About the Cross point exp brd mini smd PCB

Cross point exp brd mini smd is an open source RP2040/RP2350 PCB design by damercer, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 127 × 100.3 mm, with 51 components from 23 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the CH446Q, MCP4822 and MCP6004. By type, the board carries 12 resistors, 8 ICs, 8 connectors, 8 capacitors, 3 jumpers and 1 test point.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

A Software Configurable Solderless Breadboard

The goal is to evaluate the educational benefits and potential drawbacks of these software-configured hardware systems compared to traditional manual wiring. By doing so, it addresses the need for balancing hands-on skills with error minimization and conceptual understanding in electrical engineering education. # Analog switch matrix cross point experiment breadboard. # Production PCB (Red3 version, instructions for ordering boards can be found in PCB Projects folder)
