Rajesh used a flexible PCB substrate to achieve this, rather than the traditional fiberglass.
The Flexduino, however, takes things to another level by functioning as a full-fledged development board.
At its core, the Flexduino is essentially a clone of the classicArduino Unodev board.
This change allowed him to eliminate the rigid DIP package that would have restricted the board’s flexibility.
It’s also extremely thin, measuring just 1mm thick.
As a fun touch, the developer even had ‘Flexduino’ printed on the board.
Rajesh shared a video demonstrating the board in action.
It powered an RGB LED and ran sample code without any issues.
Of course, while the PCB itself can bend, the actual electronic components remain rigid.
Combining all of these innovations could lead to a truly flexible, unbreakable electronic gear.
For now, however, the Flexduino serves as a cool proof-of-concept for flexible PCB design.
The entire process is documented on Rajesh’s YouTube channel for other makers to follow.
