Introducing the SigBin Pro — Dual MCU BW20-07s Built for Modern Wireless Research

The SigBin Pro is the most capable device we've built at SigBin Labs. It's a dual MCU research platform centered around the BW20-07s module — a compact, dual-band chipset with real wireless research capability built in.

What is the SigBin Pro?

The SigBin Pro is a purpose-built wireless research device designed for field use. It's compact, battery-friendly, and requires no laptop or phone to operate. Everything runs on-device — scanning, logging, GPS tagging, and storage.

It is designed for:

• Wireless network research in authorized lab and field environments
• Wardriving with GPS-tagged logs compatible with WiGLE and wdgwars
• Dual-band coverage across both 2.4GHz and 5GHz networks
• Education and hardware experimentation for those learning embedded wireless systems

The BW20-07s module

At the core of the SigBin Pro is the Realtek BW20-07s — a dual-band Wi-Fi and Bluetooth module that operates across both the 2.4GHz and 5GHz spectrum. This is a significant hardware step up from single-band platforms commonly used in entry-level research tools.

The BW20-07s gives the SigBin Pro the radio capability needed to work with modern network environments, including networks running on the 5GHz band which older tools simply cannot see.

Why dual MCU?

The SigBin Pro uses a dual MCU architecture — two separate processors working together:

• Primary MCU — dedicated to radio operations via the BW20-07s. Handles Wi-Fi scanning, band selection, and packet-level work without interruption
• Secondary MCU — handles everything else: display, GPS integration, SD card logging, user input, and power management

This separation is intentional. Keeping radio work isolated from I/O means cleaner operation, more reliable logging, and headroom for research tasks that demand consistent radio performance.

WPA3-aware hardware design

Modern networks increasingly run WPA3 — the latest Wi-Fi security standard. WPA3 brings stronger encryption and updated management frame behavior compared to WPA2.

The SigBin Pro is built with this in mind. Its dual-band radio and capable MCU architecture are selected to handle modern network environments where WPA2 and WPA3 coexist. Researchers studying current wireless infrastructure need hardware that can see and interact with both generations — the SigBin Pro does that from a single, portable device.

Built for the field

Every SigBin Pro unit is:

• Hand-assembled in small batches — no mass production
• Field-tested before shipping
• Compact and portable — designed for bag or vehicle use during wardriving sessions
• SD card logging — no software needed to collect data, just pull the card
• GPS-integrated — every logged network is tagged with coordinates for WiGLE and wdgwars submission

Who is the SigBin Pro for?

The SigBin Pro is for people who take wireless research seriously:

• Wireless security researchers who need reliable, portable dual-band hardware
• Wardriving competitors who want GPS logging and wdgwars-compatible output without carrying a laptop
• Hardware hobbyists exploring embedded systems, dual MCU design, and BW20-07s development
• Educators running wireless security labs who need purpose-built hardware rather than adapted consumer gear

Responsible use

SigBin Labs hardware is built for authorized research, education, and lawful experimentation. The SigBin Pro is intended for use on networks you own or have explicit permission to test. All orders are manually reviewed before confirmation — we take responsible use seriously.
