Vszerda 3Pcs CC2531 USB Dongle Module Bare Board Packet Protocol Analyzer

SKU CH-03WY-FWANP

Three bare-board CC2531 USB dongles for Zigbee packet analysis and ZB2MQTT home-automation integration

  • Three CC2531 dongles for parallel ZB 2mqtt gateways
  • Pre-flashed CC2531ZNP-Prod firmware enables immediate ZB 2mqtt use
  • USB interface plugs directly into PC or Raspberry Pi
  • Two buttons and two LEDs give local status control
  • Eight IO connectors plus debug header expose all pins

Vszerda CC2531 USB Dongle Kit

This set contains three bare-board CC2531 USB dongles designed for IEEE 802.15.4 and Zigbee packet analysis. Each module arrives with CC2531ZNP-Prod firmware already flashed so it works immediately with Zigbee2MQTT for home-automation control of devices such as BASICZBR3 and S31 Lite Zb. The compact stick measures 5.6 by 1.6 by 0.7 centimetres and plugs straight into a PC or Raspberry Pi. Two buttons and two LEDs give basic user interaction while eight exposed IO pins provide a debug interface.

Check USB Port And Firmware Needs

Verify that your host has a free USB-A socket and runs an operating system supported by Zigbee2MQTT before ordering. The dongles ship with production firmware installed, yet some advanced setups may require a fresh flash; ensure you have the tooling and confidence to reflash if your automation stack demands a different image. No external antenna connector is present, so placement near the coordinator matters for reliable mesh coverage.

Sustained Sniffing And Coordinator Duty

During long capture sessions the bare board stays cool because the CC2531 draws only modest current from the USB bus. Continuous packet sniffing or acting as a permanent Zigbee coordinator does not throttle the radio or cause thermal shutdown. The two status LEDs remain visible for diagnostics while the eight IO pins stay accessible for logic-analyser probes throughout extended debugging runs.

Questions about this item

What comes in the package and is anything else needed to use the dongles?

The package contains three CC2531 USB dongle modules. Each unit is a bare board with a USB interface, two buttons, two LEDs and eight IO connectors exposed for debugging. No cables or accessories are included; the board plugs directly into a USB port on a PC or Raspberry Pi.

The listing mentions BASICZBR3 and S31 Lite Zb — which version should I choose?

The three dongles are identical hardware, each pre-flashed with CC2531ZNP-Prod firmware for ZB 2mqtt. There are no alternative versions or capacities to select; all three units support the same IEEE 802.15.4 / ZB applications such as BASICZBR3 and S31 Lite Zb.

What does the 5.6 × 1.6 × 0.7 cm size mean when the dongle is plugged into a real machine?

The board measures 5.6 cm long, 1.6 cm wide and 0.7 cm thick, so it occupies a single USB-A port without blocking adjacent ports on most PCs or Raspberry Pi boards. The bare PCB has no enclosure, leaving the eight IO pins and debug interface accessible while inserted.
