pumps to drive the switches with ±9V, custom spring clips, and 445 RGB LEDs for visual feedback. The conversation covers the routing algorithm, which minimizes resistance by stacking parallel paths, and the probe's ability to detect position and signal type through a single jack. Cappuccio highlights the product's educational value, open-source firmware, and the community-driven development via Discord and GitHub.
