Device Overview

Biscuit is a family of portable WiFi and Bluetooth security research tools. Every device in the lineup connects to the Biscuit Manager app on iOS or Android, giving you a full wireless toolkit controlled from your phone.

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 and a unique serial number. 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 small scanning satellite that pairs wirelessly with a Biscuit Pro or Ultra. Keep multiple Nodes together with your hub to build a “Node rig”, distributing channels across all connected Nodes for specialized, parallel spectrum coverage.
