These modules are cost-effective platforms to develop your own customized Spectrum Analyzer, Power Detector, RF activity alarm, RF sniffer, RF QA test bench, etc.

Programmability and network capabilities of the hosting platform enables remote control and diagnosis scenarios, fully automated RF alarm systems, advanced assistance for unattended detection requirements such as those of radio operators, cell towers and HAM stations. These modules are also small and low weight so you can add it onboard on any FPV plane or quadcopter and use to scan the flight area to detect interferers.

RF Explorer 3G+ IoT boards are delivered in two configuration modes:

  • Arduino and compatible boards (3.0 – 3.3V only)
  • Raspberry Pi

For added flexibility, these two boards can be easily re-converted between modes by soldering a required connector:

  • Arduino Shield can be converted to Raspberry Pi Hat by soldering a 26x2 0.1” female header to the PCB
  • Raspberry Pi Hat can be converted to Arduino Shield by soldering standard 0.1” male headers to the PCB

Designed in this way, it is easy to reconvert the board to a different hosting platform with no extra cost if you have different needs down the road.

Furthermore, other platforms such as BeagleBoard, Chip, Chipkit, Teensy all them can easily control a RF Explorer 3G+ IoT by manually connecting it to standard UART port.
