Device Overview
Biscuit is a family of portable WiFi and Bluetooth security research tools. Pro, Ultra, Crumb, and DIY devices connect to the Biscuit Manager app on iOS or Android. Biscuit Nodes are satellites controlled through a Pro or Ultra running in Manager mode.
The lineup includes purpose-built hardware (Pro, Ultra, and Crumb), a bring-your-own-board option (DIY), and a distributed scanning satellite (Node).

Which device is right for you?
-
Biscuit Pro – The flagship. Dual-chip architecture, dual-band WiFi 6, dedicated BLE gateway, battery monitoring, and mesh hub capability. Everything you need in one compact package.
-
Biscuit Ultra – Everything the Pro offers, plus an SD card slot for local PCAP storage, extended capture sessions, and external antennas for increased range. The form factor is the size of a small wifi router. Ideal when you need to capture more data than BLE bandwidth allows or need maximum range.
-
Biscuit Crumb – A compact, official single-chip Biscuit with 6 RGB LEDs, a unique serial number, and on-board portal storage. Same scanning capabilities as the Pro in a smaller package, without the SD card or dual-chip architecture.
-
Biscuit DIY – Build your own Biscuit using any supported ESP32-C5 board. Full scanning and attack capabilities with a single-chip design. Great for experimentation and budget builds.
-
Biscuit Node – A dedicated C5 satellite for a Pro or Ultra in Manager mode. Build a multi-radio rig for parallel WiFi/BLE wardriving and distributed authorized deauth.
