With so many smaller and more capable microcontroller boards on the market it’s now fairly safe to say that the classic Arduino footprint and form factor is rather outdated. That’s not to say that there’s no fight left in the old contender though, and to prove it here’s a new platform in the familiar style set by the venerable Atmel-based board. [Eduardo Corpeño]’s Brainfuino is an Arduino competitor that runs everyone’s favourite esoteric programming language, Brainf*ck. (Keeping it SFW, folks.)
And in case you mistake it for a Brainf*ck emulator on a PCB then stand ready to be corrected, for this board runs the language natively in a Brainf*ck softcore on a Lattice MachXO2 FPGA. This is the real deal, on which only a true genius or masochist would dare to code.
The board itself is very neatly executed with a graphical style that presents more than a nod to the original Arduino. On this board is the FPGA, 256 kB ROM and 138 kB RAM, an STM32 to provide a USB serial port and an analogue input, and a level shifter to provide Arduino-style 5 V logic on the pins. We can see it’ll provide hours of fun to anyone interested in learning Brainf*ck, but besides that it has potential as an Arduino-shaped FPGA board. We like the joke, we like the graphical and engineering design, but underneath that lies quite the technical achievement.
Brainf*ck has made it to Hackaday before, not least in this jaw-dropping relay computer.
