The humble electronics breadboard is where projects are born, and sometimes we need more than one to realise our dreams. For times like this the Overboard Electronics Reference Breadboard , a crowd-funded project by Ian Dunn at Bolt Industries could be the solution.

The Overboard Electronics Reference Breadboard and Power Supply has space for four full-size breadboards, interlocked in the center of the FR4-PCB. With this number of breadboards, we can build incredibly complex projects using our favorite microcontroller, the Raspberry Pi Pico W , or we can solder up another Z80-based microcomputer. But, this isn't just a large PCB with lots of breadboards, it has a couple of cool features.

At the top of the PCB is a variable DC power supply which when fed between 6 and 24 Volts, can step-down to the exact required voltage thanks to a potentiometer. A built-in 500mA self-resetting fuse will take the hit should you encounter a power issue. The power supply connects to the rails of a breadboard , and from there, it can be connected to other rails using jumper wires.

Around the perimeter of the board are a series of electronics reference tables and pinouts for popular boards such as the Raspberry Pi 4, Raspberry Pi Pico and the Arduino Nano. There is even a schematic for the venerable 555 timer, resistor color codes , and Ohms Law.

This level of quick reference is sublime. We've lost count of the number of times that we've forgotten the pinout of a 555 and mistaken a 1K resistor for a 10K .

Ian Dunn and Bolt Industries are no strangers to these pages. Previously, Dunn created Pico 87 , an 87-key mechanical keyboard that uses a Raspberry Pi Pico as its controller.

Starting from $25 for the basic pledge (no breadboard), there is also an option for a $45 pledge for the full kit. Remember that crowdfunding a project is not a guarantee of receiving a finished product. Backing a crowdfunded project is akin to an investment; you believe in the project and want it to succeed. You are not purchasing a retail product.
