Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SS114990813:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description RF Explorer 3G+ IoT modules are ready to use, advanced Spectrum Analyzer devices you can configure and control any way you want, from an Arduino, Raspberry Pi, or any other programming platform. 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. RF Explorer 3G+ IoT boards are delivered in two modes configuration modes: - Raspberry Pi - Arduino and compatible boards (3.0 – 3.3V only) We recommend Raspberry Pi mode for advanced usage and more powerful libraries, and Arduino for simpler, non-Linux software libraries related development. For best flexibility, these two boards can be easily re-converted between modes by soldering a required connector: - Raspberry Pi Hat can be converted to Arduino Shield by soldering standard 0.1” male headers to the PCB - Arduino Shield can be converted to Raspberry Pi Hat by soldering a 13x2 0.1” female header 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 BeagleBone, Chip, Chipkit, Teensy all them can easily control a RF Explorer 3G+ IoT by manually connecting to a standard UART port. Visit here for more details and examples. We also arranged a tutorial about ‘How to fit the RF Explorer 3G+ IoT modules on a Seeeduino board’. please click here to visit. **Features** - Design and customize your own Spectrum Analyzer, RF Detector, RF Sniffer, etc - Open source design, open source libraries and examples - Supported by all Arduino and Seeeduino 3.3V boards. - Suggested platforms: - Arduino DUE (best performance) - Seeeduino (lower cost and size) - IMPORTANT: Do not use on 5V Arduino boards or will damage the IoT Shield - Flexible board: can be connected to a Raspberry Pi by soldering a compatible female header - Recommend to select SMA antennas for specific application - For future firmware upgrades, or if you are using a small form-factor Arduino and want UART connection to PC - you should get a USB CP2102. **Specification** - Frequency Band Coverage: 15-2700MHz - Antenna Connector: Standard SMA 50 ohms - Advanced Selectable Internal Input Stage: Normal, LNA, 30dB Attenuator - Amplitude Resolution: 0.5dBm - Dynamic Range: -130dBm to +10dBm - Absolute Max Input Power +30dBm - Average Noise Floor Level (typical with LNA enabled): -120dBm - Frequency Stability and Accuracy (typical): +-10ppm - Amplitude Stability and Accuracy (typical): +-3dBm - Frequency Resolution: 1Khz - Resolution Bandwidth (RBW): automatic 3Khz to 600Khz - Power Consumption: 100-500mW - All modules are factory calibrated ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/h/t/httpsstatics3.seeedstudio.comseeedimg2016-12jmjknrdtox8thrvz5zurovwy.jpg)
