Biscuit Ultra
The Biscuit Ultra has everything the Biscuit Pro offers, plus an SD card slot for local storage. If you need long-running packet captures, extended wardriving sessions, or want to store Evil Portal credentials locally, the Ultra is the device for you.
Everything in the Pro, Plus SD
The Ultra shares the same dual-chip architecture as the Pro – an ESP32-C5 scanner paired with an ESP32-WROOM system manager. It supports dual-band WiFi 6, BLE 5.0, battery monitoring, mesh hub capability, OTA updates, and all the same scanning and attack features.
The addition is an SD card slot connected directly to the C5 scanner chip.
What the SD Card Enables
Local PCAP Storage
Capture raw wireless packets and write them directly to the SD card as PCAP files. This is ideal for extended capture sessions where streaming packets over BLE to the app would be too slow or where you need to capture more data than BLE bandwidth allows.
Long-Term Packet Capture
With SD storage, you can run packet captures for hours without worrying about BLE throughput limits or app connectivity. Start a capture, walk away, and retrieve the PCAP files later.
Evil Portal Credential Storage
In addition to the on-board flash storage available on the Pro, the Ultra can store Evil Portal HTML templates and captured credentials on the SD card. This gives you more storage space for custom portal pages and ensures credentials are saved locally even if the app disconnects.

When to Choose the Ultra Over the Pro
- You need external antennas for maximum signal range and capture capabilities
- You need significantly longer battery life (the 3200mAh battery offers 3x the life of the Pro)
- You plan to run long packet capture sessions
- You want to store large PCAP files locally rather than streaming over BLE
- You need extra storage for multiple Evil Portal templates
- You want local credential backup independent of app connectivity
If you don’t need SD card storage, external antennas, or a larger battery, the Biscuit Pro is a more compact alternative.
