High Boy: For hackers, makers, and the curious.

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.

Meet High Boy, a next-gen hardware hacking device that merges power, versatility, and portability in one compact tool.

Open-source, pocket-sized, and built for hackers, makers, and learners alike.

High Boy isn’t just another gadget; it’s a complete platform for creativity, electronics, and security.

Developed in Brazil, it combines the power of multiple technologies in a compact, expandable, and educational device.

High Boy: Born from restriction, built for open-source freedom.

Every day, tech enthusiasts, students, and curious minds like us encounter an invisible world of signals. A world that controls everything from our garages to the Wi-Fi networks that connect us. Curiosity is core to human nature. 

Then, one day, that curiosity was blocked. Powerful learning tools began to be restricted and banned in many places, especially in Brazil. The door to hands-on exploration was being shut.  

Because of that, we asked ourselves a simple question: Why don’t we make our own?

What started as a personal garage project evolved into a mission. The High Boy isn’t just another gadget; it’s our answer. It’s a pro-level, 100% open-source tool, created for anyone who believes knowledge should be accessible.  

Small in size, giant in possibilities. This is the High Boy.

Open by nature, both its hardware and firmware are designed for transparency and collaboration. Anyone can learn, modify, and develop everything from automation experiments and network diagnostics to embedded systems education.

With Wi-Fi, BLE, NFC, Sub-GHz RF, infrared, and GPIO expansion, High Boy is the ideal educational companion for students, ethical researchers, developers, and makers who want to explore and understand the invisible world of signals around us safely and responsibly.

No More Modules. No More Hassle.

The pocket-tool scene is incredible, but it’s stuck in time. Why do the most-used tools still treat Wi-Fi as a second-class feature? The community was tired of workarounds: expensive modules, complicated installations, and a broken design just to get the most basic pentesting feature. We listened. And we solved it.

The secret? High Boy combines the power of ESP32-S3 and the ESP32-C5 working together.

While others need an external module just to “see” Wi-Fi, the High Boy offers native Dual-Band connectivity. It’s a smarter, cleaner, and significantly more powerful architecture.

The High Boy isn’t a clone. It’s the upgrade the community has been waiting for.

Meet Octobit: Your Guide to the Invisible

Hardware hacking can be intimidating. That’s why we created an adventure partner for you. Meet Octobit (or “Bit” to his friends).

Why an octopus? 🐙 Because, just like the High Boy, he’s a master of multi-functionality. Each of his 8 tentacles does something different.  

And yes, we’re nerds. The name is a pun: 8 tentacles = 8 bits = 1 byte.  

Octobit lives inside your High Boy, offering tips, insights, and making learning about the world around you fun and accessible. He’s the heart of our educational mission.

A Complete Lab in Your Pocket.

The High Boy packs the power of multiple tools into one compact, portable device, ready for you to learn, experiment, and create.

Analyze Dual-Band Wi-Fi (2.4 & 5 GHz) without the need for additional modules.

High Boy takes Wi-Fi learning to a new level. Thanks to its Dual MCU architecture, it natively scans both 2.4 GHz and 5 GHz networks to help you understand how modern wireless environments work. It displays signal strength, channel usage, encryption types, and router brands through a clear and intuitive interface designed for education and exploration.

Perfect for students, developers, and makers who want to learn how wireless systems communicate safely and responsibly.

High Boy includes tools to monitor and visualize wireless traffic in controlled, lawful environments, enabling users to study protocols, understand network behavior, and learn practical security concepts with a fast, smart, portable device.

With Bluetooth, High Boy can scan surrounding devices, monitor and test, and connect to the app we’re developing for iOS and Android, ensuring control and intelligence right in the palm of your hand.

With NFC, High Boy can quickly read and identify tags including MIFARE Classic, FeliCa, ISO 14443 A/B and other compatible formats. It reports protocol details in a safe, controlled environment so users can study how cards work and build educational projects. For networking, High Boy provides traffic-visualization and anomaly-detection tools for learning and diagnostics (e.g., unusual traffic patterns), intended only for lab or consented environments.

High Boy also includes NFC emulation features, allowing it to simulate different types of compatible tags such as MIFARE, FeliCa, and ISO 14443. These features are designed for system integration, protocol research, and educational experiments in controlled environments always focused on safe, responsible, and professional use.

Powered by the CC1101 transceiver, High Boy supports common Sub-GHz bands (315/433/868/915 MHz) and nodulations like OOK/ASK and FSK/GFSK. It lets you analyze spectrum activity, detect signals, and capture frames from low-data-rate systems such as loT devices, smart sensors, and remote controls.
 

Users can adjust power, data rates, and filters to run diagnostics and learn real-world RF concepts safely. Designed for education, protocol analysis, and controlled interoperability testing, not for unauthorized transmission or interference.

The High Boy works as a universal infrared controller capable of learning and transmitting signals to TVs, projectors, or appliances.

It’s a great tool for learning about infrared communication protocols, home automation projects, and DIY prototyping.

The built-in receiver captures common IR signals and stores them for replay so you can control your own authorized devices directly from High Boy or the companion app.

The High Boy supports HID functionality, allowing you to use it as a keyboard and mouse to execute commands and scripts in personal, educational, or prototyping projects. It also supports remote control via Bluetooth (BLE) for secure wireless interaction and monitoring in connected environments.

Its extra GPIO pins allow modular expansion and connection to external sensors or boards.

High Boy supports UART, SPI, and I²C protocols, enabling creative projects in automation, robotics, and electronics education.

Insert a microSD card (up to 32 GB) to store logs, captures, backups, and firmware updates. Everything can be updated directly from the card simple, fast, and secure.

High Boy is fully open-source, powered by the ESP-IDF framework (Espressif).

You can customize firmware, add new modules, and share your work with the community.

Our goal is to create a collaborative learning platform where innovation, experimentation, and transparency come together.

Learn, build, and explore safely.
