Survey the networks around you, read channels and signal quality, and raise the card’s own access point so the whole panel runs from your phone with no router in between.

Bluetooth with Low Energy. Discover and log the devices nearby with live signal strength, and emulate a keyboard or mouse for the machines you own.

Two LoRa radios on board, so the card works on the European 868 MHz band and on the American 915 MHz band without swapping a thing. Range that reaches far beyond Wi‑Fi, plus Sub‑GHz measurement for studying your own remotes and sensors, and Meshtastic compatible for off-grid messaging.

The external antenna is what turns a few hundred meters into kilometers on the LoRa and Sub‑GHz link when you have line of sight.

Read, write and compare 13.56 MHz tags. The clearest way to learn how contactless actually works, and the base for your own NFC projects.

Study the RFID tags that belong to you and see exactly what a reader picks up when one passes in front of it.

Learn and replay infrared codes, so one card stands in for the remotes of your television, air conditioning and projector.

Put NFC, RFID and your own code together to build access experiments of your own: a lock that opens with a tag you programmed yourself.

A microphone for acoustic work: measure ambient noise, trigger on a sound, or record a short sample straight to the microSD.

Channel State Information reads how the Wi‑Fi signal itself is disturbed as it crosses a room, turning an ordinary radio link into a sensor for presence and movement. Tell whether a room is occupied and how that changes through the day, using the radio rather than a lens.

Put CSI, signal strength and the radar together and watch presence and movement nearby plotted live on a sweep display in the panel, with no camera anywhere in the setup.

An RGB status LED and a piezo buzzer report back without a screen: scanning, connected, transmitting or waiting for you. Alerts, confirmations and locator tones, with a full library of tunes when you want it to be fun.

Native USB‑C for power, charging and one-cable firmware flashing straight from the browser. No programmer and no drivers to install.

Host mode, so the card can drive the machine it is plugged into. Prototype keyboard and mouse macros to automate repetitive tasks on computers you own.

Portable storage for logs, captures and configurations. Eject the card and read everything on any computer.

Arduino and ESP‑IDF compatible with the pin map documented. Flash new code over the same USB‑C cable from the browser, with no toolchain to set up before your first build, then fork the firmware and add whatever module your project needs.
