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.
