SparkFun MicroMod Asset Tracker Carrier Board

The SparkFun MicroMod Asset Tracker Carrier Board provides you with a toolkit to monitor and track the location of your assets.

Built around the u-blox SARA-R510M8S module, the asset tracker offers Secure Cloud LTE-M and NB-IoT data communication for multi-regional use and has an integrated u-blox M8 GNSS receiver for accurate positioning information. The SARA-R5 supports many different forms of data communication from full TCP/IP sockets and packet-switched data, through HTTP Get/Put/Post, FTP (the SARA has a built-in file system), Ping, to good old SMS text messaging!

The Asset Tracker Carrier Board has an integrated ICM-20948 Inertial Measurement Unit (IMU) for Nine Degree-Of-Freedom orientation and movement detection. Want to send a message if your asset is moved? The Asset Tracker can do that! The board also has a built-in digital microphone and so can send an alert as soon as noise is detected too.

The SparkFun Asset Tracker Carrier Board has a built-in micro-SD card socket for data logging as well as a SIM card port and included SIM card. Power options include both USB-C and LiPo battery (with built-in charging and battery fuel gauge), but you can provide power via a breakout pin too.

We’ve provided a full set of examples to get you up and running quickly and our SARA-R5 Arduino Library does all of the heavy lifting for you.

The Asset Tracker will work with any of our MicroMod Processor Boards, but because it offers so many features and can be configured in different ways, some Processor Boards may be a better choice for your application than others. Please see our Hookup Guide for further details.
