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.

Well the biscuit crumb is definitely a great little piece of tech the led are super bright and controllable so there not as bright. The badge mode is super useful when out in roaming around it’s useful know what around your area. Great product would recommend to like minded friends and family
Awesome product that fits almost anyplace ;)
Making more biscuits to buy biscuits!!
;)
I have a Biscuit collection forming. I have an Ultra and several Pros. Now, I have a Crumb. I tell you thins so you know that I have experience with other Biscuit products from which I can draw my conclusions. I am trustworthy source of information. Trust me. You can trust a stranger, right? :)
Anyway, I have been putting this little dude through the wringer. It is small enough to fit into any pocket and forget it. If I am not driving with it, I keep it in my pocket everywhere I go. The battery lasts for hours and it just keeps on scanning! Even with the lights turned on and going. I already thought the Pro was super portable, and it is, but the Crumb gives a whole new meaning to the meaning of portable! Even when running for hours at a time in my pocket it does not get hot and still picks up signals just as effectively as it does on a tabletop.
I love mine. I will get another when they get restocked. I recommend you do the same. Oh yeah, the lights are awesome to play with too! they are adjustable for the various modes and you can set them to be what you want (including off if you don't want them on). Hedge hit another home run with this one!
As an aside, The colorful lights can also make it seem more attractive to a younger audience. The Crumb could possibly be a great tool for introducing kids to the world of wireless networks and all of the exciting technology that surrounds it. Flashing colorful lights make the Crumb seem like a fun toy rather than some boring tool, and it might spur the imagination and generate interest. In a world of brainrot and distraction, getting kids interested in science and technology early might encourage them to pursue STEM topics when they get older and promote healthy learning habits, fostering a positive attitude toward education, which society desperately needs!

The crumb should have been called the slice because it’s darn sure more than just a speck! It is literally the all in one EDC carry for those in the cybersecurity field. The badge ability with the different variations of LED lights is a awesome way to notify the user if there are things around that should be paid special attention to.
The Biscuit Crumb makes the perfect newest addition as another encrypted node to my already existing Biscuit Ultra (master) and Pro (encrypted node) cluster.
Its great! It works exactly as intended and I love the LED's
Awesome product, speedy delivery to mainland Europe
The Biscuit Crumb is a continual improvement on the line of Biscuit products. Even with its smaller size, it is still able to perform on par with the Pro. The Crumb’s lighting feature is also another welcome addition to the product that helps the user know what the device is currently doing. I look forward to any other new products and improvements added to these amazing devices.
Absolutely phenomenal product!!! I love it! The hardware is magnificent and the app on Android is the stuff of dreams!👍🏽👍🏽👍🏽👍🏽
This thing is FIRE! Def glad to add to my bag!
Still playing around with it but I love it. Great UI with iPhone so I’ve enjoyed bringing it with me on my travels.
Neat little gizmo. Battery lasts about 4 hours, which is better than I thought it'd do, so I'm pleased all around.
Another fantastic product with awesome customer support, I've got the ultra pro and crumb, all perfect. Thanks
Awesome device! I love the size and how perfect it is for keeping on you at all times. I have been able to keep this in my pocket all the time and when I’m away form my car I can start this little guy, with lots of power, up and still run some scans or do war walks!
Love it! Works great
