HellBoy CYD-32 – ESP32 Cybersecurity & IoT Development Platform

Build. Develop. Prototype. Expand.

The HellBoy CYD-32 is a compact ESP32-WROOM-32 (8MB Flash) development platform designed for embedded development, IoT prototyping, automation projects, robotics, hardware experimentation, and cybersecurity research.

Unlike feature-packed all-in-one devices, the HellBoy CYD-32 is designed as an open expansion platform, allowing developers to connect only the hardware they need through its 2×10 GPIO Expansion Header.

Whether you’re building wireless projects, testing sensors, developing firmware, or creating custom hardware, HellBoy gives you a clean and expandable foundation without forcing unnecessary onboard peripherals.
