LimeNET Micro makes deploying wireless networks more accessible than ever before, by extending the LimeNET line of integrated hardware solutions via an ultra-low cost platform that is capable of supporting narrowband systems, such as GSM and IoT wireless standards in a stand-alone configuration.
As with existing integrated LimeNET platforms, the new LimeNET Micro is built on the very same revolutionary field-programmable RF (FPRF) technology and features the LMS7002M transceiver at its heart. However, this highly cost-optimised single board solution also integrates GPS for high-accuracy timing, Power over Ethernet (PoE), and embedded compute for fully standalone operation.
In utilising the Raspberry Pi Compute Module 3, LimeNET Micro builds on previous platforms to further democratise wireless networks in much the same way that the Raspberry Pi has democratised embedded computing.
Given its incredibly low price point and highly integrated nature, there are endless application possibilities for LimeNET Micro, ranging from cellular networks and IoT, through spectrum monitoring, test and measurement, amateur radio, and radio astronomy.

LimeNET Micro with Raspberry Pi Compute Module (bottom)
A Raspberry Pi Compute Module 3 is included with every purchase of a LimeNET Micro (excluding early bird units). Raspberry Pi Compute Module 3 Lite‘s will also work with LimeNET Micro, but would require use of the separate microSD slot.
The custom aluminum case in this kit not only physically protects your LimeNET Micro, but it helps reduce noise interference. It also looks and feels smashing. The Aluminum Kit is the only pledge level that includes a Compute Module pre-loaded with a PantaHub software stack. The aluminum case is only available for sale as a kit.
The acrylic case is custom-designed to keep your LimeNET Micro safe. And the kit is made to give you all the components you need to get started right out of the box.
Full kit includes:
We’re offering omni-directional antennas with SMA connectors, optimized for frequency ranges of 800-960 MHz, 1710-2170 MHz, and 2400-2700 MHz. These are the same same antennas used with the LimeSDR-USB and the LimeSDR Mini.
The antenna offered during the campaign has a 3 M cable with an SMA connector and a 28 dB gain.
A small SO-DIMM form factor board plus ribbon cable to enable use of a classic/consumer Raspberry Pi with the LimeNET Micro.
As with the LimeSDR family, the LimeNET Micro is a free and open source project. We will be releasing code, firmware, schematics, layout, and associated project files via MyriadRF shortly.
The LimeNET Micro uses the same host-side software as previous LimeNET integrated systems, called Lime Suite. Lime Suite is entirely open source and supports a variety of software-defined radios and APIs. You can learn more about Lime Suite at its GitHub repository and MyriadRF project page.
PantaHub lets you connect your devices and transform them into bare-metal infrastructure. Designed for deeply embedded and high-grade enterprise systems alike, the Pantavisor device agent and PantaHub are the perfect choice for the management of Linux devices and their firmware lifecycles.
The PantaHub base image will be pre-loaded onto all Compute Modules included in the Aluminum Kit pledge levels.

As in the previous Lime Microsystems campaigns, the supply chain is the biggest risk – parts shortages could delay production. However, since the critical parts we’re using in LimeNET Micro are the same as those in the LimeSDR and LimeSDR Mini, the Micro will benefit from the considerable work we’ve already put into creating the LimeSDR supply chain.
All orders will be shipped from Crowd Supply’s warehouse in the United States. For a product of this scale, maintaining a separate fulfillment operation in Europe is not economically feasible and would actually increase the overall cost to the end customer. You can find out more about Crowd Supply’s shipping fulfillment in their Guide.
If you have a question about ordering, paying, or shipping, please refer to The Crowd Supply Guide.
If you have a technical question about the operation of the LimeNET Micro or any of its applications, please ask your question on the Myriad-RF forum.
