High Boy isn’t just a tool it’s a truly multifunctional pentest gadget built for real-world use. It brings together Wi-Fi, Bluetooth, RF, NFC, infrared, and more, all in one compact, practical, and powerful device.
Inspired by the spirit of the Flipper Zero but with a 100% Brazilian soul, High Boy was created to push things further: it’s open source, open hardware, and fully powered by the ESP32-S3 built for makers, hackers, and anyone who loves to experiment.
Whether you’re an ethical hacker, a maker, a security researcher, an engineer, a tech enthusiast, or just someone who loves to tinker, High Boy becomes your everyday pocket companion.
And he’s not alone: Octobit, our mascot, pops in with tips, fun moments, and a friendly personality that adds charm to the whole experience.
High Boy is more than a device it represents a new phase of hardware hacking in Brazil.
A symbol of national creativity, a growing community, and the drive to put Brazilian open technology on the m
First of all, we want to express our immense gratitude! Thanks to your support, we smashed our funding goal in just 10 minutes and have already raised over $140k! It is amazing to see this community so active, interactive, and helpful.
We have been paying close attention to all your feedback and requests. After analyzing everything, we are excited to announce a major upgrade: High Boy will officially support 5GHz Wi-Fi!
Yes, it will feature native dual-band connectivity (2.4 GHz and 5 GHz). But that’s not all—we are implementing a Dual MCU architecture. It will combine the power of the ESP32-S3 and the ESP32-C5 working together to deliver maximum performance.
Thank you all for making this possible. Together, we are creating something truly amazing!
We’ve come a long way. What started as a simple idea has evolved into a real, fully functional project and in just a few months, we made incredible progress. Today, we stand with a solid prototype and a clear vision. And yes, we made it all the way to Kickstarter.
We want to thank the entire community for the motivation, support, and energy that helped us reach this moment.
To be honest, we took a while to share updates here, but I promise I’ll catch you up quickly now.
Let’s start with the first PCB ever made for the High Boy. We spent quite some time studying the layout thinking about component placement, functional blocks, and the overall area for each section. I sketched a few drafts with what I thought were “compact” dimensions. Eventually, we finalized the schematic and sent it off to get our first prototype made.
Well… it came back — and we ran into quite a few issues. Not to mention the size — it ended up looking more like a Samsung S20 😅. But that’s okay, it’s all part of the journey.
The important thing is that we learned a lot. We carefully marked every issue and took detailed notes so we can improve everything in the next revision.
While we were brainstorming the High Boy thinking about everything from the interface to the features and design a question popped up: "What about a mascot?!"
At first, we hadn’t even thought about it, but then the idea hit us: If High Boy were an animal, what would it be?
And the answer came instantly: an octopus! 🐙
But why an octopus?
Simple: it has multiple tentacles, each one doing something different just like the High Boy’s multi-functionality.
So it was settled: the octopus would be our adventure partner!
Ok, but... what about the name?
After throwing around a bunch of crazy ideas, we finally landed on Octobit or just Bit, for the close friends.
(By the way, there’s a hidden pun in there: an octopus has 8 tentacles, and 8 bits make 1 byte. Get it? 😎)
After that, came the hardest part: bringing our little buddy to life with a design.
There were a lot of attempts, a lot of different versions as you can see! until we finally landed on the current look.
Of course, Bit might still evolve over time, but for now, he’s just the way we imagined:
a buddy to tag along on our hacking journey, always ready to lend a helping tentacle.
High Boy started in a pretty simple way: out of pure curiosity. A lot of people are familiar with hardware hacking devices, especially the legendary Flipper Zero. But as many know, in some countries especially in Brazil the Flipper has become restricted.
So the question came up: "Why not make my own?"
That's how it all began, as a personal project. If it were just for me, it would already be done: full of improvised soldering, lots of PTH components, and of course, no case something really rough, just for those who understand.
But as the ideas and project photos started to spread around, a lot of people started asking: "Why don't you make it for production?" And that's when the story changed. Since the goal is now to reach a broader audience, we're putting real effort into creating something truly well-made with professional finishing, thoughtful design, and a level of quality we would be proud to bring to the market.
