Biscuit Crumb

Biscuit Crumb

Compact hardware. More ways to explore.

Biscuit Crumb brings Biscuit into a smaller package. Built around a single ESP32-C5, it’s a compact wireless toolkit for wardriving, wireless exploration, and authorized security testing. Connect directly to Biscuit Manager on your phone or add it to your Pro or Ultra setup as a satellite Node. A six-NeoPixel ring delivers visual feedback with a look all its own.

Wardriving

• Scan 2.4GHz and 5GHz WiFi networks or nearby Bluetooth devices using your phone’s GPS
• View live maps, clustered markers, and heatmaps in Biscuit Manager
• Save sessions and review your results after the drive
• Add another scanner to a Pro or Ultra setup through satellite Node mode

Single C5. Smaller footprint.

One ESP32-C5 handles the wireless tools and connects to your phone over BLE. Crumb keeps the hardware compact with a single-module design, onboard flash storage, and app-driven controls.

Satellite Node Support

Expand your existing Biscuit setup by using Crumb as a satellite Node, with a WiFi or BLE scanning role for your session.

Important: Crumb is a Node only. It cannot act as a Node Manager or manage other Nodes. Use a Biscuit Pro or Ultra as the Node Manager.

WiFi & Bluetooth Tools

• Dual-band WiFi 6 scanning across 2.4GHz and 5GHz
• Bluetooth scanning and testing tools
• Evil Portal and Karma for authorized security assessments
• Onboard flash storage for portal templates and captures

Operational Features

Six-NeoPixel LED ring
See activity directly on the device. Adjust brightness, choose LED effects, or turn the lights off through the app.

Biscuit Manager
Connect from iOS or Android to select tools, manage the device, and install firmware updates over the air.

Badge Mode
Start Badge Mode from the app, then disconnect your phone. Crumb uses its LED ring to signal supported nearby devices and deauthentication activity. This mode saves no logs and ends when the device is power-cycled.
