What is the SODAQ SARA SFF R412M?
The SODAQ SARA SFF R412M is an NB-IoT / LTE-M Supported, Arduino compatible, developer board that gives you access to all NB-IoT / LTE-M bands implying coverage across Europe, North America, Africa and Asia. Furthermore, this board has EGPRS fallback for all other regions. The name "SARA SFF R412M" originates from the powerful cellular module utilized within this board. Evidently, this module alone does not make the SODAQ SARA SFF the powerhouse it is - for that, we developed a low power consumption board that can be powered by solar / battery (2 JST connectors). Furthermore, we built in a range of high quality modules such as our integrated Microcontroller (Microchip Atmel SAMD21), GPS (uBlox EVA 8M for GPS, Galileo, GLONASS, and Beidou support, depending on the variation you pick) and Sensors (LSM303AGR digital magnetometer and accelerometer). The board further comes with a small (NB-IoT / LTE-M) antenna that connects to the uFl port as well as a small ceramic GPS Antenna and a free 800mAh lithium ion battery to get your prototypes off the ground straight away!
However, there's one thing that really sets this engineering masterpiece apart. Namely, the size - a miniscule 50 mm x 25.4mm. That's around the size of a small matchbox!
What can the SODAQ SARA SFF R412M do?
Besides being able to implement this device into almost every project due to it's tiny size, this device also packs quite the punch with it's extensive list of features
Imagine you need to create a new IoT project where you need to track multiple containers / cows / literally anything over a range of countries. SODAQ boards provide the ultimate low power solutions that would allow you to bring your devices to fully sustained autonomy. If you were to put this SODAQ SARA SFF board in an enclosure, attach a small battery and a solar panel, you have a fully autonomous solution that requires no manual adjustments. Updates? Easy, these can go over the air. Support? we have a forum for that where our engineers answer any questions.
By utilising the SODAQ SARA SFF, you already have a full solution as it has a GPS built in, which would allow for tracking, as well as an accelerometer to detect movement. Whenever the device is moved, you could, for example, program it to send the GPS location. Everything is fully customisable, making this the perfect board for prototyping and scaling. The power consumption in sleep will be ~26uA.
What makes it so special?
We have now established a few things: firstly, this board is able to utilize all NB-IoT bands as well as LTE-M, implying that you can send your data over a tested network with the power of the latest module, with minimal energy expenditure, allowing for longevity of projects. Secondly, this board has GPS, accelerometers, microcontrollers and antennas built in, meaning that you get an off-the shelf product that can act as a tracking device. Thirdly, this thing is tiny for the immense amount of built in features. Remember - it utilizes NB-IoT, LTE-M has built in sensors and is fully programmable. All for the size of a matchbox.
Two more things set this board apart:
1. The SODAQ SARA SFF is fully Arduino compatible. This means that every single open-source code written can be used on the SODAQ SARA SFF. On top of this, you can attach it to a SODAQ ONE baseboard and instantly connect a range of grove connectors, allowing you to connect whatever sensors you want to the board. Want your project to involve the measurement of water quality? Attach a water quality sensor to the base board grove connector. Want it to act as a portable security device? Attach a IR sensor through the grove connector. The possibilities are endless with this device, especially given it's potential autonomy that you would not get with the traditional boards and their heavy power consumption.
2. SODAQ knows quality. This implies that every product we release involves countless R&D projects and thorough testing before bringing anything to the market. This is also the reason why key IoT players such as Vodafone choose our hardware to demonstrate the power of their network. They wouldn't choose our boards if they could not maximise their network, establishing an objective level of robustness in our designs.

Below is an example of a water quality project we created for a client with our SODAQ AFF board. We utilised an EC sensor (electrical conductivity) attached to our SODAQ SARA boards to consistently send a signal of water quality, powered autonomously by the sun and tracking a range of things such as temperature, speed, location and evidently water quality. This is the overview of one board, but you could create comparison charts as evident on the picture to contrast between measurements at certain locations.
Another example of a successful integration of this product is the utilization of our universal tracker code. Here, we simply uploaded the aforementioned universal tracker code for an easy read of a few key variables:
Microchip Atmel SAMD21, 32 bit Arm Cortex
uBlox Sara R412M, all NB-IoT bands, LTE-M, EGPRS Fallback
For EGPRS an a connected battery is required to handle the higher power usage
LSM303AGR digital magnetometer and accelerometer
With every purchase from the Netherlands, it is required to activate the board. For this, a SIM Card is required. If you would like to work with LTE-M, within the Netherlands it is possible to get a SIM Card by registering the board to KPN. For all other countries we recommend contacting your local provider for a Sim Card compatible with the board.
The boards get supplied with a U.FL PCB antenna.
