SoDeRa: An upcoming low cost app-enabled open-source 100 kHz to 3.8 GHz SDR Transceiver

A new software defined radio called SoDeRa (SOftware DEfined RAdio) is currently under joint development by companies Canonical (the company behind the Ubuntu OS) and Lime Micro. SoDeRa is based on the new Lime Microsystems LMS7002M Transceiver chip which has a 100 kHz – 3.8 GHz range. The transceiver chip interfaces with an Altera Cyclone IV FPGA with 256 MB of RAM and a USB3 controller, and the whole radio will have 4x TX outputs and 6x RX inputs.

The people behind this SDR are currently marketing SoDeRa as “the Arduino of the Telecom and Radio Engineer”. It appears to be designed mainly to implement IoT and other radio communications protocols, but it also sounds like it could find excellent use in the hobby and amateur market as well as have benefits for the average person. Interestingly, the developers also plan to implement an app store which would allow you to essentially download a radio and instantly configure the SoDeRa SDR for any desired protocol or application. They write:

This is the first time that a revolutionary device for which we are organising a joint crowd-funding campaign with Lime Microsystems is made public. The #SoDeRa is the cheapest software defined radio you can buy. The #SoDeRa will have an app store and will be able to provide any type of (bi-directional) radio communication going from LTE, Lora, WiFi, GPS, Bluetooth, radar, radio-controlled toys/robots/drone, digital radio, digital TV to even MRI scanners, satellite and air traffic communications by just installing an app. The #SoDeRa is the Arduino of the Telecom and Radio Engineer.

The VP of IoT at Canonical also writes:

The SoDeRa is powerful enough to be a full MiMo LTE base station with long range coverage, provided you add the right antenna. You can via apps put other wireless communication protocols like LoRaWAN, Bluetooth, Zigbee, Z-Wave, GPS, Galileo, Airspace protocols, radar, MRI scanning RF, TV/Radio, any toy/robot/drone control, White Space, etc. But most importantly because of its price and ease of adding more protocols, the SoDeRa will enable anybody to define competing wireless communication protocols and put them into Github. Developers don’t like closed standards like LTE or complex standards like Bluetooth & Zigbee. The future will allow developers to compete against corporations and standardization bodies if they think current standards can be improved upon. The Internet has shown that this dynamic brought us easier standards through adoption like JSON and Yaml vs XML and EDI. Wireless, RF and telecom engineers never had an Arduino like the electronics engineers. The SoDeRa will plug this hole.

Development on SoDeRa is working towards a trend in radio systems where all radio devices are software defined, allowing for futuristic features like advanced spectrum control and the ability to change protocols on the fly. They write:

Including #SoDeRa in any type of smart device will greatly reduce the cost of deploying a mobile base station network because by open sourcing the hardware design it will become commodity. By including software defined radio in lots of devices, often with a completely different purpose, will allow these devices to become a smart cell via installing an extra app. In the future, support for software defined radio will likely be embedded directly in Intel and ARM chips. The foundational steps are already happening. This will likely reshape the telecom industry. Not only from a cost perspective but also from a perspective of who runs the network. Telecom operators that don’t deliver value will see their monopoly positions being put in danger. As soon as spectrum can be licensed on a per hour basis, just like any other resource in the cloud, any type of ad-hoc network can be setup. The question is not if but when. Open sourcing and crowdfunding will make that “when” be sooner than later. Smart operators that align with the innovators will win because they will get the app revenue, enormous cost reductions, sell surplus spectrum by the hour and lots of innovation. Other operators that don’t move or try to stop it will be disrupted. What do you want to be?

At first glance SoDeRa sounds like it will be an expensive device, but on their official website they are currently running a survey asking people what they would be willing to pay, and the lowest price given is $50 – $99. This makes it seem likely that in the future with enough volume SoDeRa could be sold at very low cost and become very popular.

I am willing to pay for 1 unit

  • $50 – $99 (lead time 9 months)
  • $100 – $199 (lead time 6 months)
  • $200 – $299 (lead time 3 months)
  • $300 – $399 (lead time 2 months)
  • $400 – $500 (lead time 1 month)

It sounds like the team behind SoDeRa are gearing up for a crowd funding campaign so we will be keeping an eye on this SDR.

Radio Hams can play as much as like, and for RX applications who cares if not got FCC ETSI regs or not


Looks like they are going to be launching an indiegogo campaign soon, per most recent tweet.


This seems like a massive amount of marketing spam for something that is nothing more than piece of hardware. Who will develop all of that source code, does Canonical have an army of signal processing engineers capable of taking on Qualcomm and Broadcom? Their only hardware foray, the Ubuntu phone was an abysmal failure. This isn’t a piece of software like Linux or GNURadio, who will maintain FCC/IC/ETSI certification? I’m trying to understand what they’re offering here than some hardware and a bag of empty promises by what appears to be clueless marketing people.

Go away

Sounds like you’re a little butthurt there. Features looking better than your offering, hmm?


Kind of wondering if they are going to get FCC Part 15 authorization (non-licensed low-power transmission)

Although an operator does not have to obtain a license to use a Part 15 transmitter, the
transmitter itself is required to have an FCC authorization before it can be legally
marketed in the United States. This authorization requirement helps ensure that Part 15
transmitters comply with the Commission’s technical standards and, thus, are capable
of being operated with little potential for causing interference to authorized radio



The link to the LMS7002M part on the SoDeRa page is busted. Here’s where you can download all the technical information on the radio SoC (data sheets, etc.):


That USB connection is a recipe for disaster, please make a more robust connector and also provide some protection from nearby signals, unlike the ridiculously easy to blow HACKRF which is now a useless paperweight and the maker doesn’t return emails

Mighty Mik

i’m gonna call BS on this “The #SoDeRa is the cheapest software defined radio you can buy. ” Throwing that FPGA in there is gonna blow that claim. 4 TX and 6 Rx? Lowest cost is still the RTL dongle, and that can be hooked up to a Kindle Fire which can be had for $35 on sale. even at $50 retail and the $25 dongle that’s still well under $100 (OTG cable $1 – $3) for a portable SDR receiver that goes 24 MHz to 1.7 Ghz. It’ll be lucky to hit a sub $200 price point IMHO.

When they say “cheapest software defined radio” I think they mean a transceiver. The RTL-SDR and similar units are receive-only.


Those were my thoughts as well.

I’m looking forward to this. It looks really interesting and as long as they don’t price it out of the hobby market then I think it will be a success. Assuming the hardware stands up to usage and app market prices remain affordable.

I have to say I’m not too excited about the antennas I see on the case, and a lack of SMA connectors is a drawback. I haven’t seen many semi-rigid coax runs with that type of mini connector on it (someone help me with the name please – brain dead at the moment). Can always use adapters I reckon.

If the makers are reading this, send me a unit. Let me break it in a little.

Dave H

I get the feeling that image of the case and antennas is a 3D rendering. Most 3D illustrators I know (with a couple of notable exceptions) think the “Rule of Cool” supersedes mundane things like physical laws.
